19 FeedWordPress is an Atom/RSS aggregator for WordPress. It syndicates content from feeds that you choose into your WordPress weblog, and then the content it syndicates appears as a series of special posts in your WordPress posts database. If you syndicate several feeds then you can use WordPress's posts database and templating engine as the back-end of an aggregation ("planet") website. It was developed, originally, as a utility/hobby project, because I needed a more flexible replacement for [Planet][] for aggregator sites that I administered.
20
21 [Planet]: http://www.planetplanet.org/
22
23 FeedWordPress is designed with flexibility, ease of use, and ease of configuration in mind. You'll need a working installation of WordPress (version [4.5][] or later), and it helps to have SFTP or FTP access to your web host. The ability to create cron jobs on your web host is helpful but not required.

27
28 == Installation ==
29
30 To use FeedWordPress, you will need:
31
32 * an installed and configured copy of [WordPress](https://wordpress.org/) (version 4.5 or later).
33
34 * the ability to install new plugins on your site using either WordPress's Plugins Repository, SFTP, FTP or shell access to your web host
35
36 = New Installations =
37
38 1. Download the FeedWordPress installation package and extract the files on your computer.
39
40 2. Create a new directory named `feedwordpress` in the `wp-content/plugins` directory of your WordPress installation. Use an FTP or SFTP client to upload the contents of your FeedWordPress archive to the new directory that you just created on your web host.
41
42 3. Log in to the WordPress Dashboard and activate the FeedWordPress plugin.
43
44 4. Once the plugin is activated, a new **Syndication** section should appear in your WordPress admin menu. Click here to add new syndicated feeds, set up configuration options, and determine how FeedWordPress will check for updates. For help, see the [FeedWordPress Quick Start][] page.

69
70 * IMPORTANT SECURITY FIX: This version includes an important fix for a security vulnerability reported to me through WPScan and WordPress support channels.
71
72 Vulnerability CVE-2021-25055 allowed for an XSS (Cross-Site Scripting) attack using a specially crafted URL for a page within the FeedWordPress admin interface. (To be exploited, an existing user with login credentials that allow them to access the FeedWordPress dashboard would have to follow the malicious URL and log in.) This vulnerability has been corrected in the current version; to protect your site's security PLEASE BE SURE TO UPGRADE AS SOON AS POSSIBLE to version 2022.0123 or later, via the WordPress Plugin Repository or via Github.
73
74 * BUG FIXES: Fixes a number of small possible bugs when creating new syndicated posts under unusual conditions -- a sanity check is built in to avoid infinite loops in case of certain unexpected error outcomes when creating new users; some more possible sources of PHP 8 "Countable" warnings are eliminated, etc.
75
76 = 2021.0713 =
77
78 * WORDPRESS 5.6, 5.7.x COMPATIBILITY FIXES. This release introduces fixes to annoying or worse warnings resulting from
79 the deprecation of WordPress's built-in WP_Feed_Cache class. This should resolve the problem if you are encountering
80 annoying, worrying, or breaking problems related to the PHP warnings: "Deprecated: class-wp-feed-cache.php is
81 <strong>deprecated</strong> since version 5.6.0", and/or "Message: ./cache is not writable. Make sure you've set the
82 correct relative or absolute path, and that the location is server-writable."
83
84 * Fixes PHP warning for "count(): Parameter must be an array or an object that implements Countable in
85 .../wp-content/plugins/feedwordpress/feedwordpress.php on line 1566"
86
87 * Miscellaneous fixes for other missing variable and global warnings.
88
89 * Code cleanup and reorganization to allow better modularization of error messages, warning dialogs, and extended text.
90
91 = 2020.0818 =
92
93 * WORDPRESS 5.5 COMPATIBILITY FIXES, RESOLVES WARNING NOTICES OR WP-ADMIN LOCKOUT. WordPress 5.5 incorporated a newer release of SimplePie, version 1.5.5, which is pretty rad, but FeedWordPress classes that relied on SimplePie 1.3.1's method signatures would then produce PHP warning notices. That should be pretty innocuous, but depending on web server configurations, some users could get locked out of their own wp-admin interface by the display of error notices in the browser at inopportune times. In any case, I have added code to switch between backward-compatible modules for SimplePie 1.3.1 or updated modules compatible with SimplePie 1.5.5, based on the version available in your WordPress installation; so these notices and their untoward effects should be eliminated.
94
95 * PHP 7.4 COMPATIBILITY FIX: Magic quotes were deprecated and then removed back in PHP 5.x, and in PHP 7.4 the vestigial `get_magic_quotes_gpc()` function has been deprecated. We don't need to worry about it anymore for versions of PHP still supported by WordPress. The reference to the function in the MyPHP utility class caused PHP warnings in more recent versions of PHP; so it has now been removed.
96
97 * DIVERS BUG FIXES AND PHP WARNING NOTICES RESOLVED, thanks to @oppiansteve's fixes and pull requests. (Thanks!)
98
99 * JQUERY COMPATIBILITY FIXES, RESOLVES MYSTERIOUS VANISHING FEED SELECTOR IN WP-ADMIN. An upgrade to WordPress's packaged jQuery caused the drop-down box for feed settings (in Syndication > Feeds & Updates, Syndication > Posts & Links, etc.) to vanish shortly after pageload. That was awkward, so I disabled the now-incompatible interface chrome that was causing it to vanish.
100
101 = 2020.0118 =
102
103 * WORDPRESS COMPATIBILITY TESTING. It's been some time since a public release of FeedWordPress; so I have tested the plugin functionality with recent versions of WordPress and incorporated a number of PHP 7-compatibility related tweaks.
104
105 * FEED PARSING FAULT TOLERANCE. If FeedWordPress fails to parse a feed using normal XML functions, it will attempt to convert any named entities that may be causing a problem, and then try to parse again. Props to @inanimatt for utility functions that help make the code go.
106
107 * PAUSING UPDATES. In Syndication > Feeds & Updates, you can now instruct FeedWordPress to temporarily pause or resume updating feeds -- whatever update method you are using, you can put new updates on hold for a while so that you can fiddle with setings, run tests, or do whatever you need to do before allowing updates to resume.
108
109 * CODE MODERNIZATION, PHP 7.x COMPATIBILITY AND CLEANUP AND REORGANIZATION. I have been dusting out nooks and crannies in the code and hiving more functionality off into discrete modules. A number of FeedWordPress users have also offered pull requests to eliminate bothersome PHP notices and warnings related to PHP 7.x compatibility -- in particular removing uses of deprecated `each()` functions, and avoiding use of `count()` on null values -- which I have rolled into the main branch release. Props to @manzoorwanijk, @tristanleboss, @martinburchell and @oppiansteve
110
111 = 2017.1020 =
112
113 * ADD BOILERPLATE / CREDITS FEATURE AVAILABLE IN POSTS & LINKS SETTINGS PANEL. I have added a new settings panel to the off-the-shelf features of FeedWordPress, under Syndication > Posts & Links (or under the Posts settings page for any individual feed), which allows you to define boilerplate text that should appear in connection with every syndicated post, or with every post syndicated from a particular feed. So, for example, if you want each syndicated post to include a byline reading "This is a syndicated post, reprinted from (LINK TO ORIGINAL SOURCE WEBSITE).", you could set up this byline from within the FeedWordPress settings interface, by going to the Boilerplate / Credits panel, and adding a line to appear BEFORE the CONTENT of each syndicated post, using the text and shortcode "This is a syndicated post, reprinted from [source]." For those of you who have corresponded with me about this feature before, you may be familiar with it from the long-standing "experimental" add-on, FWP+: Add Attribution; I've decided that it's been enough years, and I've had enough requests, that the Add Attribution feature may as well be included in the main FeedWordPress code.
114
115 Back when FeedWordPress was first created, the assumption was that a well-behaved aggregator would include boilerplate text to indicate the source of syndicated posts, but that the best way to do this was to provide a set of syndication-specific template tags so that the administrator setting up the site could edit their Theme template files with constructs like:
116
117 <?php if (is_syndicated()) : ?>
118 <p class="byline">This post by <?php the_author(); ?> originally
119 appeared at <a href="<?php the_syndication_source_link(); ?>"><?php
120 the_syndication_source(); ?></a>.</p>
121 <?php else : ?>
122 <p class="byline">By <?php the_author(); ?>.</p>
123 <?php endif; ?>
124
125 You can still do this, of course, and for maximum expressive power and flexibility, it is certainly the best way to do it. Template Tags are documented here: <http://feedwordpress.radgeek.com/wiki/templates/> However, (1) it requires writing PHP code, which not everyone is comfortable doing; and (2) it requires altering template files within your Theme, which is not always possible, especially given the increasing role that prepackaged commercial themes have come to play in the WordPress ecosystem. So, now, you can get some basic features for adding boilerplate text and attribution credits even without touching your template files, and without having to add custom add-ons for FeedWordPress. Enjoy!
126
127 * MINOR CODE MODERNIZATION, PHP 7.1 COMPATIBILITY AND BUG FIXES. This project is now 12+ years old (good lord), and there are still some places where code was written at a time when PHP was a very different language from what it is now. Props to @david-robinson-practiceweb for pointing out and sending a pull request to fix some instances where obsolete PHP reference notation (`&$q` on parameters and so on) created a compatibility problem for PHP 7.1. Props to an email correspondent for pointing out a place in SyndicatedPost where excerpts should be generated from post content using encoding-aware mb_substr(), instead of naively running them through substr(). I've begun making some efforts throughout to begin auditing some of the creakiest old code in the project, to update what needs updating and improve documentation throughout.
128
129 = 2017.0913 =
130
131 * PARTIAL FIX FOR 2X DUPLICATE POSTS APPEARING ON DUAL HTTP/HTTPS SITES: Some users reported an issue in which their FeedWordPress sites, which are over both insecure HTTP and over HTTPS, would pick up exactly 2 copies of every post or almost every post from certain feeds, and where the guids for each of the pair of duplicate posts would look exactly alike, except for a difference in the protocol, for example:
132
133 http://www.example.com/?guid=c1cd28da39e8d7babcf6499983aca545
134 https://www.example.com/?guid=c1cd28da39e8d7babcf6499983aca545
135
136 ... where www.example.com is the server that your own copy of FeedWordPress is installed. This release of FeedWordPress normalizes post guid prefixes so as to avoid or limit the scope of this problem.
137
138 * PHP 7 Compatibility: eliminate remaining sources of PHP 7 compatibility-check failures -- remove the use of depreciated mysql_error() function, and make sure all classes make use of __construct() convention for constructors.
139
140 * AVOID "PHP Warning: shell_exec() has been disabled for security reasons in [...]/feedwordpress/feeds-page.php on line 197": FeedWordPress uses the PHP shell_exec() function in a very narrowly limited way for information gathering, trying to find the real path to curl or wget on your system, so that it can give as realistic as possible a recommendation for the sample crontab line displayed in Syndication > Feeds & Updates. Some web hosting environments disable shell_exec for security reasons (since it could in theory be used to do a lot more stuff than the very limited information gathering FWP uses it for); in which case, this part of the code in FeedWordPress could spit out a nasty-looking and potentially worrisome-looking error message. So, now this code is fenced with checks to make sure that shell_exec is available, before FWP attempts to make use of it.
141
142 = 2016.1213 =
143
144 * WORDPRESS BACKWARD COMPATIBILITY FOR VERSIONS [4.5, 4.7]: This change fixes a fatal PHP error (on some web server configurations you'd see the message "Fatal error: require_once(): Failed opening required '[...]/wp-includes/class-wp-feed-cache.php'" on others, you might just see an HTTP 500 Internal Server Error or a blank page) when using FeedWordPress with versions of WordPress before 4.7. A change that I introduced to avoid a code module that had been deprecated in version 4.7 ended up relying on code modules that were only introduced as of version 4.7; so now, instead, FeedWordPress attempts to detect which modules the current version of the WordPress core makes available, and load the right modules depending on your WordPress version.
145
146 In theory, up to this point, FeedWordPress supported any version of WordPress from version 3.0 onward. In practice, version 3.0 was released over 6 years ago, and I can realistically commit only to testing out new releases of FeedWordPress with a few prior versions of WordPress; so I've updated the "Requires at least" field to version 4.5, the first major release issued in 2016. If you've really got to use FeedWordPress with older versions of WordPress, it will probably still work with any moderately modern release of WordPress, but I won't promise to keep it working with releases of WordPress that are more than about a year old.
147
148 = 2016.1211 =
149
150 * WORDPRESS COMPATIBILITY: Tested with new versions of WordPress up to 4.7.
151
152 * PHP WARNINGS UNDER WP 4.7: Eliminated cause of a PHP warning under WP 4.7 "Parameter 1 to FeedWordPressHTTPAuthenticator::set_auth_options expected to be reference" Warnings were due to a change in how http_api_curl hook is sometimes called in WP 4.7; so I changed the signature of the event handling method to avoid the notice. Props to @cogdog, @froomkin, @gwynethllewelyn et al. for flagging the issue and @garymarkfuller for suggesting a preliminary fix to the issue that was fairly similar to the solution I ended up adopting.
153
154 * PHP 7 and PHP Strict Standards compatibility changes: @alexiskulash @daidais and @zoul0813 all sent pull requests through Github to fix some issues from a very old code base that has made its way from PHP 3.x through 5.x to the roll-out of PHP 7. Class methods should now fare better under modern versions of PHP and generate fewer "Deprecated" notices.
155
156 * IMPROVEMENTS TO SCHEDULED AND AUTOMATIC UPDATES: use wp_loaded hook to check for magic URL parameters and to execute updates, to do pageload-based automatic updates, etc. Ensures that anything plugins or themes need to do in init to set up custom post types, taxonomies, etc. will be done before the update_feedwordpress updates are attempted. If you saw posts not getting put into the correct custom post type or custom taxonomies or similar problems when performing scheduled updates, but the problem seemed to go away when you manually performed updates through the wp-admin interface, then you might be able to solve those problems with this update.
157
158 = 2016.0420 =
159
160 * WORDPRESS COMPATIBILITY: Tested with new versions of WordPress up to 4.5.
161
162 * FILTERS AND ADD-ONS: Allow filters and add-ons to filter terms and taxonomy (categories, tags, custom taxonomies, etc.) more thoroughly and more fine-grainedly using syndicated_post_terms_match, syndicated_post_terms_match_{taxonomy}, syndicated_post_terms_unfamiliar, syndicated_post_terms_mapping, syndicated_item_feed_terms, and syndicated_item_preset_terms filters.
163
164 * FILTERS AND ADD-ONS: Globals $fwp_channel and $fwp_feedmeta REMOVED. These global variables, originally introduced to allow filters access to information about the source feed in `syndicated_item` filters were deprecated 6+ years ago. If you have any filters or add-ons which still depend on these global variables, you've been using obsolete techniques and you should see about fixing them to access data about the source feed using the SyndicatedPost::link element instead. For documentation, see the FeedWordPress documentation wiki at <http://feedwordpress.radgeek.com/wiki/syndicatedpost> and <http://feedwordpress.radgeek.com/wiki/syndicatedlink>.
