3 +Changes from 2009.0707 to Trunk
4 +-------------------------------
3 5
6 +### Compatibility ###
7 +
8 +* SIMPLEPIE IS NOW USED TO PARSE FEEDS; NO MORE MAGPIERSS UPGRADES NEEDED:
9 + One of the biggest changes in this release is that FeedWordPress no
10 + longer depends on MagpieRSS to parse feeds, and has switched to the much
11 + more up-to-date and flexible SimplePie feed parser, which is included as
12 + a standard part of WordPress versions 2.8 and later. Using SimplePie will
13 + hopefully allow for better handling of feeds going further, and will
14 + allow me greater flexibility in determining how exactly the feed parser
15 + will operate. It also means that FeedWordPress no longer requires
16 + special upgrades to the WordPress core MagpieRSS files, and should
17 + eliminate quite a bit of complexity.
18 +
19 +* MAGPIERSS COMPATIBILITY LAYER FOR EXISTING FILTERS AND ADD-ONS: However,
20 + I have also implemented a compatibility layer to ensure that existing
21 + filters and add-ons for FeedWordPress which depended on the MagpieRSS
22 + data format *should not be broken* by the switch to SimplePie. Going
23 + forward, I recommend that new filters and add-ons be written to take
24 + advantage of the SimplePie object representations of items, feeds, etc.,
25 + rather than the MagpieRSS arrays, but the MagpieRSS arrays will still
26 + be available and older filters should continue to work as they have in
27 + the past.
28 +
29 +* COMPATIBILITY WITH WORDPRESS 2.9.x and 3.0: This release has been tested
30 + for the existing WordPress 2.9.x branch and with the upcoming release of
31 + WordPress 3.0. Changes in the user interface JavaScript between WordPress
32 + 2.8.x and WordPress 2.9 caused the tag box interface element to break in
33 + the Syndication --> Categories & Tags settings page; changes in the API
34 + functions for adding new authors caused fatal errors under certain
35 + conditions in WordPress 3.0. These breakages have been fixed.
36 +
37 +* DROPPED LEGACY SUPPORT FOR WORDPRESS PRIOR TO 2.8: Because SimplePie is
38 + not included with versions of WordPress prior to 2.8, I have chosen to
39 + drop legacy support for WordPress versions 1.5 through 2.7. If you are
40 + using FeedWordPress with a version of WordPress before 2.8, you will
41 + have to upgrade your installation of WordPress in order to take
42 + advantage of this release.
43 +
44 +* PHP 5.3 COMPATIBILITY: A couple of compatibility issues, which were
45 + causing fatal errors amd ugly warnings for users of PHP 5.3,
46 + have been eliminated.
47 +
48 +### Features and Processing ###
49 +
50 +* INTERFACE REORGANIZATION: The interface restructuring, began with
51 + Version 2009.0612, has been completed. Catch-all settings pages have
52 + been eliminated entirely for pages that cover each aspect of handling
53 + a feed: Feeds & Updates, Posts & Links, Authors, Categories & Tags,
54 + and Back End handling of the database and diagnostic information.
55 + Extensive new interface hooks allow add-on modules to significantly
56 + change or extend the FeedWordPress admin interface and workflow.
57 +
58 +* STORING INFORMATION FROM THE FEED IN CUSTOM FIELDS: Many users
59 + have written to request the ability to store information from elements
60 + in the feed in a custom field on each post. (So that, for example, if
61 + post includes a `itunes:duration` element, you could store the contents
62 + in a Custom Field called `duration` on the post (for a Theme to access
63 + later). The Custom Post Settings under Syndication --> Posts & Links now
64 + allow you to access any item or feed tag, using a syntax similar to
65 + a much-simplified version of XPath. See Posts & Links settings for
66 + details.
67 +
68 +* UPDATE-FREEZING ON MANUALLY EDITED POSTS: FeedWordPress now allows you
69 + to mark posts that have been manually edited, so that the changes you
70 + make will not be overwritten by later updates from the feed. If you make
71 + manual edits to a particular post, just check the "Manual editing"
72 + checkbox in order to protect your changes from being overwritten. If you
73 + want to block *all* posts from being updated after they are imported
74 + for the first time, a new "Updated Posts" setting in Posts & Links
75 + allows you to freeze all posts from a particular feed, or all syndicated
76 + posts.
77 +
78 +* SETTING: FEED-BY-FEED SETTINGS FOR WHERE PERMALINKS POINT TO: You've
79 + always been able to tell FeedWordPress whether permalinks for posts
80 + should point to the original source of the story or the local copy. Now
81 + you can choose different policies for different feeds, instead of one
82 + global policy for all feeds. (Of course, you can still use a global
83 + default if you prefer.)
84 +
85 +* SETTING: USER CONTROL OVER TIMING BASIS. You can now determine the
86 + schedule on which feeds are considered ready to poll for updates --
87 + by default feeds become ready for polling after about 1 hour. You can
88 + now increase or decrease the time window under Syndication --> Feeds &
89 + Updates. (However, please pay *CAREFUL ATTENTION* to the recommendations
90 + and DO NOT set the scheduling lower than 60 minutes unless you are
91 + ABSOLUTELY SURE that you have specific permission from webmaster who
92 + provides that specific feed to poll more frequently than that. If you
93 + set this too low (and about 60 minutes is the polite minimum if you
94 + haven't been given a different figure), most webmasters will consider
95 + the frequent hits on their server as rude, or even downright abusive.
96 +
97 +* OTHER SETTINGS: New settings also include the ability to stop FWP from
98 + resolving relative URLs within syndicated content, and the ability to
99 + choose whether FeedWordPress should indicate the comment feed from the
100 + original source, or the local comment feed, when providing the comment
101 + feed URL for a syndicated post.
102 +
103 +### PARSING ###
104 +
105 +* BETTER DATE HANDLING -- FEWER FLASHBACKS TO 1969 and 1970: FeedWordPress
106 + has made some bugfixes and some improvements in the logic for parsing
107 + dates. This should allow FeedWordPress to correctly parse more dates in
108 + more feeds; and, in the last resort, when FeedWordPress fails to
109 + correctly parse a date, to fall back to a more intelligent default. This
110 + should hopefully avoid most or all error conditions that have resulted
111 + in articles being erroneously dated to the dawn of the Unix epoch
112 + (31 December 1969 or 1 January 1970).
113 +
114 +* FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Based on a straightforward
115 + reading of the existing RSS specs, it's reasonable for the
116 + rss:description element to be read as a plaintext summary or excerpt for
117 + the item containing the description -- with the full text of the item,
118 + if available, in another, better-suited element, such as the de facto
119 + standard content:encoded extension element. The problem is that uses of
120 + RSS rarely have much to do with anything like a straightforward reading
121 + of the specs. As a result, many actual RSS producers in the wild put the
122 + full text of the article in a description element. But since
123 + FeedWordPress has treated this text as a summary, this produces
124 + aggregated posts with lengthy "excerpts" containing the full text of the
125 + article. This release of FeedWordPress fixes the problem by doing a
126 + little digging before treating rss:description as a summary: if the
127 + description element is used properly as a plain text summary, then
128 + FeedWordPress will take the summary provided by the feed, rather than
129 + recreating its own excerpt from the full text; but if an RSS item has no
130 + full-text element other than description, FeedWordPress will treat the
131 + description element as the full text of the article, and generate a
132 + shortened excerpt automatically from that text.
133 +
134 +### API ###
135 +
136 +* TEMPLATE API: new template tags `get_local_permalink()` and
137 + `the_local_permalink()` allow you to access the permalink for a post on
138 + your aggregator site, even when FeedWordPress is rewriting permalinks to
139 + point to the original source site.
140 +
141 +* NEW HOOKS FOR ADD-ONS AND FILTERS: I have added a number of new hooks
142 + which allow add-on modules to filter more precisely, gather information
143 + at more points, and to enhance the FeedWordPress admin interface. For
144 + a list of new hooks and documentation, see the FeedWordPress
145 + documentation wiki at
146 + <http://feedwordpress.radgeek.com/wiki/add-ons-and-filters>
147 +
148 +* FILTER API: A number of new utility methods have been added to the
149 + SyndicatedPost class to make it easier for filters and add-ons to
150 +
151 +* FILTER API: Globals $fwp_channel and $fwp_feedmeta DEPRECATED. These
152 + global variables, originally introduced to allow filters access to
153 + information about the source feed in `syndicated_item` filters (which
154 + were passed in through global variables rather than as parameters
155 + because of a bug in WP 1.5 which was then fixed in 1.5.1) have been
156 + DEPRECATED. If you have any filters or add-ons which still depend on
157 + these global variables, you should see about fixing them to access data
158 + about the source feed using the SyndicatedPost::link element instead.
159 + For documentation, see the FeedWordPress documentation wiki at
160 + <http://feedwordpress.radgeek.com/wiki/syndicatedpost> and
161 + <http://feedwordpress.radgeek.com/wiki/syndicatedlink>.
162 +
163 +* DIAGNOSTICS: I've included a number of new diagnostic options and
164 + messages, which should allow an experienced user to better investigate
165 + any problems that may crop up.
166 +
167 +### Bug Fixes ###
168 +
169 +* BUGFIX: & IN PERMALINKS NO LONGER CAUSING ATOM OR HTML VALIDATION
170 + EFFORTS: Many users reported an issue in which syndicating a feed with
171 + special XML characters in the URLs (& was the most common, since it is
172 + used to separate HTTP GET parameters) would cause the aggregator's
173 + feeds to produce invalid (malformed) XML. This update addresses the
174 + issue in Atom feeds. Unfortunately, it has not been technically possible
175 + to address the problem in RSS 2.0 feeds, due to limitations on
176 + WordPress's internal templates for RSS feeds.
177 +
178 +* BUGFIX: BROKEN URLS IN "POPULAR POSTS" AND SIMILAR PLUGINS SHOULD NO
179 + LONGER BE BROKEN. A number of users noticed an issue where plugins and
180 + templates that listed posts in locations outside of the post loop
181 + (for example, "Popular Posts"-style plugins that listed posts in the
182 + sidebar), often produced the wrong URL for post links. (Typically, all
183 + the posts listed would get the same wrong URL.) This should now be
184 + fixed. Thanks to Björn for sending in a quick fix!