165
166 * BUGFIX: Syndication > Diagnostics HTTP diagnostic test widget was broken due to a dumb error on my part. Now fixed.
167
168 * SMALL CODING CHANGES: Lots of small changes to code organization, incorporation of some PHP 5.x coding conventions, etc.
169
170 = 2015.0514 =
171
172 * IMPORTANT SECURITY UPDATE: This version includes two important fixes for potential security vulnerabilities reported to me through support channels.
173
174 The first is a common problem across several plugins due to an ambiguity in the WordPress documentation and a change in the behavior of WordPress's built-in add_query_arg() and remove_query_arg() functions which could, under certain low-probability conditions, allow for potential XSS attack vectors. This fixes issue # 39 reported at <https://github.com/radgeek/feedwordpress/issues/39> Thanks to github.com/quassy
175
176 The second fixes a security vulnerability that was reported to me privately (thanks to Adrián M. F.) which, under other low-probability conditions, could allow for SQL insertion attacks by a malicious user with access to login credentials, which would compromise data security.
177
178 It is *IMPORTANT* and worth your while to upgrade FeedWordPress as soon as possible in order to eliminate these vulnerabilities. If you have any questions or if there is something blocking you from making the upgrade which you need my help with, don't hesitate to get in touch.
179
180 * ADMIN UI BUGFIX: "Update Now" button in feeds setting pages should now work once again instead of causing a PHP fatal error. See <https://github.com/radgeek/feedwordpress/issues/46>
181
182 * SEVERAL OTHER SMALL BUG FIXES. See <https://github.com/radgeek/feedwordpress/issues/32> <https://github.com/radgeek/feedwordpress/issues/30> <https://github.com/radgeek/feedwordpress/issues/29> etc.
183
184 = 2014.0805 =
185
186 * FILTERS AND ADD-ONS: A number of new hooks for filters and add-ons to further customize the behavior of FWP have been added.
187
188 * COMPATIBILITY/BUGFIX: Many users saw odd characters, especially "n," appearing in posts in versions of WordPress from 3.6 on, due to a change in when the API expects HTML data for posts to be slashed and when it does not. This has been fixed, so that the junk characters should no longer appear, regardless of your version of WordPress.
189
190 * BUGFIX: A bug preventing FWP from saving categories assigned under Syndication > Categories & Tags has been fixed.
191
192 * BUGFIX: Post-editing related metaboxes should now show up when you edit items of any post type, including custom types, not only normal WordPress posts.
193
194 * BUGFIX: A bug in the admin UI that caused the "Alternative Feeds" / "Find Feeds" box to throw a permissions error has been fixed.
195
196 * BUGFIX: A bug preventing proper mapping of categories and other terms in 2013.0504 has been fixed.
197
198 * BUGFIX: A number of small fixes contributed through Github by Flynsarmy should eliminate PHP warnings for many users on several methods that are called as static methods within FeedWordPress.
199
200 = 2013.0504 =
201
202 * BUGFIX: PHP 5.4 compatibility -- includes some more extensive fixes to compatibility issues with PHP 5.4's handling of global variables
203
204 * DIAGNOSTICS: New diagnostics settings added to help track behavior of terms (categories, post tags, etc.) for syndicated posts.
205
206 = 2012.0504 =
207
208 * MODULE REORGANIZATION: Should ensure that all needed submodules will be properly included regardless of whether you are installing from github, from SVN, or from the WordPress plugins page. If you've been getting fatal errors about required modules not being found, this release should hopefully resolve the issue.
209
210 = 2012.0503 =
211
212 * BUGFIX: Works properly again with WordPress installations that use a MySQL table name prefix other than the default `wp_` prefix.
213
214 * BUGFIX: Includes a couple of significant PHP 5.4 compatibility fixes. Now that PHP 5.4 is more widely deployed, Diagnostics will now also show PHP version and some other potentially useful troubleshooting information.
215
216 * ADMIN UI: Better indicates your options when deleting a syndicated post so as to let you know whether it will be Trashed (and thus not resyndicated) or Erased (and thus potentially resyndicated)
217
218 * ADMIN UI: Adds an AJAXy Test Expression button to allow live testing of sample results from expressions in Custom Post Settings.
219
220 = 2012.1218 =
221
222 * WORDPRESS VISUAL EDITOR FIXED. There was an unlisted change in the 2012.1212 release which had the effect of disabling the WordPress Visual Editor for all posts syndicated by FeedWordPress. Many users reported this as a bug. It was actually a deliberate decision -- a crappy way to try to deal with a crappy situation. (Many users had previously reported a "bug" in which all the paragraph or line breaks seemed to be stripped out of their syndicated posts; the issue turned out to be that the Visual Editor was stripping out `<p>` and `<br/>` tags on the assumption that the resulting post would be sent through standard WordPress formatting filters. But under default settings, posts syndicated by FWP deliberately bypass WordPress formatting filters.) In any case, this version adopts a more flexible compromise. *If* FeedWordPress is set up to bypass WordPress formatting filters (as it is by default), *then* the Visual Editor will be disabled for syndicated posts (since using it would produce incorrect results). If on the other hand FeedWordPress is set up to expose syndicated posts to WordPress formatting filters (as it usually is for those using the Visual Editor to manually edit posts), then the Visual Editor tab will be re-enabled for syndicated posts.
223
224 * BUG FIX: PERMALINKS REWRITTEN FOR CUSTOM POST TYPES AS WELL AS NORMAL
225 WORDPRESS POSTS. If you had WordPress set up to syndicate incoming posts
226 to a custom post type (under Syndication > Posts & Links), and asked
227 FeedWordPress to make "permalinks point to the original site", then
228 previous versions of FeedWordPress would fail to do the rewriting --
229 permalinks would only be rewritten to point to the original source for
230 normal WordPress posts, not for custom post types. In 2012.1218 this bug
231 has been fixed: all post types will now have permalinks rewritten unless
232 you request for permalinks to point to the local copy on your aggregator
233 site.
234
235 * BUG FIX: ELIMINATES "PHP Fatal error: Call to a member function
236 setting() on a non-object...." Some changes to the in-memory caching of
237 information about feed subscriptions could result in a fatal PHP error
238 in cases where you have de-activated one of your subscriptions, but
239 posts from that subscription were still in the archive. This would
240 normally show up through half-completed feeds or half-completed pages
241 that suddenly broke off in the middle, and displayed or logged an error
242 message like: "PHP Fatal error: Call to a member function setting() on a
243 non-object in {...}/wp-content/plugins/feedwordpress/feedwordpress.php
244 on line 615". This bug has been eliminated, so affected feeds and pages
245 should now render correctly, and the error message should no longer
246 appear.
247
248 * BUG FIX: CATEGORY BOXES IN SYNDICATION > CATEGORIES & TAGS. Some minor
249 bugs in the appearance and animation of category checkboxes (for
250 example, the checkbox used to select categories for syndicated posts on
251 the Syndication > Categories & Tags settings page) have been fixed.
252
253 = 2012.1212 =
254
255 * WORDPRESS 3.5 COMPATIBILITY: This release has been tested for compatibility
256 with new releases of WordPress, up to version 3.5, and any documented
257 compatibility issues have been cleared -- in particular, if you were seeing
258 error pages stating that you don't have permission to access the
259 FeedWordPress Syndication page within the WordPress admin interface, then
260 upgrading to this release should fix the problem.
261
262 As always, if you encounter any compatibility problems after upgrading your
263 version of WordPress and your version of FeedWordPress to the most recent
264 versions, please contact me with as detailed a description as possible of
265 the issue you are encountering, the circumstances you're encountering it
266 under, what you expect to see happening, and what is happening instead.
267
268 * PHP 5.4 COMPATIBILITY: This release has been audited to fix potential
269 problems with deprecation notices or fatal errors under recent versions
270 of PHP. In particular, all uses of run-time pass-by-reference have been
271 eliminated from the code; if you were seeing a fatal error reading
272 "Call-time pass-by-reference has been removed ..." then upgrading to
273 this release should fix the problem.
274
275 * CUSTOMIZATION FRAMEWORK: A great deal of work has been done to make the
276 underlying framework more flexible, so that PHP add-ons can be written
277 to adapt FeedWordPress to handle custom XML vocabularies, expiration of
278 posts under specified conditions, and other custom behavior.
279
280 * BUGFIX: MANUALLY EDITED POST SLUGS NOT OVERWRITTEN. Thanks to a report
281 by Chris Fritz, I've identified some code that causes post slugs for the
282 posts generated by FWP to be rewritten with every update, even if the
283 user has manually updated the slug from within the WordPress editing
284 interface. This has been fixed: FWP will continue to generate new slugs
285 for syndicated posts, but when syndicated posts are updated, they will
286 retain the slug that they had at the time of the update; any manual
287 changes to the post slug should be preserved.
288
289 * USER-AGENT STRING: FeedWordPress now sends a distinctive User-Agent
290 string identifying itself, and noting that it is a feed aggregator.
291
292 * MISCELLANEOUS PERFORMANCE IMPROVEMENTS: A number of changes have been
293 made to try to reduce the intensity and expense in terms of both
294 database performance and web server memory consumption.
295
296 * DIAGNOSTICS IMPROVEMENTS: A number of new and improved diagnostics have
297 been added which should aid in understanding and troubleshooting issues
298 that may arise.

300 = 2011.1019 =
301
302 * BUGFIX: "THERE ARE NO HTTP TRANSPORTS AVAILABLE" ERROR FIXED: The initial
303 support for HTTP Basic and Digest authentication in version 2011.1018
304 contained a bug that could cause HTTP requests for feeds or for other
305 WordPress resources to break down if you do not have the PHP curl module
306 installed. This bug has been fixed, and these errors should no longer
307 appear.
308
309 * IMPROVED HTTP AUTHENTICATION SUPPORT: In addition, the HTTP Authentication
310 support in FeedWordPress has been extended, to ensure that Basic
311 authentication is available in many web host configurations, and to allow
312 you to add a username and password for a feed immediately when you
313 subscribe to it.
314
315 = 2011.1018 =
316
317 * HTTP BASIC AND DIGEST AUTHENTICATION SUPPORT: FeedWordPress now offers
318 improved support for syndicating feeds that make use of HTTP Basic or HTTP
319 Digest authentication methods. In order to set up authentication on one of
320 your feeds, just go to its Settings > Feed page, and click on the "Uses
321 Username/Password" link underneath the Feed URL. Enter the username and
322 password for accessing the feed, then select the authentication method. (If
323 you're not sure which method your feed provider uses, try Basic first.)
324 Save Changes, and syndicate away.
325
326 NOTE: HTTP Digest support requires the curl module for PHP. If you are not
327 sure whether this module has been installed, contact your web hosting
328 provider to check.
329
330 * WP 3.3 (BETA) COMPATIBILITY: This version fixes an init-sequence bug that
331 could cause intrusive warning messages or fatal errors in WP 3.3 beta
332 versions.
333
334 * BUGFIX: FIXES LONG DELAYS IN UPDATES SCHEDULES IN LARGE INSTALLATIONS. A
335 performance feature introduced in version 2011.0721 had some flaws in its
336 implementation, which tended to create serious delays (on the order of
337 several hours) in FeedWordPress's attempts to schedule updates for feeds,
338 when users had a very large number of feeds (several dozen or more) in their
339 FeedWordPress installation. This feature has been reconfigured to adjust
340 dynamically to the number of feeds in Syndicated Sources and the frequency
341 with which they are updated. If you've seen a lot of ready-to-update feeds
342 piling up, several hours after they were supposed to get updated, then this
343 upgrade should better ensure that your feeds get updated in a timely fashion.
344
345 * BUGFIX: syndicated_item_guid FILTERS FIXED. Previous versions of
346 FeedWordPress theoretically allowed for filters on the syndicated_item_guid
347 hook, which was intended to filter the globally-unique identifier element
348 (rss:guid or atom:id) -- useful if you need to convince FeedWordPress to use
349 different guids, or to recognize two or more incoming posts as versions of
350 the same post rather than as distinct items. However, while the hook
351 affected the guid stored in the WordPress database, it did not affect the
352 guid used to check whether an incoming feed item had already been syndicated
353 or was a new item -- which greatly limited the practical usefulness of the
354 filter. This bug has been fixed: syndicated_item_guid filters should now
355 properly control not only the final database record, but also the initial
356 uniqueness test applied to posts.
357
358 = 2011.0721 =
359
360 * BUGFIX: SERIOUS BUG CAUSING RARE UNEXPECTED DELETION OF PAGES AND OTHER
361 CONTENT. A bug in the guid-checking code for some rare kinds of guids could
362 cause content in the wp_posts table to seemingly disappear at random after
363 FeedWordPress updates.This most frequently but not exclusively affected
364 static pages. What actually happened is that in these rare cases the
365 existing static page was mistaken for an older version of the new incoming
366 syndicated post, which was then stored as a new revision of the original
367 page. The bug that caused these mistaken identities has been fixed.
368
369 * BUGFIX: UNWANTED AUTOMATIC PAGE-LOAD-BASED UPDATES NO LONGER A NUISANCE.
370 Some users encountered a bug in which FeedWordPress would adopt an automatic
371 page-load-based update method, even if they had requested that it not do
372 so, and that it use a manual or cron job update method instead. The bug
373 causing this has been fixed, and page-load-based updates should no longer
374 trigger unless explicitly turned on.
375
376 * WP 3.2 USER INTERFACE COMPATIBILITY: POST TAGS BOX NOW WORKS AGAIN. The
377 release of WordPress 3.2 caused a breakage in the tags box which prevented
378 you from adding or removing tags under Syndication --> Categories & Tags.
379 (The breakage was the result of an incompatibility introduced by the new
380 release of jQuery.) This breakage has now been fixed, and the tags box
381 should work correctly again.
382
383 * FEED UPDATE SCHEDULING IMPROVEMENTS: UI. The Syndicated Sources table now
384 provides considerably more data to understand update scheduling, when
385 specific scheduling decisions are made because of, e.g., requests from the
386 feed producer.