185 +
186 +* MINOR BUGFIXES: This release includes a number of fixes to minor bugs
187 + and compatibility issues, including: silent failures of the "Syndicate"
188 + button, "Illegal Offset Type" error messages from MagpieRSS,
189 +
190 +
191 +Changes from 2009.0618 to 2009.0707
192 +-----------------------------------
193 +* BUGFIX: WORDPRESS 2.8 AJAX COMPATIBILITY ISSUES RESOLVED (blank or
194 + truncated "Syndicated Sites" administration page): Due to changes in the
195 + AJAX interface elements between WordPress 2.7 and WordPress 2.8, several
196 + FeedWordPress users encountered an issue where the front "Syndication"
197 + page in the FeedWordPress administrative interface would come up blank,
198 + without the normal "Syndicated Sites" list and "Update" control, or
199 + sometimes wth the boxes visible but one or both of them truncated, with
200 + only the title bar. This issue should now be resolved: with the new
201 + version of FeedWordPress, the compatibility issue that caused the
202 + disappearance should be eliminated, and if boxes are shown with only
203 + their handle visible, you should once again be able to drop down the
204 + rest of the box by clicking once on its title bar.
205 +
206 +* BUGFIX: TAG SETTING WIDGET FIXED. Due to changes in interface elements
207 + between WordPress 2.7 and WordPress 2.8, people using FeedWordPress with
208 + WordPress 2.8 found that the widget for setting tags to be applied to
209 + all syndicated posts, or all syndicated posts from a particular feed,
210 + no longer displayed "Add" and "Remove" buttons for individual tags. This
211 + issue has now been fixed, and the tagging widget should once again work
212 + more or less exactly like the tagging widget for individual posts in the
213 + normal WordPress admin interface.
214 +
215 +Changes from 2009.0613 to 2009.0618
216 +-----------------------------------
217 +* BUGFIX: MYSTERY ERRORS WITH WITH WP_Http_Fsockopen HTTP TRANSPORT
218 + ELIMINATED: Thanks to a combination of a subtle bug in FeedWordPress,
219 + and changes to the HTTP transport code in WordPress, a number of users
220 + encountered an error in which any time they attempted to add a new feed
221 + through the FeedFinder interface, FeedWordPress would fail and display
222 + an HTTP request failure diagnostic message. The subtle bug has been
223 + fixed, and with it, most of these errors should now be eliminated.
224 +
225 + Be sure to upgrade your MagpieRSS to the most recent MagpieRSS version
226 + after you have insalled FeedWordPress 2009.0618, or this bug fix will
227 + not take effect.
228 +
229 +
230 +Changes from 2009.0612 to 2009.0613
231 +-----------------------------------
232 +* INTERFACE/BUGFIX: WORDPRESS 2.8 CATEGORY BOX FIX. Thanks to a subtle
233 + change in class names between the WordPress 2.7 and 2.8 stylesheets,
234 + category boxes in the FeedWordPress settings interface tended to overflow
235 + and have a lot of messy-looking overlapping text under WordPress 2.8.
236 + This has now been fixed.
237 +
238 +* FeedFinder FAILURE DIAGNOSTICS: When FWP's FeedFinder fails to find any
239 + feeds at a given URL (for example, when you are trying to add a
240 + subscription through the administrative interface and you run into an
241 + error message), FeedWordPress now provides more diagnostic information
242 + for the reasons behind the failure. If that helps you, great; if not,
243 + it should help me respond more intelligently to your support request..
244 +
245 +Changes from 2008.1214 to 2009.0612
246 +-----------------------------------
247 +* WORDPRESS 2.8 COMPATIBILITY: FeedWordPress 2009.0612 has been tested for
248 + compatibility with the recent version 2.8 release of WordPress.
249 +
250 +* INTERFACE RESTRUCTURING: In order to avoid settings posts from becoming
251 + too crowded, and to modularize and better organize the user interface,
252 + new "Posts" and "Categories & Tags" subpages have been created under the
253 + "Syndication" menu. "Posts" controls settings for individal syndicated
254 + posts (such as publication status, comment and ping status, whether or
255 + not to use the original location of the post as the permalink, whether
256 + or not to expose posts to formatting filters, and so on). "Categories &
257 + Tags" controls settings for assigning new syndicated posts to categories
258 + and tags, such as categories or tags to apply to all syndicated posts,
259 + and how to handle categories that do not yet exist in the WordPress
260 + database. These subpages, like the Authors subpage, handle settings for
261 + the global default level and for individual syndicated feeds.
262 +
263 + Corresponding to these new subpages, the old Syndication Settings and
264 + Feed Settings subpages have been cleaned up and simplified, and now only
265 + link to the appropriate subpages for options that can be set in the
266 + Posts, Authors, or Categories & Tags subpages.
267 +
268 +* FEATURE: ADD CUSTOM SETTINGS TO EACH SYNDICATED POST: FeedWordPress has
269 + long had an interface for creating custom settings for each syndicated
270 + *feed* which could be retrieved in templates using the `get_feed_meta()`
271 + template function. But it had no feature for adding custom fields to
272 + each individual syndicated *post*. In response to requests from users, I
273 + have added the ability to apply custom fields to each individual
274 + syndicated post, using the new Syndication --> Posts subpage. You can
275 + set up custom fields to be applied to every syndicated post, or custom
276 + fields to be applied to syndicated posts from a particular feed.
277 +
278 +* FEATURE: MAGPIERSS VERSION CHECK AND UPGRADE: FeedWordPress will attempt
279 + to determine whether or not you are using the upgraded version of
280 + MagpieRSS that comes packaged with FeedWordPress. If not, it will throw
281 + an error on admin pages, and, if you are a site administrator, it will
282 + give you the option to ignore the error message, or to attempt an
283 + automatic upgrade (using a native file copy). If the file copy fails,
284 + FeedWordPress will offer some guidance on how to perform the upgrade
285 + manually.
286 +
287 +* BLANK POSTS PROBLEM NO LONGER OCCURS WITH OLD & BUSTED MAGPIERSS: Due
288 + to the fact that I relied on a content normalization that occurs in my
289 + upgraded version of MagpieRSS, but not in the old & busted version of
290 + MagpieRSS that ships with WordPress, until this version, if you tried to
291 + syndicate an Atom feed without having performed the (*strongly
292 + recommended*) MagpieRSS upgrade, all of the posts would come up with
293 + completely blank contents. That's not because MagpieRSS couldn't read
294 + the data, but rather because the new Magpie version puts that data in a
295 + location where the old version doesn't, and I was only looking in that
296 + newer location. Now it checks for both, meaning that posts will continue
297 + to display their contents even if you don't upgrade MagpieRSS. (But you
298 + **really should** upgrade it, anyway.)
299 +
300 +* BUGFIX: RELATIVE URI RESOLUTION FOR POST CONTENT RESTORED. Some time
301 + back, I added support for resolving relative URIs against xml:base on
302 + feeds that support it to the MagpieRSS upgrade in FeedWordPress. Then I
303 + took out code that did the same thing from the main FeedWordPress code.
304 + Of course, the problem is that some people, even though it is clearly
305 + stupid or evil to do so, still include relative URIs for images or links
306 + in posts on feed formats that do *not* adequately support xml:base
307 + (notably, RSS 2.0 feeds). In response to a user request, I have added
308 + this functionality back in, so that MagpieRSS will resolve any relative
309 + URIs that it knows how to resolve using xml:base, and then FeedWordPress
310 + will attempt to resolve any relative URIs that are left over afterwards.
311 +
312 +* BUGFIX: INTERFACE OPTION FOR SETTING SYNDICATED POST PUBLICATION STATUS
313 + ON A FEED-BY-FEED BASIS HAS BEEN RESTORED: Due to a version-checking
314 + bug, users of WordPress 2.7.x lost an option from the "Edit a syndicated
315 + feed" interface which allowed them to determine whether newly syndicated
316 + posts should be published immediately, held as "Pending Review," saved
317 + as drafts, or saved as private posts. (The option to change this
318 + setting globally remained in place, but users could no longer set it on
319 + a feed-by-feed basis.) The version-checking bug has been fixed, and the
320 + option has been restored.
321 +
322 +* BUGFIX: "ARE YOU SURE?" FATAL ERROR ELIMINATED AND SECURITY IMPROVED:
323 + Under certain circumstances (for example, when users have configured
324 + their browser or proxy not to send HTTP Referer headers, for privacy or
325 + other reasons), many features in the FeedWordPress administrative
326 + interface (such as adding new feeds or changing settings) would hit a
327 + fatal error, displaying only a cryptic message reading "Are you sure?"
328 + and a blank page following it. This problem has been eliminated by
329 + taking advantage of WordPress's nonce functions, which allow the
330 + security check which ran into this error to work properly even without
331 + receiving an HTTP Referer header. (N.B.: WordPress's nonce functions
332 + were first introduced in WordPress 2.0.3. If you're using FeedWordPress
333 + with an older version of WordPress, there's no fix for this problem:
334 + you'll just need to turn Referer headers back on. Sorry.)
335 +
336 +* BUGFIX: MANUALLY-ALTERED POST STATUS, COMMENT STATUS, AND PING STATUS NO
337 + LONGER REVERTED BY POST UPDATES: If you manually altered the post status,
338 + comment status, or ping status of a syndicated post from what it was set
339 + to when first syndicated -- for example, if you had a feed that was set
340 + to bring in new posts as "Pending Review," and you then marked some of
341 + the pending posts as "Published" and others as "Unpublished" -- then
342 + in previous versions of FeedWordPress, these manual changes to the
343 + status would be lost -- so that, for example, your Published or Unpublished
344 + articles would revert to Pending Review -- if the source feed made any
345 + upates to the item. This could make the Pending Review feature both
346 + unreliable and also extremely frustrating to work with. The good news is
347 + that this bug has since been fixed: if you manually update the status
348 + of a post, it will no longer be reverted if or when the post is updated.
349 +
350 +* BUGFIX: OCCASIONAL FATAL ERROR ON UPDATE ELIMINATED: Under certain
351 + limited conditions (specifically, when both the title and the content of
352 + a post to be updated are empty), an attempt to update the post would
353 + result in a fatal error. This has been fixed.
354 +
355 +* INTERFACE: "CONFIGURE SETTINGS" CONVENIENCE LINK ADDED TO CONFIRMATION
356 + MESSAGE WHEN A NEW FEED IS ADDED: When you add a new subscription to
357 + FeedWordPress, the message box that appears to confirm it now includes a
358 + handy link to the feed's settings subpage, so that you can quickly set
359 + up any special settings you may want to set up for the new feed, without
360 + having to hunt through the list of all your other subscriptions to pick
361 + out the new one.