387
388 * FEED UPDATE SCHEDULING IMPROVEMENTS: ENFORCEABLE "MINIMUM INTERVAL" SETTING
389 TO SPACE OUT UPDATES. Some feeds request specific update schedules, using
390 standard elements such as sy:updateFrequency and rss:ttl. Normally,
391 FeedWordPress respects any scheduling requests that a feed makes -- if it
392 requests a longer gap between polls than what FWP would normally adopt, then
393 FWP slows down to meet the request. If it indicates a shorter gap than what
394 FWP would normally adopt, FWP speeds up and checks that feed for updates
395 more often than it normally would. Now, there should not be any way for user
396 settings to override an explicit slow-down request from the feed producer --
397 if producers indicate a particular update schedule, then polling the feed
398 more frequently than they request is considered abusive behavior. But
399 there's no reason why users should not be able -- if they so desire -- to
400 override speed-up requests, and poll a feed *less* frequently than the
401 indicated update schedule, if the FWP user wants to space update checkins
402 over a longer interval of time. Before, they could not do this: FWP always
403 sped up to meet the indicated update schedule. Now, they can do this, by
404 using the new "Minimum Interval" setting in Syndication --> Feeds &
405 Updates..
406
407 = 2011.0706 =
408
409 * WP 3.2 COMPATIBILITY: ELIMINATES FATAL ERROR "Call to undefined method
410 WP_SimplePie_File::WP_SimplePie_File() in
411 [...]/wp-content/plugins/feedwordpress/feedwordpress.php on line 1841." The
412 latest release of WordPress, version 3.2, has shifted the minimum
413 requirements up to PHP 5.2, and in line with the shift to PHP5 they have
414 rewritten a number of code segments that made use of now-obsolete PHP4
415 idioms. Unfortunately, this caused a fatal error whenever FeedWordPress
416 attempted to make use of the cache, since FWP's caching plugin was written
417 to match the older idiom. FeedWordPress has been updated to follow the new,
418 PHP5 idiom when possible, thus eliminating the fatal error.
419
420 * PERFORMANCE: The handling of queries to determine whether posts had been
421 previously syndicated produced some very slow queries (usually, but not
422 always, involving a scan over the MD5(post_guid) column of the table). The
423 code that prepares MySQL queries for previously-syndicated checks has been
424 revised to eliminate the MD5(post_guid) scan entirely, and to significantly
425 improve performance by eliminating other unnecessary clauses.
426
427 * BUGFIX: NO LONGER DESTROYS STICKY POSTS. Previous versions could destroy
428 (or, more precisely, replace the content of) sticky posts due to some
429 queries mashed together in unexpected ways by WordPress. Version 2011.0706
430 accounts for and eliminates the problem; your sticky posts should be safe
431 once again.
432
433 * BUGFIX: GUIDS CONTAINING MYSQL-ESCAPED CHARACTERS NO LONGER CAUSE DUPLICATE
434 POSTS TO APPEAR. One remaining source of duplicate post issues in 2011.0602
435 was guids that contained characters that needed to be escaped for MySQL,
436 such as single quotes and double quotes. The work-around for handling
437 filtered URIs has now been corrected to ensure that these do not cause
438 duplicate posts.
439
440 = 2011.0602 =
441
442 * WP 3.1.3 COMPAT / BUGFIX: WHITESPACE IN GUIDS NO LONGER PRODUCES DUPLICATE
443 POSTS. The work-around for handling filtered URIs in guid elements has now
444 been extended to handle URIs that were filtered because of leading or
445 trailing whitespace, in addition to URIs that were filtered because of
446 unapproved schemes.
447
448 * WP 3.1.3 COMPAT / BUGFIX: RELATIVE URLS IN GUIDS NO LONGER PRODUCE DUPLICATE
449 POSTS. The work-around for handling filtered URIs in guid elements has now
450 been extended to handle URIs that were altered without being filtered out
451 entirely (most commonly because a scheme was added to a relative URL).
452
453 * BUGFIX: UPDATES TO POST NO LONGER CAUSE DUPLICATE DRAFT VERSION TO APPEAR.
454 Under certain conditions in 2011.0531, an update to an existing post would
455 not be properly applied to the post itself, but rather would appear as a
456 duplicate post with Draft status. This bug has been eliminated, and updates
457 will now be properly inserted as revisions to the existing post.
458
459 = 2011.0531 =
460
461 * WORDPRESS 3.1.3 COMPATIBILITY: DUPLICATE POSTS ISSUE FIXED. Due to
462 internal changes in the way that WordPress handles post guids in the
463 most recent release (3.1.3), many users experienced problems with many
464 duplicate posts appearing in rapid succession. (Specifically, this would
465 happen with any posts using tag: URL guids -- such as all the posts
466 coming from Blogger feeds or feeds from other Google services.) This
467 compatibility release of FeedWordPress eliminates the issue by working
468 around the new restrictions on tag: URLs.
469
470 * NEW AND IMPROVED DIAGNOSTICS: Syndication --> Diagnostics now contains some
471 new diagnostics settings useful for debugging problems with duplicate posts
472 (allowing you to easily view the guid of posts in the WordPress posts
473 database and allowing you to track the SQL used to check for existing
474 versions of a syndicated post).
475
476 = 2011.0512 =
477
478 * DIAGNOSTICS IMPROVEMENTS; "THERE MAY BE A BUG IN FEEDWORDPRESS" CRITICAL
479 ERROR NOTICES ELIMINATED: This version includes some major improvements
480 to the Syndication --> Diagnostics section, which should aid in
481 troubleshooting difficulties with items failing to be imported, posts
482 failing to be properly inserted into the database, or updates failing to
483 be recorded. If you have been encountering critical error / bug notices
484 with a white screen and the message "THERE MAY BE A BUG IN
485 FEEDWORDPRESS," followed by an extraordinarily long dump of mostly
486 incomprehensible diagnostic information, you'll be happy to know that
487 the condition causing these notices has been eliminated. In the few
488 cases where errors may still crop up with database insertions,
489 FeedWordPress will now produce a significantly more manageable and more
490 useful diagnostic message.
491
492 * BUGFIX: NEW POSTS FAILING TO APPEAR IN A CLEANLY-INSTALLED FEEDWORDPRESS
493 SYSTEM. If you encountered a recurring problem with FeedWordPress
494 failing to import new posts, after a clean install of FeedWordPress
495 (i.e., not an upgrade from a previous version), this problem may have
496 been the result of a bug with author-handling which has now been fixed
497 in the 2011.0512 release. (If the problem does *not* go away with the
498 upgrade, this version also includes significant improvements to the
499 Diagnostics system, which will help track down what *is* causing it
500 in your particular case.)
501
502 * PERFORMANCE: New handling of update hashes allows FeedWordPress to avoid
503 a certain kind of infinite loop, caused when two more more different
504 syndicated feeds each carried a version of the same item (for example,
505 because it appeared on two different aggregator feeds that you're
506 syndicating). In previous versions, when this kind of loop cropped up,
507 syndicated posts could pile up an indefinitely large number of revisions
508 -- each revision alternating between the version from each of the two
509 feeds where it appeared -- which would, over time, dramatically inflate
510 the size of the database, and kill the performance of queries on the
511 post table. This issue has been resolved: revisions of the post that
512 have been syndicated once will not be re-syndicated over and over again.
513
514 * AUTHOR LISTS: Lists of authors presented on the Author settings pages
515 should now be easier to scan through, with author names arranged in
516 alphabetical order.
517
518 * FEED ITEM DATE PARSING: More tweaks to make date-time handling more
519 resilient when feeds provide broken or weird values for the timestamps
520 on syndicated items. FWP will now attempt to work around unparseable
521 timezone values.
522
523 * AUTHOR MATCHING: Now attempts to match author names against the WP login
524 name in addition to display_name; when creating user record, also fills
525 in some best-guess values for nickname, firstname and lastname. Also
526 properly picks up Atom 1.0 author/uri data from feed.
527
528 * COMPATIBILITY: FeedWordPress has been successfully tested for
529 compatibility with recent releases of WordPress, up to version 3.1.2.
530
531 = 2011.0211 =
532
533 * BUGFIX: DUPLICATE POSTS WHEN GUIDS ARE TOO LONG: When feeds included
534 exceptionally long GUIDs, FeedWordPress could occasionally get into
535 a situation where posts with the long GUIDs would be duplicated over
536 and over again with each update (because FWP failed to store the full
537 GUID, due to length constraints in the relevant database tables).
538 Without the full GUID, FWP would not know that the post had already
539 been syndicated once. This bug has been fixed, and should no longer
540 produce duplicate posts.
541
542 * HTTP TIMEOUT SETTING: If you are frequently running into timeout
543 problems with one or more of the feeds you syndicate, FWP now allows you
544 to adjust the timeout for HTTP requests using a global or feed-by-feed
545 setting.
546
547 * HTTP GET PARAMETERS: You can now temporarily or permanently add HTTP
548 GET parameters to a subscription using an interface in Syndication -->
549 Feeds & Updates. This is especially helpful for making quick, short-term
550 changes to a subscription (for example, to pull in all the previous
551 items from a web service, before settling down to pulling in only newly
552 updated items).
553
554 * DIAGNOSTICS SYSTEM: Added several new diagnostics which are useful in
555 troubleshooting, and established a framework for add-on modules to hook
556 in with their own diagnostic messages.
557
558 * UI: Adjusted some internal coding, which should allow for settings
559 pages and add-ons to properly display multiple category pickers on a
560 single settings page.
561
562 * PHP4 COMPATIBILITY TWEAKS: This version makes some tweaks to the handling
563 of object references which should improve compatibility with older
564 versions of PHP. (Although, I should note, web hosts that still force
565 you to run under PHP 4 -- in 2011! -- are *bad web hosts*.)
566
567 * IMPROVED PERFORMANCE: This version eliminates a *major* performance drag
568 that shows up on sites with large numbers of users (due to some poor
569 decisions about where to place a user query, which caused the user table
570 to be scanned frequently when it did not need to be). If you experienced
571 serious problems with CPU load or slow database performance under
572 2010.0905, which kicked in immediately when FWP was loaded and tended
573 to disappear immediately if FWP was de-activated, it is likely that
574 upgrading away from 2010.0905 to the most recent version will resolve
575 your problem.
576
577
578 = 2010.0905 =
579
580 * BUGFIX: CATEGORIES AND TAGS CORRECTLY ASSIGNED IN AUTOMATIC UPDATES.
581 Version 2010.0903 switched over to a new way of assigning categories and
582 tags as part of its support for handling custom taxonomies.
583 Unfortunately, the method that it uses is subjected to some checks of
584 the current user's capabilities, which creates problems for posts that
585 are being inserted into the WordPress database when there *is* no
586 current user logged in (as, for example, when an update is being carried
587 out from a cron job or automatic update). The result was that posts
588 from cron jobs and automatic updates ended up with no Categories and no
589 Tags being assigned. This bug has now been fixed: in 2010.0905, Tags and
590 Categories should be correctly assigned to all posts, regardless of
591 whether they were added from manual updates, cron jobs, or automatic
592 updates.
593
594 = 2010.0903 =
595
596 * WORDPRESS 3 REQUIRED: Please note that this release of FeedWordPress
597 *requires* WordPress 3.0 or later. If you are currently using a 2.x
598 branch of WordPress, you will need to upgrade to WordPress 3 before you
599 can successfully upgrade FeedWordPress.
600
601 * BUGFIX: NO MORE DISAPPEARING "SYNDICATED SOURCES" PANEL; INTERNET
602 EXPLORER UI GLITCH APPARENTLY FIXED: Several users independently
603 reported a problem with FWP 2010.0623 and various versions of IE. A
604 problem with the HTML markup caused IE (but not Firefox or
605 Chrome) to completely hide the Syndicated Sources administration panel
606 (the main list of currently-syndicated sources, and the main location
607 for adding new sources, under the Syndication menu item) when a user
608 added their first syndicated feed. Maddeningly, the glitch seemed to
609 affect some IE users and not others: I was never able to reproduce the
610 problem for myself on my own machines. However, the markup of Syndicated
611 Sources has undergone significant changes and corrections since
612 2010.0623, and two independent sources who had been having this problem
613 confirm that they no longer encounter it with the updated version. For
614 the time being, I am going to declare this bug squashed.
615
616 * BUGFIX: MORE PROTECTION AGAINST FATAL ERRORS FROM PLUGGABLE VERSIONS OF
617 SimplePie: FeedWordPress now takes some precautions that should help to
618 better avoid conflicts for users who have installed pluggable versions
619 of SimplePie for another plugin or theme. (You may not know that you have
620 done this; but if you've been encountering fatal errors indicating that
621 you cannot redeclare class SimplePie, or something along those lines,
622 there is now a better chance that those fatal errors will be eliminated.
623
624 * PERFORMANCE: SIGNIFICANTLY REDUCED MEMORY CONSUMPTION FOR LARGE UPDATES:
625 FeedWordPress is still a memory-hungry little module, especially when
626 you are dealing with very large feeds. However, users should notice a
627 significant reduction in memory overloads, especially if they update a
628 large number of feeds at once.
629
630 * USER INTERFACE IMPROVEMENTS: Nothing is radically different, but there's
631 been a fair amount of extra spit and polish added, including a convenient
632 new Dashboard widget that may save you a trip to the Syndication menu,
633 a lot of effort to make the relationship between global and feed-by-feed
634 settings more obvious to the user and more easily controllable, to make
635 navigation between settings pages easier, to sand off a few rough edges,
636 and to make other improvements on the margins. I hope you'll like how
637 it looks.
638
639 * ADDING MULTIPLE FEEDS: FeedWordPress now provides a convenient mode for
640 adding multiple feeds at once, using either a copy-and-pasted list, or
641 else an OPML file. Go to Syndication --> Syndicated Sources and check
642 out the two new buttons underneath the New Source input box. When you
643 have to add a number of feeds at once, this can save you considerable
644 time and trouble.
645
646 * IMPROVED HANDLING OF AUTHORS WITH DUPLICATE E-MAIL ADDRESS AND AUTHORS
647 WITH NAMES WRITTEN IN FOREIGN SCRIPTS: WordPress 3 is increasingly picky
648 about what it will accept for new author accounts, and some of the
649 conditions it imposes can cause error conditions that prevent posts from
650 being properly syndicated, or properly attributed, if authors happen to
651 have identical e-mail addresses, or if users are given usernames that are
652 written in non-Western scripts. FeedWordPress now handles these much
653 better, and systematically works to avoid clashes between syndicated
654 authors' account names or in their e-mail addresses, which should result
655 in significantly better results in mapping author names to WordPress
656 user accounts.
657
658 * MAPPING CATEGORIES ON SYNDICATED POSTS TO TAGS NOW BETTER SUPPORTED:
659 In previous versions, the only way for the Categories provided by a
660 syndicated feed to be mapped into Post Tags was to instruct FWP to
661 create new tags, rather than new categories, for unfamiliar categories
662 from the feed. This works fine if you want tags to be the default; but
663 if you want only a *specific* set of tags, there was no way to get them
664 without getting most or all other categories imported as tags. You can
665 now do this by creating a tag (under Posts ==> Post Tags) before
666 importing the post; when the syndicated category matches a pre-existing
667 tag, the incoming post will be tagged with that tag, without creating
668 a local Post Category.