362 +
363 +* INTERFACE: SIMPLIFYING AND CLARIFYING AUTOMATIC UPDATES SETTINGS. I have
364 + removed an interval setting for the cronless automatic updates which has
365 + confused many FeedWordPress users. In past versions of FWP, when you
366 + turned on automatic updates, you would be presented with a time interval
367 + setting which controlled how often FeedWordPress would check for feeds
368 + ready to be polled for updates. (That is, it DID NOT control how often
369 + feeds *would be polled*; it controlled how often FeedWordPress would
370 + *check* for feeds that *had become ready to poll*. The schedule on which
371 + feeds became ready for polling was still controlled either by requests
372 + encoded in elements within the feed itself, or else according to an
373 + internal calculation within FeedWordPress, averaging out to about 1 hour,
374 + if the feed did not include any scheduling request elements.) Since many
375 + users very often (and understandably) confused the purpose of this
376 + setting, and since the setting is for a feature that's actually very
377 + unlikely to require any manual control by the user, I have removed the
378 + setting; FeedWordPress now simply uses the default value of checking for
379 + feeds to poll every 10 minutes.
380 +
381 +* FEEDFINDER PERFORMANCE IMPROVEMENT: FeedWordPress's FeedFinder class
382 + now uses `array_unique()` to make sure that it doesn't waste time
383 + repeatedly iterating over and polling the same URI. Props to Camilo
384 + (<http://projects.radgeek.com/2008/12/14/feedwordpress-20081214/#comment-20090122160414>).
385 +
386 +Changes from 2008.1105 to 2008.1214
387 +-----------------------------------
388 +
389 +* WORDPRESS 2.7 COMPATIBILITY: FeedWordPress has been tested for
390 + compatibility with the newly released WordPress 2.7. WordPress 2.7 has
391 + deprecated the Snoopy library for HTTP requests, which caused a fatal
392 + error for users who had not installed the MagpieRSS upgrade (or whose
393 + installation of the MagpieRSS upgrade was overwritten by a recent update
394 + of WordPress). FeedWordPress now handles things gracefully when Snoopy
395 + is not immediately available.
396 +
397 +* INTERFACE SPIFFED UP: Interface elements have been updated so that
398 + FeedWordPress's management interface fits in more naturally with the
399 + WordPress 2.7 interface (including a new logo and a number of small
400 + interface tweaks).
401 +
402 +* BUG WITH TAGS FOR SYNDICATED ARTICLES FIXED: Several users encountered a
403 + bug with the option to add tags to all syndicated posts under
404 + Syndication --> Settings -- if you told FeedWordPress to add more than
405 + one tag to all syndicated posts, instead of doing so correctly, it would
406 + add a *single* tag instead, whose name was composed of the names of all
407 + the tags you asked it to add. This bug was the result of nothing more
408 + dignified than a typographical error on my part. It has now been fixed.
409 +
410 +* MORE INFORMATION AVAILABLE WHEN FEEDWORDPRESS CAN'T FIND A FEED: When
411 + you enter a URL for a new syndication source, FeedWordPress uses a
412 + simple feed-finding algorithm (originally based on Mark Pilgrim's
413 + Universal Feed Finder) to try to determine whether the URL is the URL
414 + for a feed, or, if the URL points to an ordinary website rather than to
415 + a feed, whether there is a feed for that website. All well and good, but
416 + if FeedWordPress failed to find a feed, for whatever reason, it would
417 + typically return nothing more than a nasty little note to the effect of
418 + "no feed found," without any explanation of what went wrong.
419 + FeedWordPress now keeps track of error conditions from the HTTP
420 + requests that it uses in the course of looking for the feed, and so may
421 + be able to give you a bit more information about the nature of the
422 + problem if something goes wrong.
423 +
424 +
425 +Changes from 2008.1101 to 2008.1105
426 +-----------------------------------
427 +
428 +* INTERFACE RESTRUCTURING AND SYNDICATION --> AUTHORS PAGE: As a first
429 + step towards modularizing and better organizing the user interface, a
430 + new "Authors" subpage has been created under the Syndication menu, which
431 + controls settings for syndicated authors, both at the global default
432 + level and at level of individual syndicated feeds.
433 +
434 +* BUG RELATED TO THE ATTRIBUTION OF POSTS TO THE WRONG AUTHOR FIXED: Some
435 + users encountered an issue in which posts by different authors on
436 + different blogs -- especially blogs generated by Blogger -- were
437 + mistakenly attributed to a single author. The problem was caused by the
438 + way in which FeedWordPress matches syndicated authors to user accounts
439 + in the WordPress database: normally, if two feeds each list an author
440 + with the same e-mail address, they are counted as being the same person.
441 + Normally this works well, but it creates an issue in cases where
442 + blogging software assigns a single anonymous e-mail address to users who
443 + do not want their real e-mail address published. This is, for example,
444 + what Blogger does (by giving all users a default e-mail address of
445 + <noreply@blogger.com> if they don't want their own e-mail address
446 + listed). FeedWordPress now allows the user to correct for this problem
447 + with a couple of new settings under **Syndication --> Authors**, which
448 + allow users to turn off e-mail based author matching for particular
449 + addresses, or, if desired, to turn it off entirely. By default, e-mail
450 + based author matching is still turned on, but disabled for a list of
451 + known generic e-mail addresses. Right now, the "list" consists entirely
452 + of <noreply@blogger.com>; if you know other addresses that should be
453 + added, please [contact me](http://radgeek.com/contact) to let me know.
454 +
455 + Please note that if you have already encountered this issue on your
456 + blog, upgrading FeedWordPress will prevent it from re-occurring in the
457 + future, but you still need to do two other things to fix the existing
458 + problem on your blog.