669
670 * REL-TAG MICROFORMAT SUPPORT FOR INLINE TAGS: Syndicated posts that
671 contain inline tags, marked up using the Rel-Tag microformat
672 <http://microformats.org/wiki/rel-tag>, are now tagged with the tags
673 provided by Rel-Tag format links.
674
675 * MUCH GREATER CONTROL OVER CATEGORY AND TAG MAPPING: This is partly the
676 result of building in support for a potentially endless set of custom
677 taxonomies (see below), but in general there has been a great deal of
678 effort towards giving you more control over how categories and tags
679 provided by the feed are mapped into terms on the local blog. In
680 particular, you can now force FeedWordPress to create only categories
681 from categories and tags provided by the feed; or to create only tags;
682 or to search both categories and tags for a match; or you can simply
683 force it to drop all of the categories provided by the feed and use
684 only categories or tags that you explicitly provide. In addition, you
685 can now also choose whether to override global categories settings with
686 a local, feed-specific setting; or whether to *add together* *both* the
687 global categories and the local feed-specific categories -- depending
688 on whatever your use-case may demand.
689
690 * CUSTOM POST TYPES AND TAXONOMY SUPPORTS: This is mainly for the
691 super-geeky, but if you use other plugins or themes that make
692 significant use of WordPress's support for custom post types and custom
693 taxonomies, you may be pleased to find that FeedWordPress now allows you
694 to feed incoming posts into any custom feed type that you wish, and to
695 map categories and tags from the feed to custom taxonomies as well as
696 to the standard Category and Tag taxonomies.
697
698 * STORING NAMESPACED CUSTOM FEED ELEMENTS IN POST CUSTOM FIELDS: If you
699 would like to use FeedWordPress's support for storing custom meta-data
700 from feed elements in the custom fields for a post (for example, to
701 store geolocation data or iTunes media meta-data), you'll find that it's
702 now much easier for you to access these namespaced elements. You always
703 could access them, but in previous versions you might have to write
704 something ugly like $(/{http://www.w3.org/2003/01/geo/wgs84_pos#}lat)
705 just to get at the value of a `<geo:lat>` tag. Now, as long as you use
706 the same mnemonic codes that the feed producer used, you should always
707 be able to write a nice, simple expression like $(/geo:lat) to get the
708 value of a <geo:lat> tag.
709
710 * CUSTOM DIRECTORY STRUCTURE SUPPORT: if you poke at it enough, WordPress
711 is relatively flexible about where it should store admin interface code,
712 uploaded content, plugins, and a number of other things that occupy an
713 important place in the WordPress directory structure. Previous versions
714 of FeedWordPress encountered serious errors or broke entirely when used
715 with directory structures other than the default. This should now be
716 fixed: FWP now supports custom directory structures wherever WordPress
717 allows them to be customized, rather than depending on the default
718 locations. Enjoy your freedom!
719
720 * MANY NEW FILTERS AND API UTILITY FUNCTIONS FOR ADD-ON PROGRAMMERS: There
721 have been too many improvements to list them all in this ChangeLog, but
722 it means that much more power and ease for folks who are customizing
723 FeedWordPress through PHP filters or add-on modules. Fuller
724 documentation will be put up at the Wiki at feedwordpress.radgeek.org
725 soon.
726
727 = 2010.0623 =
728
729 * WORDPRESS 3.0 COMPATIBILITY / AUTHOR MAPPING INTERFACE ISSUES: I
730 resolved a couple of outstanding issues with the author mapping
731 interface (Syndication --> Authors), which were preventing new users
732 from being created correctly and author mapping rules from being set up
733 correctly. These partly had to do with new restrictions on user account
734 creation introduced in WordPress 3.0; anyway, they should now be fixed.
735
736 * MORE EFFICIENT SYNDICATED URL LOOKUPS: Several users noticed that the
737 bug fix introduced in 2010.0528 for compatibility with post-listing
738 plugins caused a lot more queries to the database in order to look up
739 numerical post IDs from the URL provided to the filter. This shouldn't
740 cause any major problems, but it is not as efficient as it could be; the
741 code now takes advantage of a more efficient way of doing things,
742 which usually will not require any additional database queries.
743
744 * SIMPLEPIE FEED UPDATE ISSUES: If you have been having significant
745 problems with getting feeds to update correctly, this may be the result
746 of some bugs in the implementation of SimplePie caching that ships with
747 WordPress (as of version 3.0). (You would most commonly experience this
748 error if you continually saw errors such as "No feed found at <...>" in
749 your updates.) Fortunately, SimplePie allows for a great deal of
750 extensibility and this allows me to work around the problem; these
751 error conditions should now be mostly eliminated when the underlying
752 feed is valid.
753
754 * UI: SHOW INACTIVE SOURCES: When you use the default unsubscribe option
755 -- which turns off the subscription to a feed while preserving the posts
756 from it and the syndication-related meta-data for the feed -- the
757 unsubscribed feed can now easily be viewed in a special "Inactive"
758 section of the Syndicated Sources page. (As a side benefit, if you've
759 accidentally, or only temporarily, turned off the subscription to a
760 feed, it is now much easier to restore the feed to being active, or to
761 delete it permanently, if you prefer.
762
763 * UI: FEED FINDER / SWITCH FEED INTERFACE IMPROVEMENTS: changes to styling
764 and options for the feed finder / switch feed, which should now make it
765 easier, in some cases, to find alternative feeds, and make interface
766 options more clearly visible.
767
768 * FILTERS: `syndicated_item_published` and `syndicated_item_updated` NOW
769 PROPERLY AFFECT THE DATING OF POSTS. These filters used to affect some
770 date-related settings, but not others -- and, most importantly, not the
771 final date that is set for a post's publication or last-modified date
772 in the WordPress database. Now, they do affect that, as they should.
773 (Filters should receive, and return, a long integer, representing a Unix
774 epoch relative timestamp.)
775
776 * MAGIC URL TO CLEAR THE CACHE: Suppose that you need to clear the feed
777 cache, for whatever reason; suppose, even, that you need to clear it on
778 a regular basis. One way you might do this is by logging into the
779 FeedWordPress administrative interface and going to Syndication -->
780 Performance. Another way you might do it, now, is to simply send an
781 HTTP request to a magic URL provided by FeedWordPress: if your blog is
782 at example.com, the URL would be <http://example.com/?clear_cache=1>
783
784 = 2010.0602 =
785
786 * CATEGORY BOX INTERFACE ELEMENT FIXED FOR WP 3.0: Stylesheet changes
787 between WordPress 2.9.x and the WordPress 3.0 RC caused the Categories
788 box under **Syndication --> Categories & Tags** to malfunction. This
789 has been fixed.
790
791 * LINK CATEGORY SELECTION BOX IN SYNDICATION ==> FEEDS FIXED FOR WP 2.8
792 AND 2.9: A WP 3.0 compatibility change introduced in 2010.0531
793 inadvertently broke the Syndicated Link Category selector under
794 Syndication --> Feeds & Updates in WP 2.8 and WP 2.9, causing the post
795 categories to be displayed in the selector rather than the link
796 categories. This should now be fixed so that the selector will work
797 correctly under both the current versions of WordPress and the 3.0 RC.
798
799 * MORE PERMISSIVE HANDLING OF FEEDS WITH BAD CONTENT-TYPE HEADERS: One of
800 the small advantages that MagpieRSS had over SimplePie is that it was
801 more tolerant about parsing well-formed feeds that the remote web server
802 happened to deliver with weird or incorrect HTTP Content-type headers.
803 In feeds affected by this problem, the new SimplePie parser would simply
804 fail to find a feed, due to its being led astray by the contents of the
805 Content-type header. This version includes an extension to SimplePie's
806 content-type sniffer that offers more permissive handling of the HTTP
807 headers.
808
809 * MORE FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Version 2010.0528
810 introduced code to control for cases in which elements intended for
811 item summaries are (ill-advisedly) used to carry the full text of posts;
812 past versions of FeedWordPress would simply include the full text of the
813 post in the excerpt field, but newer versions now attempt to detect
814 this condition when it arises and to head it off, by blanking out the
815 excerpt field and filling it with an automatically generated short,
816 plain text excerpt from the full content. This release broadens the
817 test conditions that indicate when an excerpt field is treated as
818 identical to the full text of the post, and should therefore improve
819 the handling of some feeds (such as Google Reader feeds) where the full
820 text of each post was still appearing in the excerpt field.
821
822 * FILTERS: `syndicated_item_published` AND `syndicated_item_updated`
823 FILTERS NOW ALLOW FILTER AUTHORS TO CHANGE POST TIMESTAMPS. You can now
824 use the `syndicated_item_published` and `syndicated_item_updated` filter
825 hooks to write filters or add-ons which directly change the post date
826 and most-recently-updated timestamps on incoming syndicated posts. Props
827 to niska for pointing out where the filters needed to be applied in
828 order to change WordPress's internal timestamps for incoming posts.
829
830 = 2010.0531 =
831
832 * PERMALINK / CUSTOM FIELDS PROBLEM RESOLVED: An issue in 2010.0528 caused
833 some posts to be imported without the proper syndication-related
834 meta-data being attached (thus causing permalinks to point back to the
835 aggregator website rather than to the source website, among other
836 problems). This problem has been resolved (and a fix has been applied
837 which will resolve the problem for any posts affected by this problem,
838 if the original post is recent enough to still be available on the feed).
839
840 * UI: The "Back End" section has been split into two separate sections --
841 "Performance" (dealing with caching, database index, and other
842 performance tweaks), and "Diagnostics" (dealing with debug mode,
843 update logging, and a number of new diagnostic tests which I will be
844 rolling out over the next few releases).
845
846 * Several minor interface bug fixes and PHP warning notices eliminated.
847
848 = 2010.0528 =
849
850 #### Compatibility ####
851
852 * SIMPLEPIE IS NOW USED TO PARSE FEEDS; NO MORE MAGPIERSS UPGRADES NEEDED:
853 One of the biggest changes in this release is that FeedWordPress no
854 longer depends on MagpieRSS to parse feeds, and has switched to the much
855 more up-to-date and flexible SimplePie feed parser, which is included as
856 a standard part of WordPress versions 2.8 and later. Using SimplePie will
857 hopefully allow for better handling of feeds going further, and will
858 allow me greater flexibility in determining how exactly the feed parser
859 will operate. It also means that FeedWordPress no longer requires
860 special upgrades to the WordPress core MagpieRSS files, and should
861 eliminate quite a bit of complexity.
862
863 * MAGPIERSS COMPATIBILITY LAYER FOR EXISTING FILTERS AND ADD-ONS: However,
864 I have also implemented a compatibility layer to ensure that existing
865 filters and add-ons for FeedWordPress which depended on the MagpieRSS
866 data format *should not be broken* by the switch to SimplePie. Going
867 forward, I recommend that new filters and add-ons be written to take
868 advantage of the SimplePie object representations of items, feeds, etc.,
869 rather than the MagpieRSS arrays, but the MagpieRSS arrays will still
870 be available and older filters should continue to work as they have in
871 the past.
872
873 * COMPATIBILITY WITH WORDPRESS 2.9.x and 3.0: This release has been tested
874 for the existing WordPress 2.9.x branch and with the upcoming release of
875 WordPress 3.0. Changes in the user interface JavaScript between WordPress
876 2.8.x and WordPress 2.9 caused the tag box interface element to break in
877 the Syndication --> Categories & Tags settings page; changes in the API
878 functions for adding new authors caused fatal errors under certain
879 conditions in WordPress 3.0. These breakages have been fixed.
880
881 * DROPPED LEGACY SUPPORT FOR WORDPRESS PRIOR TO 2.8: Because SimplePie is
882 not included with versions of WordPress prior to 2.8, I have chosen to
883 drop legacy support for WordPress versions 1.5 through 2.7. If you are
884 using FeedWordPress with a version of WordPress before 2.8, you will
885 have to upgrade your installation of WordPress in order to take
886 advantage of this release.
887
888 * PHP 5.3 COMPATIBILITY: A couple of compatibility issues, which were
889 causing fatal errors amd ugly warnings for users of PHP 5.3,
890 have been eliminated.
891
892 #### Features and Processing ####
893
894 * INTERFACE REORGANIZATION: The interface restructuring, began with
895 Version 2009.0612, has been completed. Catch-all settings pages have
896 been eliminated entirely for pages that cover each aspect of handling
897 a feed: Feeds & Updates, Posts & Links, Authors, Categories & Tags,
898 and Back End handling of the database and diagnostic information.
899 Extensive new interface hooks allow add-on modules to significantly
900 change or extend the FeedWordPress admin interface and workflow.
901
902 * STORING INFORMATION FROM THE FEED IN CUSTOM FIELDS: Many users
903 have written to request the ability to store information from elements
904 in the feed in a custom field on each post. (So that, for example, if
905 post includes a `itunes:duration` element, you could store the contents
906 in a Custom Field called `duration` on the post (for a Theme to access
907 later). The Custom Post Settings under Syndication --> Posts & Links now
908 allow you to access any item or feed tag, using a syntax similar to
909 a much-simplified version of XPath. See Posts & Links settings for
910 details.
911
912 * UPDATE-FREEZING ON MANUALLY EDITED POSTS: FeedWordPress now allows you
913 to mark posts that have been manually edited, so that the changes you
914 make will not be overwritten by later updates from the feed. If you make
915 manual edits to a particular post, just check the "Manual editing"
916 checkbox in order to protect your changes from being overwritten. If you
917 want to block *all* posts from being updated after they are imported
918 for the first time, a new "Updated Posts" setting in Posts & Links
919 allows you to freeze all posts from a particular feed, or all syndicated
920 posts.
921
922 * SETTING: FEED-BY-FEED SETTINGS FOR WHERE PERMALINKS POINT TO: You've
923 always been able to tell FeedWordPress whether permalinks for posts
924 should point to the original source of the story or the local copy. Now
925 you can choose different policies for different feeds, instead of one
926 global policy for all feeds. (Of course, you can still use a global
927 default if you prefer.)
928
929 * SETTING: USER CONTROL OVER TIMING BASIS. You can now determine the
930 schedule on which feeds are considered ready to poll for updates --
931 by default feeds become ready for polling after about 1 hour. You can
932 now increase or decrease the time window under Syndication --> Feeds &
933 Updates. (However, please pay *CAREFUL ATTENTION* to the recommendations
934 and DO NOT set the scheduling lower than 60 minutes unless you are
935 ABSOLUTELY SURE that you have specific permission from webmaster who
936 provides that specific feed to poll more frequently than that. If you
937 set this too low (and about 60 minutes is the polite minimum if you
938 haven't been given a different figure), most webmasters will consider
939 the frequent hits on their server as rude, or even downright abusive.
940
941 * OTHER SETTINGS: New settings also include the ability to stop FWP from
942 resolving relative URLs within syndicated content, and the ability to
943 choose whether FeedWordPress should indicate the comment feed from the
944 original source, or the local comment feed, when providing the comment
945 feed URL for a syndicated post.
946
947 #### Parsing ####
948
949 * BETTER DATE HANDLING -- FEWER FLASHBACKS TO 1969 and 1970: FeedWordPress
950 has made some bugfixes and some improvements in the logic for parsing
951 dates. This should allow FeedWordPress to correctly parse more dates in
952 more feeds; and, in the last resort, when FeedWordPress fails to
953 correctly parse a date, to fall back to a more intelligent default. This
954 should hopefully avoid most or all error conditions that have resulted
955 in articles being erroneously dated to the dawn of the Unix epoch
956 (31 December 1969 or 1 January 1970).
957
958 * FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Based on a straightforward
959 reading of the existing RSS specs, it's reasonable for the
960 rss:description element to be read as a plaintext summary or excerpt for
961 the item containing the description -- with the full text of the item,
962 if available, in another, better-suited element, such as the de facto
963 standard content:encoded extension element. The problem is that uses of
964 RSS rarely have much to do with anything like a straightforward reading
965 of the specs. As a result, many actual RSS producers in the wild put the
966 full text of the article in a description element. But since
967 FeedWordPress has treated this text as a summary, this produces
968 aggregated posts with lengthy "excerpts" containing the full text of the
969 article. This release of FeedWordPress fixes the problem by doing a
970 little digging before treating rss:description as a summary: if the
971 description element is used properly as a plain text summary, then
972 FeedWordPress will take the summary provided by the feed, rather than
973 recreating its own excerpt from the full text; but if an RSS item has no
974 full-text element other than description, FeedWordPress will treat the
975 description element as the full text of the article, and generate a
976 shortened excerpt automatically from that text.
977
978 #### API ####
979
980 * TEMPLATE API: new template tags `get_local_permalink()` and
981 `the_local_permalink()` allow you to access the permalink for a post on
982 your aggregator site, even when FeedWordPress is rewriting permalinks to
983 point to the original source site.
984
985 * NEW HOOKS FOR ADD-ONS AND FILTERS: I have added a number of new hooks
986 which allow add-on modules to filter more precisely, gather information
987 at more points, and to enhance the FeedWordPress admin interface. For
988 a list of new hooks and documentation, see the FeedWordPress
989 documentation wiki at
990 <http://feedwordpress.radgeek.com/wiki/add-ons-and-filters>
991
992 * FILTER API: A number of new utility methods have been added to the
993 SyndicatedPost class to make it easier for filters and add-ons to
994
995 * FILTER API: Globals $fwp_channel and $fwp_feedmeta DEPRECATED. These
996 global variables, originally introduced to allow filters access to
997 information about the source feed in `syndicated_item` filters (which
998 were passed in through global variables rather than as parameters
999 because of a bug in WP 1.5 which was then fixed in 1.5.1) have been
1000 DEPRECATED. If you have any filters or add-ons which still depend on
1001 these global variables, you should see about fixing them to access data
1002 about the source feed using the SyndicatedPost::link element instead.
1003 For documentation, see the FeedWordPress documentation wiki at
1004 <http://feedwordpress.radgeek.com/wiki/syndicatedpost> and
1005 <http://feedwordpress.radgeek.com/wiki/syndicatedlink>.
1006
1007 * DIAGNOSTICS: I've included a number of new diagnostic options and
1008 messages, which should allow an experienced user to better investigate
1009 any problems that may crop up.
1010
1011 #### Bug Fixes ####
1012
1013 * BUGFIX: & IN PERMALINKS NO LONGER CAUSING ATOM OR HTML VALIDATION
1014 EFFORTS: Many users reported an issue in which syndicating a feed with
1015 special XML characters in the URLs (& was the most common, since it is
1016 used to separate HTTP GET parameters) would cause the aggregator's
1017 feeds to produce invalid (malformed) XML. This update addresses the
1018 issue in Atom feeds. Unfortunately, it has not been technically possible
1019 to address the problem in RSS 2.0 feeds, due to limitations on
1020 WordPress's internal templates for RSS feeds.
1021
1022 * BUGFIX: BROKEN URLS IN "POPULAR POSTS" AND SIMILAR PLUGINS SHOULD NO
1023 LONGER BE BROKEN. A number of users noticed an issue where plugins and
1024 templates that listed posts in locations outside of the post loop
1025 (for example, "Popular Posts"-style plugins that listed posts in the
1026 sidebar), often produced the wrong URL for post links. (Typically, all
1027 the posts listed would get the same wrong URL.) This should now be
1028 fixed. Thanks to Björn for sending in a quick fix!
1029
1030 * MINOR BUGFIXES: This release includes a number of fixes to minor bugs
1031 and compatibility issues, including: silent failures of the "Syndicate"
1032 button, "Illegal Offset Type" error messages from MagpieRSS, and others.
1033
1034 = 2009.0707 =
1035
1036 * BUGFIX: WORDPRESS 2.8 AJAX COMPATIBILITY ISSUES RESOLVED (blank or
1037 truncated "Syndicated Sites" administration page): Due to changes in the
1038 AJAX interface elements between WordPress 2.7 and WordPress 2.8, several
1039 FeedWordPress users encountered an issue where the front "Syndication"
1040 page in the FeedWordPress administrative interface would come up blank,
1041 without the normal "Syndicated Sites" list and "Update" control, or
1042 sometimes wth the boxes visible but one or both of them truncated, with
1043 only the title bar. This issue should now be resolved: with the new
1044 version of FeedWordPress, the compatibility issue that caused the
1045 disappearance should be eliminated, and if boxes are shown with only
1046 their handle visible, you should once again be able to drop down the
1047 rest of the box by clicking once on its title bar.
1048
1049 * BUGFIX: TAG SETTING WIDGET FIXED. Due to changes in interface elements
1050 between WordPress 2.7 and WordPress 2.8, people using FeedWordPress with
1051 WordPress 2.8 found that the widget for setting tags to be applied to
1052 all syndicated posts, or all syndicated posts from a particular feed,
1053 no longer displayed "Add" and "Remove" buttons for individual tags. This
1054 issue has now been fixed, and the tagging widget should once again work
1055 more or less exactly like the tagging widget for individual posts in the
1056 normal WordPress admin interface.
1057
1058 = 2009.0618 =
1059
1060 * BUGFIX: MYSTERY ERRORS WITH WITH WP_Http_Fsockopen HTTP TRANSPORT
1061 ELIMINATED: Thanks to a combination of a subtle bug in FeedWordPress,
1062 and changes to the HTTP transport code in WordPress, a number of users
1063 encountered an error in which any time they attempted to add a new feed
1064 through the FeedFinder interface, FeedWordPress would fail and display
1065 an HTTP request failure diagnostic message. The subtle bug has been
1066 fixed, and with it, most of these errors should now be eliminated.
1067
1068 Be sure to upgrade your MagpieRSS to the most recent MagpieRSS version
1069 after you have insalled FeedWordPress 2009.0618, or this bug fix will
1070 not take effect.
1071
1072 = 2009.0613 =
1073
1074 * INTERFACE/BUGFIX: WORDPRESS 2.8 CATEGORY BOX FIX. Thanks to a subtle
1075 change in class names between the WordPress 2.7 and 2.8 stylesheets,
1076 category boxes in the FeedWordPress settings interface tended to overflow
1077 and have a lot of messy-looking overlapping text under WordPress 2.8.
1078 This has now been fixed.
1079
1080 * FeedFinder FAILURE DIAGNOSTICS: When FWP's FeedFinder fails to find any
1081 feeds at a given URL (for example, when you are trying to add a
1082 subscription through the administrative interface and you run into an
1083 error message), FeedWordPress now provides more diagnostic information
1084 for the reasons behind the failure. If that helps you, great; if not,
1085 it should help me respond more intelligently to your support request..
1086
1087 = 2009.0612 =
1088
1089 * WORDPRESS 2.8 COMPATIBILITY: FeedWordPress 2009.0612 has been tested for
1090 compatibility with the recent version 2.8 release of WordPress.
1091
1092 * INTERFACE RESTRUCTURING: In order to avoid settings posts from becoming
1093 too crowded, and to modularize and better organize the user interface,
1094 new "Posts" and "Categories & Tags" subpages have been created under the
1095 "Syndication" menu. "Posts" controls settings for individal syndicated
1096 posts (such as publication status, comment and ping status, whether or
1097 not to use the original location of the post as the permalink, whether
1098 or not to expose posts to formatting filters, and so on). "Categories &
1099 Tags" controls settings for assigning new syndicated posts to categories
1100 and tags, such as categories or tags to apply to all syndicated posts,
1101 and how to handle categories that do not yet exist in the WordPress
1102 database. These subpages, like the Authors subpage, handle settings for
1103 the global default level and for individual syndicated feeds.
1104
1105 Corresponding to these new subpages, the old Syndication Settings and
1106 Feed Settings subpages have been cleaned up and simplified, and now only
1107 link to the appropriate subpages for options that can be set in the
1108 Posts, Authors, or Categories & Tags subpages.
1109
1110 * FEATURE: ADD CUSTOM SETTINGS TO EACH SYNDICATED POST: FeedWordPress has
1111 long had an interface for creating custom settings for each syndicated
1112 *feed* which could be retrieved in templates using the `get_feed_meta()`
1113 template function. But it had no feature for adding custom fields to
1114 each individual syndicated *post*. In response to requests from users, I
1115 have added the ability to apply custom fields to each individual
1116 syndicated post, using the new Syndication --> Posts subpage. You can
1117 set up custom fields to be applied to every syndicated post, or custom
1118 fields to be applied to syndicated posts from a particular feed.
1119
1120 * FEATURE: MAGPIERSS VERSION CHECK AND UPGRADE: FeedWordPress will attempt
1121 to determine whether or not you are using the upgraded version of
1122 MagpieRSS that comes packaged with FeedWordPress. If not, it will throw
1123 an error on admin pages, and, if you are a site administrator, it will
1124 give you the option to ignore the error message, or to attempt an
1125 automatic upgrade (using a native file copy). If the file copy fails,
1126 FeedWordPress will offer some guidance on how to perform the upgrade
1127 manually.
1128
1129 * BLANK POSTS PROBLEM NO LONGER OCCURS WITH OLD & BUSTED MAGPIERSS: Due
1130 to the fact that I relied on a content normalization that occurs in my
1131 upgraded version of MagpieRSS, but not in the old & busted version of
1132 MagpieRSS that ships with WordPress, until this version, if you tried to
1133 syndicate an Atom feed without having performed the (*strongly
1134 recommended*) MagpieRSS upgrade, all of the posts would come up with
1135 completely blank contents. That's not because MagpieRSS couldn't read
1136 the data, but rather because the new Magpie version puts that data in a
1137 location where the old version doesn't, and I was only looking in that
1138 newer location. Now it checks for both, meaning that posts will continue
1139 to display their contents even if you don't upgrade MagpieRSS. (But you
1140 **really should** upgrade it, anyway.)
1141
1142 * BUGFIX: RELATIVE URI RESOLUTION FOR POST CONTENT RESTORED. Some time
1143 back, I added support for resolving relative URIs against xml:base on
1144 feeds that support it to the MagpieRSS upgrade in FeedWordPress. Then I
1145 took out code that did the same thing from the main FeedWordPress code.
1146 Of course, the problem is that some people, even though it is clearly
1147 stupid or evil to do so, still include relative URIs for images or links
1148 in posts on feed formats that do *not* adequately support xml:base
1149 (notably, RSS 2.0 feeds). In response to a user request, I have added
1150 this functionality back in, so that MagpieRSS will resolve any relative
1151 URIs that it knows how to resolve using xml:base, and then FeedWordPress
1152 will attempt to resolve any relative URIs that are left over afterwards.
1153
1154 * BUGFIX: INTERFACE OPTION FOR SETTING SYNDICATED POST PUBLICATION STATUS
1155 ON A FEED-BY-FEED BASIS HAS BEEN RESTORED: Due to a version-checking
1156 bug, users of WordPress 2.7.x lost an option from the "Edit a syndicated
1157 feed" interface which allowed them to determine whether newly syndicated
1158 posts should be published immediately, held as "Pending Review," saved
1159 as drafts, or saved as private posts. (The option to change this
1160 setting globally remained in place, but users could no longer set it on
1161 a feed-by-feed basis.) The version-checking bug has been fixed, and the
1162 option has been restored.
1163
1164 * BUGFIX: "ARE YOU SURE?" FATAL ERROR ELIMINATED AND SECURITY IMPROVED:
1165 Under certain circumstances (for example, when users have configured
1166 their browser or proxy not to send HTTP Referer headers, for privacy or
1167 other reasons), many features in the FeedWordPress administrative
1168 interface (such as adding new feeds or changing settings) would hit a
1169 fatal error, displaying only a cryptic message reading "Are you sure?"
1170 and a blank page following it. This problem has been eliminated by
1171 taking advantage of WordPress's nonce functions, which allow the
1172 security check which ran into this error to work properly even without
1173 receiving an HTTP Referer header. (N.B.: WordPress's nonce functions
1174 were first introduced in WordPress 2.0.3. If you're using FeedWordPress
1175 with an older version of WordPress, there's no fix for this problem:
1176 you'll just need to turn Referer headers back on. Sorry.)
1177
1178 * BUGFIX: MANUALLY-ALTERED POST STATUS, COMMENT STATUS, AND PING STATUS NO
1179 LONGER REVERTED BY POST UPDATES: If you manually altered the post status,
1180 comment status, or ping status of a syndicated post from what it was set
1181 to when first syndicated -- for example, if you had a feed that was set
1182 to bring in new posts as "Pending Review," and you then marked some of
1183 the pending posts as "Published" and others as "Unpublished" -- then
1184 in previous versions of FeedWordPress, these manual changes to the
1185 status would be lost -- so that, for example, your Published or Unpublished
1186 articles would revert to Pending Review -- if the source feed made any
1187 upates to the item. This could make the Pending Review feature both
1188 unreliable and also extremely frustrating to work with. The good news is
1189 that this bug has since been fixed: if you manually update the status
1190 of a post, it will no longer be reverted if or when the post is updated.
1191
1192 * BUGFIX: OCCASIONAL FATAL ERROR ON UPDATE ELIMINATED: Under certain
1193 limited conditions (specifically, when both the title and the content of
1194 a post to be updated are empty), an attempt to update the post would
1195 result in a fatal error. This has been fixed.
1196
1197 * INTERFACE: "CONFIGURE SETTINGS" CONVENIENCE LINK ADDED TO CONFIRMATION
1198 MESSAGE WHEN A NEW FEED IS ADDED: When you add a new subscription to
1199 FeedWordPress, the message box that appears to confirm it now includes a
1200 handy link to the feed's settings subpage, so that you can quickly set
1201 up any special settings you may want to set up for the new feed, without
1202 having to hunt through the list of all your other subscriptions to pick
1203 out the new one.