459 +
460 + First, for each feed where posts have been mis-attributed, you need to
461 + change the existing author mapping rules to re-map a a syndicated
462 + author's name to the proper target account. Go to **Syndication -->
463 + Authors**, select the feed you want to change from the drop-down list,
464 + and then change the settings under the "Syndicated Authors" section.
465 + (You will probably need to select "will be assigned to a new user..." to
466 + create a new user account with the appropriate name.)
467 +
468 + Second, for each feed where posts have been mis-attributed, you need to
469 + re-assign already-syndicated posts that were mis-attributed to the
470 + correct author. You can do that from **Syndication --> Authors** by
471 + using the author re-assignment feature, described below.
472 +
473 +* AUTHOR RE-ASSIGNMENT FOR A PARTICULAR FEED: The author settings page
474 + for each syndicated feed, under **Syndication --> Authors**, now
475 + includes an section titled "Fixing mis-matched authors," which provides
476 + an interface for re-assigning or deleting all posts attributed to a
477 + particular author on a particular feed.
478 +
479 +* SUPPORT FOR `<atom:source>` ELEMENT IN SYNDICATED FEEDS: Some feeds
480 + (for example, those produced by FeedWordPress) aggregate content from
481 + several different sources, and include information about the original
482 + source of the post in an `<atom:source>` element. A new setting under
483 + **Syndication --> Options** allows you to control what FeedWordPress
484 + will report as the source of posts syndicated from aggregator feeds in
485 + your templates and feeds: you can have FeedWordPress report that the
486 + source of a post is the aggregator feed itself, or you can have it
487 + report that the source of a post is the original source that the
488 + aggregator originally syndicated the post from.
489 +
490 + By default, FeedWordPress will report the aggregator, not the original
491 + source, as the source of a syndicated item.
492 +
493 +* LOAD BALANCING AND TIME LIMITING FEATURES FOR UPDATES: Some users have
494 + encountered issues due to running up against PHP execution time limits
495 + during the process of updating large syndicated feeds, or a very large
496 + set of syndicated feeds. FeedWordPress now has a feature that allows you
497 + to limit the total amount of time spent updating a feed, through the
498 + "Time limit on updates" setting under **Syndication --> Options**. By
499 + turning on this setting and adjusting the time limit to a low enough
500 + figure to avoid your PHP installation's time-out setting. (PHP execution
501 + time limits are usually in the vicinity of 30 seconds, so an update
502 + time limit of 25 seconds or so should provide plenty of time for updates
503 + while allowing a cushion of time for other, non-update-related functions
504 + to do their work.)
505 +
506 + If feed updates are interrupted by the time limit, FeedWordPress uses
507 + some simple load balancing features to make sure that updates to other
508 + feeds will not be blocked by the time-hogging feed, and will also make
509 + sure that when the interrupted update is resumed, FeedWordPress will
510 + skip ahead to resume processing items at the point at which it was
511 + interrupted last time, so that posts further down in the feed will
512 + eventually get processed, and not get blocked by the amount of time it
513 + takes to process the items higher up in the feed.
514 +
515 +* `guid` INDEX CREATION BUTTON: FeedWordPress frequently issues queries on
516 + the `guid` column of the WordPress posts database (since it uses post
517 + guid URIs to keep track of which posts it has syndicated). In very large
518 + FeedWordPress installations, you can often significantly improve
519 + performance by creating a database index on the `guid` column, but
520 + normally you would need to poke around with MySQL or a tool like
521 + phpMyAdmin to do this. FeedWordPress can now save you the trouble: to
522 + create an index on the `guid` column, just go to
523 + **Syndication --> Options**, and mash the button at the bottom of the
524 + "Back End" section.
525 +
526 +Changes from 2008.1030 to 2008.1101
527 +-----------------------------------
528 +
529 +* INTERFACE BUG THAT PREVENTED ADDING NEW SITES FIXED: The UI reforms in
530 + FWP 2008.1030 unintentionally introduced a bug that prevents clean
531 + installations of FeedWordPress from providing an input box for adding
532 + new feeds to the list of syndicated feeds. This bug has been fixed.
533 +
534 +Changes from 0.993 to 2008.1030
535 +-------------------------------
536 +
537 +* WORDPRESS 2.6 COMPATIBILITY: FeedWordPress should now be compatible with
538 + WordPress 2.6, and should work more or less seamlessly with the new post
539 + revision system. A bug which caused multiple new revisions to be created
540 + for posts on certain feeds, regardless of whether or not the item had
541 + been updated, has been fixed.
542 +
543 +* INTERFACE IMPROVEMENTS: The user interface has been substantially
544 + restyled to fit in better with the visual style of WordPress 2.5 and
545 + 2.6.
546 +
547 +* YOUTUBE BUG FIXED: POSTS SYNDICATED THROUGH AN AUTOMATIC UPDATE ARE NO
548 + LONGER STRIPPED OF `<OBJECT>` TAGS AND CERTAIN OTHER HTML ELEMENTS: Due
549 + to the way that some versions of WordPress process posts that are
550 + inserted into the database when no user is logged in, many users
551 + experienced an issue where YouTube videos and other content using the
552 + HTML `<object>` tag would be stripped out of posts that were syndicated
553 + during an automatic update. (Posts that were syndicated through manual
554 + updates from within the WordPress Dashboard were not affected, because
555 + the issue does not arise when an update is executed under a logged-in
556 + administrator's credentials.) This bug has now been fixed; YouTube
557 + videos and other content using `<object>` tags should now appear
558 + properly in syndicated posts, regardless of the way in which the post
559 + was syndicated.