1204
1205 * INTERFACE: SIMPLIFYING AND CLARIFYING AUTOMATIC UPDATES SETTINGS. I have
1206 removed an interval setting for the cronless automatic updates which has
1207 confused many FeedWordPress users. In past versions of FWP, when you
1208 turned on automatic updates, you would be presented with a time interval
1209 setting which controlled how often FeedWordPress would check for feeds
1210 ready to be polled for updates. (That is, it DID NOT control how often
1211 feeds *would be polled*; it controlled how often FeedWordPress would
1212 *check* for feeds that *had become ready to poll*. The schedule on which
1213 feeds became ready for polling was still controlled either by requests
1214 encoded in elements within the feed itself, or else according to an
1215 internal calculation within FeedWordPress, averaging out to about 1 hour,
1216 if the feed did not include any scheduling request elements.) Since many
1217 users very often (and understandably) confused the purpose of this
1218 setting, and since the setting is for a feature that's actually very
1219 unlikely to require any manual control by the user, I have removed the
1220 setting; FeedWordPress now simply uses the default value of checking for
1221 feeds to poll every 10 minutes.
1222
1223 * FEEDFINDER PERFORMANCE IMPROVEMENT: FeedWordPress's FeedFinder class
1224 now uses `array_unique()` to make sure that it doesn't waste time
1225 repeatedly iterating over and polling the same URI. Props to Camilo
1226 (<http://projects.radgeek.com/2008/12/14/feedwordpress-20081214/#comment-20090122160414>).
1227
1228 = 2008.1214 =
1229
1230 * WORDPRESS 2.7 COMPATIBILITY: FeedWordPress has been tested for
1231 compatibility with the newly released WordPress 2.7. WordPress 2.7 has
1232 deprecated the Snoopy library for HTTP requests, which caused a fatal
1233 error for users who had not installed the MagpieRSS upgrade (or whose
1234 installation of the MagpieRSS upgrade was overwritten by a recent update
1235 of WordPress). FeedWordPress now handles things gracefully when Snoopy
1236 is not immediately available.
1237
1238 * INTERFACE SPIFFED UP: Interface elements have been updated so that
1239 FeedWordPress's management interface fits in more naturally with the
1240 WordPress 2.7 interface (including a new logo and a number of small
1241 interface tweaks).
1242
1243 * BUG WITH TAGS FOR SYNDICATED ARTICLES FIXED: Several users encountered a
1244 bug with the option to add tags to all syndicated posts under
1245 Syndication --> Settings -- if you told FeedWordPress to add more than
1246 one tag to all syndicated posts, instead of doing so correctly, it would
1247 add a *single* tag instead, whose name was composed of the names of all
1248 the tags you asked it to add. This bug was the result of nothing more
1249 dignified than a typographical error on my part. It has now been fixed.
1250
1251 * MORE INFORMATION AVAILABLE WHEN FEEDWORDPRESS CAN'T FIND A FEED: When
1252 you enter a URL for a new syndication source, FeedWordPress uses a
1253 simple feed-finding algorithm (originally based on Mark Pilgrim's
1254 Universal Feed Finder) to try to determine whether the URL is the URL
1255 for a feed, or, if the URL points to an ordinary website rather than to
1256 a feed, whether there is a feed for that website. All well and good, but
1257 if FeedWordPress failed to find a feed, for whatever reason, it would
1258 typically return nothing more than a nasty little note to the effect of
1259 "no feed found," without any explanation of what went wrong.
1260 FeedWordPress now keeps track of error conditions from the HTTP
1261 requests that it uses in the course of looking for the feed, and so may
1262 be able to give you a bit more information about the nature of the
1263 problem if something goes wrong.
1264
1265
1266 = 2008.1105 =
1267
1268 * INTERFACE RESTRUCTURING AND SYNDICATION --> AUTHORS PAGE: As a first
1269 step towards modularizing and better organizing the user interface, a
1270 new "Authors" subpage has been created under the Syndication menu, which
1271 controls settings for syndicated authors, both at the global default
1272 level and at level of individual syndicated feeds.
1273
1274 * BUG RELATED TO THE ATTRIBUTION OF POSTS TO THE WRONG AUTHOR FIXED: Some
1275 users encountered an issue in which posts by different authors on
1276 different blogs -- especially blogs generated by Blogger -- were
1277 mistakenly attributed to a single author. The problem was caused by the
1278 way in which FeedWordPress matches syndicated authors to user accounts
1279 in the WordPress database: normally, if two feeds each list an author
1280 with the same e-mail address, they are counted as being the same person.
1281 Normally this works well, but it creates an issue in cases where
1282 blogging software assigns a single anonymous e-mail address to users who
1283 do not want their real e-mail address published. This is, for example,
1284 what Blogger does (by giving all users a default e-mail address of
1285 <noreply@blogger.com> if they don't want their own e-mail address
1286 listed). FeedWordPress now allows the user to correct for this problem
1287 with a couple of new settings under **Syndication --> Authors**, which
1288 allow users to turn off e-mail based author matching for particular
1289 addresses, or, if desired, to turn it off entirely. By default, e-mail
1290 based author matching is still turned on, but disabled for a list of
1291 known generic e-mail addresses. Right now, the "list" consists entirely
1292 of <noreply@blogger.com>; if you know other addresses that should be
1293 added, please [contact me](http://radgeek.com/contact) to let me know.
1294
1295 Please note that if you have already encountered this issue on your
1296 blog, upgrading FeedWordPress will prevent it from re-occurring in the
1297 future, but you still need to do two other things to fix the existing
1298 problem on your blog.
1299
1300 First, for each feed where posts have been mis-attributed, you need to
1301 change the existing author mapping rules to re-map a a syndicated
1302 author's name to the proper target account. Go to **Syndication -->
1303 Authors**, select the feed you want to change from the drop-down list,
1304 and then change the settings under the "Syndicated Authors" section.
1305 (You will probably need to select "will be assigned to a new user..." to
1306 create a new user account with the appropriate name.)
1307
1308 Second, for each feed where posts have been mis-attributed, you need to
1309 re-assign already-syndicated posts that were mis-attributed to the
1310 correct author. You can do that from **Syndication --> Authors** by
1311 using the author re-assignment feature, described below.
1312
1313 * AUTHOR RE-ASSIGNMENT FOR A PARTICULAR FEED: The author settings page
1314 for each syndicated feed, under **Syndication --> Authors**, now
1315 includes an section titled "Fixing mis-matched authors," which provides
1316 an interface for re-assigning or deleting all posts attributed to a
1317 particular author on a particular feed.
1318
1319 * SUPPORT FOR `<atom:source>` ELEMENT IN SYNDICATED FEEDS: Some feeds
1320 (for example, those produced by FeedWordPress) aggregate content from
1321 several different sources, and include information about the original
1322 source of the post in an `<atom:source>` element. A new setting under
1323 **Syndication --> Options** allows you to control what FeedWordPress
1324 will report as the source of posts syndicated from aggregator feeds in
1325 your templates and feeds: you can have FeedWordPress report that the
1326 source of a post is the aggregator feed itself, or you can have it
1327 report that the source of a post is the original source that the
1328 aggregator originally syndicated the post from.
1329
1330 By default, FeedWordPress will report the aggregator, not the original
1331 source, as the source of a syndicated item.
1332
1333 * LOAD BALANCING AND TIME LIMITING FEATURES FOR UPDATES: Some users have
1334 encountered issues due to running up against PHP execution time limits
1335 during the process of updating large syndicated feeds, or a very large
1336 set of syndicated feeds. FeedWordPress now has a feature that allows you
1337 to limit the total amount of time spent updating a feed, through the
1338 "Time limit on updates" setting under **Syndication --> Options**. By
1339 turning on this setting and adjusting the time limit to a low enough
1340 figure to avoid your PHP installation's time-out setting. (PHP execution
1341 time limits are usually in the vicinity of 30 seconds, so an update
1342 time limit of 25 seconds or so should provide plenty of time for updates
1343 while allowing a cushion of time for other, non-update-related functions
1344 to do their work.)
1345
1346 If feed updates are interrupted by the time limit, FeedWordPress uses
1347 some simple load balancing features to make sure that updates to other
1348 feeds will not be blocked by the time-hogging feed, and will also make
1349 sure that when the interrupted update is resumed, FeedWordPress will
1350 skip ahead to resume processing items at the point at which it was
1351 interrupted last time, so that posts further down in the feed will
1352 eventually get processed, and not get blocked by the amount of time it
1353 takes to process the items higher up in the feed.
1354
1355 * `guid` INDEX CREATION BUTTON: FeedWordPress frequently issues queries on
1356 the `guid` column of the WordPress posts database (since it uses post
1357 guid URIs to keep track of which posts it has syndicated). In very large
1358 FeedWordPress installations, you can often significantly improve
1359 performance by creating a database index on the `guid` column, but
1360 normally you would need to poke around with MySQL or a tool like
1361 phpMyAdmin to do this. FeedWordPress can now save you the trouble: to
1362 create an index on the `guid` column, just go to
1363 **Syndication --> Options**, and mash the button at the bottom of the
1364 "Back End" section.
1365
1366 = 2008.1101 =
1367
1368 * INTERFACE BUG THAT PREVENTED ADDING NEW SITES FIXED: The UI reforms in
1369 FWP 2008.1030 unintentionally introduced a bug that prevents clean
1370 installations of FeedWordPress from providing an input box for adding
1371 new feeds to the list of syndicated feeds. This bug has been fixed.
1372
1373 = 2008.1030 =
1374
1375 * WORDPRESS 2.6 COMPATIBILITY: FeedWordPress should now be compatible with
1376 WordPress 2.6, and should work more or less seamlessly with the new post
1377 revision system. A bug which caused multiple new revisions to be created
1378 for posts on certain feeds, regardless of whether or not the item had
1379 been updated, has been fixed.
1380
1381 * INTERFACE IMPROVEMENTS: The user interface has been substantially
1382 restyled to fit in better with the visual style of WordPress 2.5 and
1383 2.6.
1384
1385 * YOUTUBE BUG FIXED: POSTS SYNDICATED THROUGH AN AUTOMATIC UPDATE ARE NO
1386 LONGER STRIPPED OF `<OBJECT>` TAGS AND CERTAIN OTHER HTML ELEMENTS: Due
1387 to the way that some versions of WordPress process posts that are
1388 inserted into the database when no user is logged in, many users
1389 experienced an issue where YouTube videos and other content using the
1390 HTML `<object>` tag would be stripped out of posts that were syndicated
1391 during an automatic update. (Posts that were syndicated through manual
1392 updates from within the WordPress Dashboard were not affected, because
1393 the issue does not arise when an update is executed under a logged-in
1394 administrator's credentials.) This bug has now been fixed; YouTube
1395 videos and other content using `<object>` tags should now appear
1396 properly in syndicated posts, regardless of the way in which the post
1397 was syndicated.
1398
1399 * AJAX BUGS FIXED: Bugs which blocked the normal operation of WordPress
1400 2.5's AJAX interface elements when FeedWordPress was activated have been
1401 fixed.
1402
1403 * TAG SUPPORT: A couple of features have been introduced to take advantage
1404 of the tagging features in WordPress 2.3.x, 2.5.x, and 2.6.x. Now, when
1405 unfamiliar categories are encountered for posts on a feed, you can
1406 choose for FeedWordPress (1) to drop the category; (2) to drop the
1407 category and to filter out any post that does not match at least one
1408 familiar category; (3) to create a new category with that name, or,
1409 now, you can also have FeedWordPress (4) create a new *tag* with that
1410 name. This option can be set site-wide under Syndication --> Options,
1411 or it can be set on a feed-by-feed basis in a feed's Edit screen.
1412
1413 In addition, you can now set particular tags to apply to all incoming
1414 syndicated posts, under Syndication --> Options, or you can set tags
1415 to apply to all incoming syndicated posts from a particular feed in that
1416 feed's Edit screen.
1417
1418 * FORMATTING FILTERS: There is a new option available under Syndication ->
1419 Options which allows users to choose whether or not to expose syndicated
1420 posts to being altered by formatting filters. By default, FeedWordPress
1421 has always protected syndicated posts (which are already in display-ready
1422 HTML when they are syndicated) from being reformatted by formatting
1423 filters. However, this approach means that certain plugins which depend
1424 on formatting filters (for example, to add "Share This" bars or relevant
1425 links to the end of a post) are blocked from working on any syndicated
1426 posts. If you want to use one of these plugins together with
1427 FeedWordPress, you can now do so by changing the "Formatting Filters"
1428 setting from "Protect" to "Expose."
1429
1430 * `<atom:source>` ELEMENTS NOW INCLUDED IN ATOM FEED: Atom 1.0 provides
1431 a standard method for aggregators to indicate information about the original source of
1432 a syndicated post, using the `<atom:source>` element. FeedWordPress now
1433 introduces standard `<atom:source>` elements including the title, homepage, and
1434 feed URI of the source from which a syndicated post was syndicated. Cf.
1435 <http://www.atomenabled.org/developers/syndication/atom-format-spec.php#element.source>
1436
1437 * MODULARIZATION OF CODE: The code for different elements of FeedWordPress
1438 has been broken out into several modules for easier inspection,
1439 documentation, and maintenance of the code.
1440
1441 * VERSIONING SCHEME CHANGED: FeedWordPress's feature set has proven stable
1442 enough that it can now be removed from beta status; a good thing, since
1443 I was very quickly running out of version numbers to use. New releases
1444 of FeedWordPress will have version numbers based on the date of their
1445 release.
1446
1447 = 0.993 =
1448
1449 * WORDPRESS 2.5.1 COMPATIBILITY: FeedWordPress should now be compatible
1450 with WordPress 2.5.1.
1451
1452 * WORDPRESS 2.5 INTERFACE IMPROVEMENTS: FeedWordPress's Dashboard
1453 interface has undergone several cosmetic changes that should help it
1454 integrate better with the WordPress Dashboard interface in WordPress
1455 version 2.5.x.
1456
1457 * SYNDICATED POSTS CAN BE MARKED AS "PENDING REVIEW": WordPress 2.3 users
1458 can now take advantage of WordPress's new "Pending Review" features for
1459 incoming syndicated posts. Posts marked as "Pending Review" are not
1460 published immediately, but are marked as ready to be reviewed by an
1461 Administrator or Editor, who can then choose to publish the post or
1462 hold it back. If you want to review syndicated posts from a particular
1463 feed, or from all feeds, before they are posted, then use
1464 Syndication --> Syndicated Sites --> Edit or Syndication --> Options to
1465 change the settings for handling new posts.
1466
1467 * AWARE OF NEW URI FOR del.icio.us FEEDS: Previous releases of
1468 FeedWordPress already automatically split del.icio.us tags up
1469 appropriately appropriately when generating categories. (del.icio.us
1470 feeds smoosh all the tags into a single `<dc:subject>` element,
1471 separated by spaces; FeedWordPress un-smooshes them into multiple
1472 categories by separating them at whitespace.) Unfortunately, del.icio.us
1473 recently broke the existing behavior by changing host names for their
1474 feeds from del.icio.us to feeds.delicious.com. Version 0.993 accounts
1475 for the new host name and un-breaks the tag splitting.
1476
1477 = 0.992 =
1478
1479 * AUTHOR RE-MAPPING: FeedWordPress now offers considerable control over
1480 how author names on a feed are translated into usernames within the
1481 WordPress database. When a post by an unrecognized author comes in,
1482 Administrators can now specify any username as the default username to
1483 assign the post to by setting the option in Syndication --> Options
1484 (formerly FeedWordPress only allowed you to assign such posts to user
1485 #1, the site administrator). Administrators can also create re-mapping
1486 rules for particular feeds (under Syndication --> Syndicated Sites -->
1487 Edit), so that (for example) any posts attributed to "Administrator"
1488 on the feed <http://praxeology.net/blog/feed/> will be assigned to
1489 a user named "Roderick T. Long," rather than a user named
1490 "Administrator." These settings also allow administrators to filter out
1491 posts by particular users, and to control what will happen when
1492 FeedWordPress encounters a post by an unrecognized user on that
1493 particular feed.
1494
1495 * BUG RELATED TO URIS CONTAINING AMPERSAND CHARACTERS FIXED: A bug in
1496 WordPress 2.x's handling of URIs in Blogroll links created problems for
1497 updating any feeds whose URIs included an ampersand character, such as
1498 Google News RSS feeds and other feeds that have multiple parameters
1499 passed through HTTP GET. If you experienced this bug, the most likely
1500 effect was that FeedWordPress simply would not import new posts from a
1501 feed when instructred to do so, returning a "0 new posts" response. In
1502 other cases, it might lead to unpredictable results from feed updates,
1503 such as importing posts which were not contained in the feed being
1504 syndicated, but which did appear elsewhere on the same website. This bug
1505 has, hopefully, been resolved, by correcting for the bug in WordPress.
1506
1507 = 0.991 =
1508
1509 * WORDPRESS MU COMPATIBILITY: FeedWordPress should now be compatible with
1510 recent releases of WordPress MU. Once FeedWordPress is made available
1511 as a plugin, each individual blog can choose to activate FeedWordPress
1512 and syndicate content from its own set of contributors.
1513
1514 * DISPLAY OF MAGPIE WARNINGS: A number of MagpieRSS warnings or error
1515 messages that were displayed when performing an automatic update are
1516 no longer displayed, unless debugging parameters have been explicitly
1517 enabled.
1518
1519 * BUG RELATED TO INTERNATIONAL CHARACTERS IN AUTHOR NAMES FIXED: Due to a
1520 subtle incompatability between the way that FeedWordPress generated new
1521 user information, and the way that WordPress 2.0 and later added new
1522 authors to the database, FeedWordPress might end up creating duplicate
1523 authors, or throwing a critical error message, when it encountered
1524 authors whose names included international characters. This
1525 incompatability has now been fixed; hopefully, authors with
1526 international characters in their names should now be handled properly.
1527
1528 * `<media:content>` BUG IN MAGPIERSS FIXED: A bug in MagpieRSS's handling
1529 of namespaced elements has been fixed. Among other things, this bug
1530 caused items containing a Yahoo MediaRSS `<media:content>` element (such
1531 as many of the feeds produced by wordpress.com) to be represented
1532 incorrectly, with only a capital "A" where the content of the post
1533 should have been. Feeds containing `<media:content>` elements should now
1534 be syndicated correctly.
1535
1536 * update_feedwordpress PARAMETER: You can now use an HTTP GET parameter
1537 (`update_feedwordpress=1`) to request that FeedWordPress poll its feeds
1538 for updates. When used together with a crontab or other means of
1539 scheduling tasks, this means that you can keep your blog automatically
1540 updated on a regular schedule, even if you do not choose to use the
1541 cron-less automatic updates option.
1542
1543 * Some minor interface-related bugs were also fixed.
1544
1545
1546 = 0.99 =
1547
1548 Version 0.99 adds several significant new features, fixes some bugs, and
1549 provides compatability with WordPress 2.2.x and 2.3.x.
1550
1551 * WORDPRESS 2.2 AND 2.3 COMPATIBILITY: FeedWordPress should now be
1552 compatible with WordPress version 2.2 and the upcoming WordPress
1553 version 2.3. In particular, it has been tested extensively against
1554 WordPress 2.2.3 and WordPress 2.3 Release Candidate 1.
1555
1556 * AUTOMATIC UPDATES WITHOUT CRON: FeedWordPress now allows you to
1557 automatically schedule checks for new posts without using external task
1558 scheduling tools such as cron. In order to enable automatic updates, go
1559 to **Syndication --> Options** and set "Check for new posts" to
1560 "automatically." For details, see "Automatic Feed Updates" in
1561 README.text.
1562
1563 An important side-effect of the changes to the update system is that if
1564 you were previously using the cron job and the `update-feeds.php` script
1565 to schedule updates, you need to change your cron set-up. The old
1566 `update-feeds.php` script no longer exists. Instead, if you wish to use
1567 a cron job to guarantee updates on a particular schedule, you should
1568 have the cron job fetch the front page of your blog (for example, by
1569 using `curl http://www.zyx.com/blog/ > /dev/null`) instead of activating
1570 the `update-feeds.php` script. If automatic updates have been enabled,
1571 fetching the front page will automatically trigger the update process.
1572
1573 * INTERFACE REORGANIZATION: All FeedWordPress functions are now located
1574 under a top-level "Syndication" menu in the WordPress Dashboard. To
1575 manage the list of syndicated sites, manually check for new posts on
1576 one or more feeds, or syndicate a new site, you should use the main page
1577 under **Syndication**. To change global settings for FeedWordPress,
1578 you should use **Syndication --> Options**.
1579
1580 * FILE STRUCTURE REORGANIZATION: Due to a combination of changing styles
1581 for FeedWordPress plugins and lingering bugs in the FeedWordPress admin
1582 menu code, the code for FeedWordPress is now contained in two different
1583 PHP files, which should be installed together in a subdirectory of your
1584 plugins directory named `feedwordpress`. (See README.text for
1585 installation and upgrade instructions relating to the change.)
1586
1587 * MULTIPLE CATEGORIES SETTING: Some feeds use non-standard methods to
1588 indicate multiple categories within a single category element. (The most
1589 popular site to do this is del.icio.us, which separates tags with a
1590 space.) FeedWordPress now allows you to set an optional setting, for any
1591 feed which does this, indicating the character or characters used to
1592 divide multiple categories, using a Perl-compatible regular expression.
1593 (In the case of del.icio.us feeds, FeedWordPress will automatically use
1594 \s for the pattern without your having to do any further configuration.)
1595 To turn this setting on, simply use the "Edit" link for the feed that
1596 you want to turn it on for.
1597
1598 * REGULAR EXPRESSION BUG FIXED: Eliminated a minor bug in the regular
1599 expressions for e-mail addresses (used in parsing RSS `author`
1600 elements), which could produce unsightly error messages for some users
1601 parsing RSS 2.0 feeds.
1602
1603 * DATE / UPDATE BUG FIXED: A bug in date handling was eliminated that may
1604 have caused problems if any of (1) WordPress, or (2) PHP, or (3) your
1605 web server, or (4) your MySQL server, has been set to use a different
1606 time zone from the one that any of the others is set to use. If
1607 FeedWordPress has not been properly updating updated posts, or has been
1608 updating posts when there shouldn't be any changes for the update, this
1609 release may solve that problem.
1610
1611 * GOOGLE READER BUGS FIXED: A couple of bugs that made it difficult for
1612 FeedWordPress to interact with Google Reader public feeds have been
1613 fixed. Firstly, if you encountered an error message reading "There was a
1614 problem adding the newsfeed. [SQL: ]" when you tried to add the feed,
1615 the cause of this error has been fixed. Secondly, if you succeeded in
1616 getting FeedWordPress to check a Google Reader feed, only to find that
1617 the title of posts had junk squashed on to the end of them, that bug
1618 has been fixed too. To fix this bug, you must install the newest version
1619 of the optional MagpieRSS upgrade.
1620
1621 * FILTER PARAMETERS: Due to an old, old bug in WordPress 1.5.0 (which was
1622 what was available back when I first wrote the filter interface),
1623 FeedWordPress has traditionally only passed one parameter to
1624 syndicated_item and syndicated_post filters functions -- an array
1625 containing either the Magpie representation of a syndicated item from
1626 the feed, or the database representation of a post about to be inserted
1627 into the WordPress database. If you needed information about the feed
1628 that the item came from, this was accessible only through a pair of
1629 global variables, $fwp_channel and $fwp_feedmeta.
1630
1631 Since it's been a pretty long time since WordPress 1.5.0 was in
1632 widespread usage, I have gone ahead and added an optional second
1633 parameter to the invocation of the syndicated_item and syndicated_post
1634 filters. If you have written a filter for FeedWordPress that uses either
1635 of these hooks, you can now register that filter to accept 2 parameters.
1636 If you do so, the second parameter will be a SyndicatedPost object,
1637 which, among other things, allows you to access information about the
1638 feed from which an item is syndicated using the $post->feed and the
1639 $post->feedmeta elements (where $post is the name of the second
1640 parameter).
1641
1642 NOTE THAT THE OLD GLOBAL VARIABLES ARE STILL AVAILABLE, for the time
1643 being at least, so existing filters will not break with the upgrade.
1644 They should be considered deprecated, however, and may be eliminated in
1645 the future.
1646
1647 * FILTER CHANGE / BUGFIX: the array that is passed as the first argument
1648 syndicated_post filters no longer is no longer backslash-escaped for
1649 MySQL when filters are called. This was originally a bug, or an
1650 oversight; the contents of the array should only be escaped for the
1651 database *after* they have gone through all filters. IF YOU HAVE WRITTEN
1652 ANY syndicated_post FILTERS THAT PRESUME THE OLD BEHAVIOR OF PASSING IN
1653 STRINGS THAT ARE ALREADY BACKSLASH-ESCAPED, UPDATE YOUR FILTERS
1654 ACCORDINGLY.
1655
1656 * OTHER MINOR BUGFIXES AND INTERNAL CHANGES: The internal architecture of
1657 FeedWordPress has been significantly changed to make the code more
1658 modular and clean; hopefully this should help reduce the number of
1659 compatibility updates that are needed, and make them easier and quicker
1660 when they are needed.
1661
1662 = 0.981 =
1663
1664 Version 0.981 is a narrowly targeted bugfix and compatibility release, whose
1665 main purpose is to resolve a major outstanding problem: the incompatibility
1666 between version 0.98 of WordPress and the recently released WordPress 2.1.
1667
1668 * WORDPRESS 2.1 COMPATIBILITY: FeedWordPress is now compatible with
1669 WordPress 2.1, as well as retaining its existing support for WordPress
1670 2.0 and 1.5. Incompatibilities that resulted in database warnings, fatal
1671 errors, and which prevented FeedWordPress from syndicating new posts,
1672 have been eliminated.
1673
1674 * RSS-FUNCTIONS.PHP RENAMED TO RSS.PHP: if you use the upgraded MagpieRSS
1675 replacement that's included with FeedWordPress, be sure to note that
1676 there are now *two* files to upload from the `OPTIONAL/wp-includes`
1677 subdirectory in order to carry out the upgrade: rss-functions.php and
1678 rss.php. **It is necessary to upload both files**, due to a change in
1679 the file naming scheme in WordPress 2.1, and it is necessary to do so
1680 whether you are using WordPress 2.1 or not. If you only upload the
1681 `rss-functions.php` file as in previous installations you will not have
1682 a working copy of MagpieRSS; the rss.php file contains the actual code.
1683
1684 * DATE BUG AFFECTING SOME PHP INSTALLATIONS RESOLVED: due to a subtle bug
1685 in parse_w3cdtf(), some installations of PHP encountered problems with
1686 FeedWordPress's attempt to date posts, which would cause some new posts
1687 on Atom feeds to be dated as if they had apppeared in 1969 or 1970
1688 (thus, effectively, never appearing on front page at all). This bug in
1689 the date handling should now be fixed.
1690
1691 * PHP <?=...?> SHORT FORM ELIMINATED: some installations of PHP do not
1692 allow the <?=...?> short form for printing PHP values, which was used
1693 extensively in the FeedWordPress interface code. Since this could cause
1694 fatal errors for users with the wrong installation of PHP, the short
1695 form has been replaced with full PHP echo statements, and is no longer
1696 used in FeedWordPress.
1697
1698 * BETTER USER INTERFACE INTEGRATION WITH WORDPRESS 2.x: Some minor changes
1699 have been made to help the FeedWordPress interface pages blend in better
1700 with the user interface when running under WordPress 2.x.
1701
1702 * GLOBAL CATEGORIES BUG RESOLVED: a bug that prevented some users from
1703 setting one or more categories to apply to syndicated posts from all
1704 feeds (using the checkbox interface under Options --> Syndication) has
1705 been resolved.
1706
1707 = 0.98 =
1708
1709 * WORDPRESS 2.0 COMPATIBILITY: This is a narrowly-targeted release to
1710 solve a major outstanding problem. FeedWordPress is now compatible with
1711 both WordPress 1.5 and WordPress 2.0. Incompatibilities that caused
1712 fatal SQL errors, and a more subtle bug with off-kilter counts of posts
1713 under a given category, have been resolved. FeedWordPress tests for
1714 database schema using the global $wp_db_version variable (if null, then
1715 we presume that we're dealing with WordPress 1.5).
1716
1717 NOTE: I have **not** fully tested FeedWordPress with WordPress 2.0.
1718 Further testing may reveal more bugs. However, you should now be able
1719 to get at least basic FeedWordPress functionality up and running.
1720
1721 * AUTHOR MATCHING: FeedWordPress tests several fields to see if it can
1722 identify the author of the post as a user already in the WordPress user
1723 database. In previous versions, it tested the user login, the nickname,
1724 and tested for "aliases" listed in the Profile (see documentation). FWP
1725 now also matches authors on the basis of e-mail address (*if* an e-mail
1726 address is present). This is particularly helpful for formats such as
1727 RSS 2.0, in which authors are primarily identified by e-mail addresses.
1728
1729 = 0.97 =
1730
1731 * INSTALLATION PROCEDURE: Some of the changes between 0.96 and 0.97
1732 require upgrades to the meta-data stored by FeedWordPress to work
1733 properly. Thus, if you are upgrading from 0.96 or earlier to 0.97, most
1734 FeedWordPress operations (including updates and template functions)
1735 WILL BE DISABLED until you run the upgrade procedure. Fortunately,
1736 running the upgrade procedure is easy: just go to either Options -->
1737 Syndication or Links --> Syndicated in the WordPress Dashboard and press
1738 the button.