560 +
561 +* AJAX BUGS FIXED: Bugs which blocked the normal operation of WordPress
562 + 2.5's AJAX interface elements when FeedWordPress was activated have been
563 + fixed.
564 +
565 +* TAG SUPPORT: A couple of features have been introduced to take advantage
566 + of the tagging features in WordPress 2.3.x, 2.5.x, and 2.6.x. Now, when
567 + unfamiliar categories are encountered for posts on a feed, you can
568 + choose for FeedWordPress (1) to drop the category; (2) to drop the
569 + category and to filter out any post that does not match at least one
570 + familiar category; (3) to create a new category with that name, or,
571 + now, you can also have FeedWordPress (4) create a new *tag* with that
572 + name. This option can be set site-wide under Syndication --> Options,
573 + or it can be set on a feed-by-feed basis in a feed's Edit screen.
574 +
575 + In addition, you can now set particular tags to apply to all incoming
576 + syndicated posts, under Syndication --> Options, or you can set tags
577 + to apply to all incoming syndicated posts from a particular feed in that
578 + feed's Edit screen.
579 +
580 +* FORMATTING FILTERS: There is a new option available under Syndication ->
581 + Options which allows users to choose whether or not to expose syndicated
582 + posts to being altered by formatting filters. By default, FeedWordPress
583 + has always protected syndicated posts (which are already in display-ready
584 + HTML when they are syndicated) from being reformatted by formatting
585 + filters. However, this approach means that certain plugins which depend
586 + on formatting filters (for example, to add "Share This" bars or relevant
587 + links to the end of a post) are blocked from working on any syndicated
588 + posts. If you want to use one of these plugins together with
589 + FeedWordPress, you can now do so by changing the "Formatting Filters"
590 + setting from "Protect" to "Expose."
591 +
592 +* `<atom:source>` ELEMENTS NOW INCLUDED IN ATOM FEED: Atom 1.0 provides
593 + a standard method for aggregators to indicate information about the original source of
594 + a syndicated post, using the `<atom:source>` element. FeedWordPress now
595 + introduces standard `<atom:source>` elements including the title, homepage, and
596 + feed URI of the source from which a syndicated post was syndicated. Cf.
597 + <http://www.atomenabled.org/developers/syndication/atom-format-spec.php#element.source>
598 +
599 +* MODULARIZATION OF CODE: The code for different elements of FeedWordPress
600 + has been broken out into several modules for easier inspection,
601 + documentation, and maintenance of the code.
602 +
603 +* VERSIONING SCHEME CHANGED: FeedWordPress's feature set has proven stable
604 + enough that it can now be removed from beta status; a good thing, since
605 + I was very quickly running out of version numbers to use. New releases
606 + of FeedWordPress will have version numbers based on the date of their
607 + release.
608 +
609 +Changes from 0.992 to 0.993
610 +---------------------------
611 +
612 +* WORDPRESS 2.5.1 COMPATIBILITY: FeedWordPress should now be compatible
613 + with WordPress 2.5.1.
614 +
615 +* WORDPRESS 2.5 INTERFACE IMPROVEMENTS: FeedWordPress's Dashboard
616 + interface has undergone several cosmetic changes that should help it
617 + integrate better with the WordPress Dashboard interface in WordPress
618 + version 2.5.x.
619 +
620 +* SYNDICATED POSTS CAN BE MARKED AS "PENDING REVIEW": WordPress 2.3 users
621 + can now take advantage of WordPress's new "Pending Review" features for
622 + incoming syndicated posts. Posts marked as "Pending Review" are not
623 + published immediately, but are marked as ready to be reviewed by an
624 + Administrator or Editor, who can then choose to publish the post or
625 + hold it back. If you want to review syndicated posts from a particular
626 + feed, or from all feeds, before they are posted, then use
627 + Syndication --> Syndicated Sites --> Edit or Syndication --> Options to
628 + change the settings for handling new posts.
629 +
630 +* AWARE OF NEW URI FOR del.icio.us FEEDS: Previous releases of
631 + FeedWordPress already automatically split del.icio.us tags up
632 + appropriately appropriately when generating categories. (del.icio.us
633 + feeds smoosh all the tags into a single `<dc:subject>` element,
634 + separated by spaces; FeedWordPress un-smooshes them into multiple
635 + categories by separating them at whitespace.) Unfortunately, del.icio.us
636 + recently broke the existing behavior by changing host names for their
637 + feeds from del.icio.us to feeds.delicious.com. Version 0.993 accounts
638 + for the new host name and un-breaks the tag splitting.
639 +
640 +Changes from 0.991 to 0.992
641 +---------------------------
642 +* AUTHOR RE-MAPPING: FeedWordPress now offers considerable control over
643 + how author names on a feed are translated into usernames within the
644 + WordPress database. When a post by an unrecognized author comes in,
645 + Administrators can now specify any username as the default username to
646 + assign the post to by setting the option in Syndication --> Options
647 + (formerly FeedWordPress only allowed you to assign such posts to user
648 + #1, the site administrator). Administrators can also create re-mapping
649 + rules for particular feeds (under Syndication --> Syndicated Sites -->
650 + Edit), so that (for example) any posts attributed to "Administrator"
651 + on the feed <http://praxeology.net/blog/feed/> will be assigned to
652 + a user named "Roderick T. Long," rather than a user named
653 + "Administrator." These settings also allow administrators to filter out
654 + posts by particular users, and to control what will happen when
655 + FeedWordPress encounters a post by an unrecognized user on that
656 + particular feed.