1739
1740 * FEED FORMAT SUPPORT: Support has been added for the Atom 1.0 IETF
1741 standard. Several other elements are also newly supported
1742 (dcterms:created, dcterms:issued, dcterms:modified, dc:identifier,
1743 proper support for the RSS 2.0 guid element, the RSS 2.0 author element,
1744 the use of Atom author or Dublin Core dc:creator constructs at the feed
1745 level to identify the author of individual items, etc.)
1746
1747 N.B.: full support of several Atom 1.0 features, such as categories
1748 and enclosures, requires you to install the optional rss-functions.php
1749 upgrade in your wp-includes directory.
1750
1751 * BUG FIX: Running `update-feeds.php` from command line or crontab
1752 returned "I don't syndicate..." errors. It turns out that WordPress
1753 sometimes tramples on the internal PHP superglobals that I depended on
1754 to determine whether or not the script was being invoked from the
1755 command line. This has been fixed (the variables are now checked
1756 *before* WordPress can trample them). Note that `update-feeds.php` has
1757 been thoroughly overhauled anyway; see below for details.
1758
1759 * BUG FIX: Duplicate categories or author names. Fixed two bugs that could
1760 create duplicate author and/or category names when the name contained
1761 either (a) certain international characters (causing a mismatch between
1762 MySQL and PHP's handling of lowercasing text), or (b) characters that
1763 have a special meaning in regular expressions (causing MySQL errors when
1764 looking for the author or category due to regexp syntax errors). These
1765 should now be fixed thanks to careful escaping of names that go into
1766 regular expressions and careful matching of lowercasing functions
1767 (comparing results from PHP only to other results from PHP, and results
1768 from MySQL only to other results from MySQL).
1769
1770 * BUG FIX: Items dated December 31, 1969 should appear less often. The
1771 function for parsing W3C date-time format dates that ships with
1772 MagpieRSS can only correctly parse fully-specified dates with a
1773 fully-specified time, but valid W3C date-time format dates may omit the
1774 time, the day of the month, or even the month. Some feeds in the wild
1775 date their items with coarse-grained dates, so the optional
1776 `rss-functions.php` upgrade now includes a more flexible parse_w3cdtf()
1777 function that will work with both coarse-grained and fully-specified
1778 dates. (If parts of the date or the time are omitted, they are filled in
1779 with values based on the current time, so '2005-09-10' will be dated to
1780 the current time on that day; '2004' will be dated to this day and time
1781 one year ago.
1782
1783 N.B.: This fix is only available in the optional `rss-functions.php`
1784 upgrade.
1785
1786 * BUG FIX: Evil use of HTTP GET has been undone. The WordPress interface
1787 is riddled with inappropriate (non-idempotent) uses of HTTP GET queries
1788 (ordinary links that make the server do something with significant
1789 side-effects, such as deleting a post or a link from the database).
1790 FeedWordPress did some of this too, especially in places where it aped
1791 the WordPress interface (e.g. the "Delete" links in Links -->
1792 Syndicated). That's bad business, though. I've changed the interface so
1793 that all the examples of improper side-effects that I can find now
1794 require an HTTP POST to take effect. I think I got pretty much
1795 everything; if there's anything that I missed, let me know.
1796

1798
1799 * BUG FIX: Categories applied by `cats` setting should no longer prevent
1800 category-based filtering from working. In FeedWordPress, you can (1)
1801 apply certain categories to all syndicated posts, or all posts from
1802 a particular feed; and (2) filter out all posts that don't match one
1803 of the categories that are already in the WordPress database (allowing
1804 for simple category-based filtering; just load up WordPress with the
1805 categories you want to accept, and then tell FeedWordPress not to create
1806 new ones). However, the way that (1) and (2) were implemented meant that
1807 you couldn't effectively use them together; once you applied a known
1808 category to all syndicated posts from a particular feed, it meant that
1809 they'd have at least one familiar category (the category or categories
1810 you were applying), and that would get all posts past the filter no
1811 matter what categories they were originally from.
1812
1813 Well, no longer. You can still apply categories to all syndicated posts
1814 (using either Syndication --> Options, or the feed-level settings under
1815 Links --> Syndicated). But these categories are not applied to the post
1816 until *after* it has already passed by the "familiar categories" filter.
1817 So now, if you want, you can do category filtering and *then* apply as
1818 many categories as you please to all and only posts that pass the filter.
1819
1820 * BUG FIX: Other minor typos and HTML gaffes were fixed along the way.
1821
1822 * PERFORMANCE: get_feed_meta() no longer hits the database for information
1823 on every call; it now caches link data in memory, so FeedWordPress only
1824 goes to the database once for each syndicated link. This may
1825 substantially improve performance if your database server resources
1826 are tight and your templates make a lot of use of custom settings from
1827 get_feed_meta().
1828
1829 * API CHANGE: Link ID numbers, rather than RSS URIs, are now used to
1830 identify the feed from which a post is syndicated when you use template
1831 functions such as get_feed_meta(). The practical upshot of this is you
1832 can switch feeds, or change the feed address for a particular syndicated
1833 site, without breaking your templates for all the posts that were
1834 syndicated from the earlier URI.
1835
1836 * API CHANGE: if you have plugins or templates that make use of the
1837 get_feed_meta() function or the $fwp_feedmeta global, note that the
1838 data formerly located under the `uri` and `name` fields is now located
1839 under the `link/uri` field and the `link/name` field, respectively. Note
1840 also that you can access the link ID number for any given feed under the
1841 global $fwp_feedmeta['link/id'] (in plugins) or
1842 get_feed_meta('link/id') (in a template in post contexts).
1843
1844 * FEATURE: the settings for individual feeds can now be edited using a
1845 humane interface (where formerly you had to tweak key-value pairs in the
1846 Link Notes section). To edit settings for a feed, pick the feed that you
1847 want under Links --> Syndicated and click the Edit link.
1848
1849 * FEATURE: The "Unsubscribe" button (formerly "Delete") in Links -->
1850 Syndicated now offers three options for unsubscribing from a feed: (1)
1851 turning off the subscription without deleting the feed data or affecting
1852 posts that were syndicated from the feed (this works by setting the Link
1853 for the feed as "invisible"); (2) deleting the feed data and all of the
1854 posts that were syndicated from the feed; or (3) deleting the feed data
1855 and *keeping* the posts that were syndicated from the feed
1856 setting the Link to "Invisible" (meaning that it will not be displayed
1857 in lists of the site links on the front page, and it won't be checked
1858 for updates; (2) deleting the Link and all of the posts that were
1859 syndicated from its feed; or (3) deleting the feed data but keeping the
1860 posts that were syndicated (which will henceforward be treated as if
1861 they were local rather than syndicated posts). (Note that (1) is usually
1862 the best option for aggregator sites, unless you want to clean up the
1863 results of an error or a test.)
1864
1865 * FEATURE / BUG FIX: If you have been receiving mysterious "I don't
1866 syndicate...", or "(local) HTTP status code was not 200", or "(local)
1867 transport error - could not open socket", or "parse error - not well
1868 formed" errors, then this update may solve your problems, and if it does
1869 *not* solve them, it will at least make the reasons for the problems
1870 easier to understand. That's because I've overhauled the way that
1871 FeedWordPress goes about updating feeds.
1872
1873 If you use the command-line PHP scripting method to run scheduled
1874 updates, then not much should change for you, except for fewer
1875 mysterious errors. If you have done updates by sending periodic HTTP
1876 requests to <http://your-blog.com/path/wp-content/update-feeds.php>,
1877 then the details have changed somewhat; mostly in such a way as to make
1878 things easier on you. See the README file or online documentation on
1879 Staying Current for the details.
1880
1881 * FEATURE: FeedWordPress now features a more sophisticated system for
1882 timed updates. Instead of polling *every* subscribed feed for updates
1883 *each* time `update-feeds.php` is run, FeedWordPress now keeps track of
1884 the last time it polled each feed, and only polls them again after a
1885 certain period of time has passed. The amount of time is normally set
1886 randomly for each feed, in a period between 30 minutes and 2 hours (so
1887 as to stagger updates over time rather than polling all of the feeds at once. However, the length of time between updates can also be set
1888 directly by the feed, which brings us to ...
1889
1890 * FEATURE: FeedWordPress now respects the settings in the `ttl` and
1891 Syndication Module RSS elements. Feeds with these elements set will not
1892 be polled any more frequently than they indicate with these feeds unless
1893 the user manually forces FeedWordPress to poll the feed (see Links -->
1894 Syndicated --> Edit settings).
1895
1896 = 0.96 =
1897
1898 * FEATURE: support has been added for enclosures in RSS 2.0 and Atom
1899 0.6+ newsfeeds. WordPress already supports adding enclosures to an
1900 item; FeedWordPress merely gets the information on the enclosure
1901 from the feed it is syndicating and plugs that information directly
1902 into the WordPress database so that (among other things) that post
1903 will have its enclosure listed in your blog's RSS 2 newsfeed.
1904
1905 Note that enclosure support requires using the optional MagpieRSS
1906 upgrade (i.e., replacing your `wp-includes/rss-functions.php` with
1907 `OPTIONAL/wp-includes/rss-functions.php` from the FWP archive)
1908
1909 * FEATURE: for completeness's sake, there is now a feed setting,
1910 `hardcode url`, that allows you to set the URI for the front page
1911 of a contributor's website manually (that is, prevent it from being
1912 automatically updated from the feed channel link on each update). To
1913 set the URI manually, put a line like this in the Link Notes section
1914 of a feed:
1915
1916 hardcode url: yes
1917
1918 You can also instruct FeedWordPress to use hardcoded URIs by default
1919 on all feeds using Options --> Syndication
1920
1921 * FEATURE: by default, when FeedWordPress finds new syndicated posts,
1922 it (1) publishes them immediately, (2) turns comments off, and (3)
1923 turns trackback / pingback pings off. You can now alter all three
1924 default behaviors (e.g., to allow pings on syndicated posts, or to
1925 send newly-syndicated posts to the draft pile for moderation) using
1926 Options --> Syndication
1927
1928
1929 = From 0.91 to 0.95 =
1930
1931 * BUG FIX: Fixed an obscure bug in the handling of categories: categories with trailing whitespace could cause categories with duplicate names to be created. This no longer happens. While I was at it I tightened up the operation of FeedWordPress::lookup_categories() a bit in general.
1932
1933 * FEATURE DEPRECATED: the feed setting `hardcode categories` is now deprecated in favor of `unknown categories` (see below), which allows you to strip off any syndication categories not already in your database using `unknown categories: default` or `unknown categories: filter`. If you have `hardcode categories: yes` set on a feed, this will be treated as `unknown categories: default` (i.e., no new categories will be added, but if a post doesn't match any of the categories it will be added in the default category--usually "Uncategorized" or "General").
1934
1935 * FEATURE: You can now set global defaults as to whether or not FeedWordPress will update the Link Name and Link Description settings for feeds automatically from the feed title and feed tagline. (By default, it does, as it has in past versions.) Whether this behavior is turned on or off, you can still override the default behavior using feed settings of `hardcode name: yes`, `hardcode name: no`, `hardcode description: yes`, or `hardcode description: no`.
1936
1937 * FEATURE: Users can now provide one or several "aliases" for an author, just as they can for a category. For example, to make FeedWordPress treat posts by "Joseph Cardinal Ratzinger" and "Pope Benedict XVI" as by the same author, edit the user profile for Pope Benedict XVI and add a line like this to the "User profile" field:
1938
1939 a.k.a.: Joseph Cardinal Ratzinger
1940
1941 You can add several aliases, each on a line by itself. You can also add any other text you like to the Profile without interfering with the aliases.
1942
1943 * FEATURE: Users can now choose how to handle syndicated posts that are in unfamiliar categories or by unfamiliar authors (i.e., categories or authors whose names are not yet in the WordPress database). By default, FeedWordPress will (as before) create a new category (or new author) and use it for the current post and any future posts. This behavior can be changed, either for all feeds or for one or another particular feed.
1944
1945 There are now three different options for an unfamiliar author: (1) FeedWordPress can create a new author account and attribute the syndicated post to the new account; (2) FeedWordPress can attribute the post to an author if the author's name is familiar, and to a default author (currently, this means the Site Administrator account) if it is not; (3) FeedWordPress can drop posts by unfamiliar authors and syndicate only posts by authors who are already in the database.
1946
1947 There are, similarly, two different options for an unfamiliar category: (1) FeedWordPress can create new categories and place the syndicated post in them; (2) FeedWordPress can drop the unfamiliar categories and place syndicated posts only in categories that it is already familiar with. In addition, FeedWordPress 0.95 lets you choose whether posts that are in *no* familiar categories should be syndicated (and placed in the default category for the blog) or simply dropped.
1948
1949 You can set the default behavior for both authors and categories using the settings in Options --> Syndication. You can also set different behavior for specific feeds by adding the `unfamiliar author` and / or `unfamiliar categories` settings to the Link Notes section of a feed:
1950
1951 unfamiliar author: (create|default|filter)
1952 unfamiliar categories: (create|default|filter)
1953
1954 A setting of `unfamiliar author: create` will make FeedWordPress create new authors to match unfamiliar author names *for this feed alone*. A setting of `unfamiliar author: default` will make it assign posts from unfamiliar authors to the default user account. A setting of `unfamiliar author: filter` will cause all posts (from this feed alone) to be dropped unless they are by an author already listed in the database. Similiarly, `unfamiliar categories: create` will make FeedWordPress create new categories to match unfamiliar category names *for this feed alone*; `unfamiliar categories: default` will cause it to drop any unfamiliar category names; and `unfamiliar categories: filter` will cause it to *both* drop any unfamiliar category names *and* to only syndicate posts that are placed in one or more familiar categories.
1955
1956 These two new features allow users to do some coarse-grained filtering without having to write a PHP filter. Specifically, they offer an easy way for you to filter feeds by category or by author. Suppose, for example, that you only wanted to syndicate posts that your contributors place in the "Llamas" category. You could do so by setting up your installation of WordPress so that the only category in the database is "Llamas," and then use Options --> Syndication to set "Unfamiliar categories" to "don't create new categories and don't syndicate posts unless they match at least one familiar category". Now, when you update, only posts in the "Llamas" category will be syndicated by FeedWordPress.
1957
1958 Similarly, if you wanted to filter one particular feed so that only posts by (for example) the author "Earl J. Llama" were syndicated to your site, you could do so by creating a user account for Earl J. Llama, then adding the following line to the settings for the feed in Link Notes:
1959
1960 unfamiliar author: filter
1961
1962 This will cause any posts from this feed that are not authored by Earl J. Llama to be discarded, and only the posts by Earl J. Llama will be syndicated. (If the setting is used on one specific feed, it will not affect how posts from other feeds are syndicated.)