657 +
658 +* BUG RELATED TO URIS CONTAINING AMPERSAND CHARACTERS FIXED: A bug in
659 + WordPress 2.x's handling of URIs in Blogroll links created problems for
660 + updating any feeds whose URIs included an ampersand character, such as
661 + Google News RSS feeds and other feeds that have multiple parameters
662 + passed through HTTP GET. If you experienced this bug, the most likely
663 + effect was that FeedWordPress simply would not import new posts from a
664 + feed when instructred to do so, returning a "0 new posts" response. In
665 + other cases, it might lead to unpredictable results from feed updates,
666 + such as importing posts which were not contained in the feed being
667 + syndicated, but which did appear elsewhere on the same website. This bug
668 + has, hopefully, been resolved, by correcting for the bug in WordPress.
669 +
670 +Changes from 0.99 to 0.991
671 +--------------------------
672 +* WORDPRESS MU COMPATIBILITY: FeedWordPress should now be compatible with
673 + recent releases of WordPress MU. Once FeedWordPress is made available
674 + as a plugin, each individual blog can choose to activate FeedWordPress
675 + and syndicate content from its own set of contributors.
676 +
677 +* DISPLAY OF MAGPIE WARNINGS: A number of MagpieRSS warnings or error
678 + messages that were displayed when performing an automatic update are
679 + no longer displayed, unless debugging parameters have been explicitly
680 + enabled.
681 +
682 +* BUG RELATED TO INTERNATIONAL CHARACTERS IN AUTHOR NAMES FIXED: Due to a
683 + subtle incompatability between the way that FeedWordPress generated new
684 + user information, and the way that WordPress 2.0 and later added new
685 + authors to the database, FeedWordPress might end up creating duplicate
686 + authors, or throwing a critical error message, when it encountered
687 + authors whose names included international characters. This
688 + incompatability has now been fixed; hopefully, authors with
689 + international characters in their names should now be handled properly.
690 +
691 +* `<media:content>` BUG IN MAGPIERSS FIXED: A bug in MagpieRSS's handling
692 + of namespaced elements has been fixed. Among other things, this bug
693 + caused items containing a Yahoo MediaRSS `<media:content>` element (such
694 + as many of the feeds produced by wordpress.com) to be represented
695 + incorrectly, with only a capital "A" where the content of the post
696 + should have been. Feeds containing `<media:content>` elements should now
697 + be syndicated correctly.
698 +
699 +* update_feedwordpress PARAMETER: You can now use an HTTP GET parameter
700 + (`update_feedwordpress=1`) to request that FeedWordPress poll its feeds
701 + for updates. When used together with a crontab or other means of
702 + scheduling tasks, this means that you can keep your blog automatically
703 + updated on a regular schedule, even if you do not choose to use the
704 + cron-less automatic updates option.
705 +
706 +* Some minor interface-related bugs were also fixed.
707 +
708 +
709 +Changes from 0.981 to 0.99
710 +--------------------------
711 +Version 0.99 adds several significant new features, fixes some bugs, and
712 +provides compatability with WordPress 2.2.x and 2.3.x.
713 +
714 +* WORDPRESS 2.2 AND 2.3 COMPATIBILITY: FeedWordPress should now be
715 + compatible with WordPress version 2.2 and the upcoming WordPress
716 + version 2.3. In particular, it has been tested extensively against
717 + WordPress 2.2.3 and WordPress 2.3 Release Candidate 1.
718 +
719 +* AUTOMATIC UPDATES WITHOUT CRON: FeedWordPress now allows you to
720 + automatically schedule checks for new posts without using external task
721 + scheduling tools such as cron. In order to enable automatic updates, go
722 + to **Syndication --> Options** and set "Check for new posts" to
723 + "automatically." For details, see "Automatic Feed Updates" in
724 + README.text.
725 +
726 + An important side-effect of the changes to the update system is that if
727 + you were previously using the cron job and the `update-feeds.php` script
728 + to schedule updates, you need to change your cron set-up. The old
729 + `update-feeds.php` script no longer exists. Instead, if you wish to use
730 + a cron job to guarantee updates on a particular schedule, you should
731 + have the cron job fetch the front page of your blog (for example, by
732 + using `curl http://www.zyx.com/blog/ > /dev/null`) instead of activating
733 + the `update-feeds.php` script. If automatic updates have been enabled,
734 + fetching the front page will automatically trigger the update process.
735 +
736 +* INTERFACE REORGANIZATION: All FeedWordPress functions are now located
737 + under a top-level "Syndication" menu in the WordPress Dashboard. To
738 + manage the list of syndicated sites, manually check for new posts on
739 + one or more feeds, or syndicate a new site, you should use the main page
740 + under **Syndication**. To change global settings for FeedWordPress,
741 + you should use **Syndication --> Options**.
742 +
743 +* FILE STRUCTURE REORGANIZATION: Due to a combination of changing styles
744 + for FeedWordPress plugins and lingering bugs in the FeedWordPress admin
745 + menu code, the code for FeedWordPress is now contained in two different
746 + PHP files, which should be installed together in a subdirectory of your
747 + plugins directory named `feedwordpress`. (See README.text for
748 + installation and upgrade instructions relating to the change.)
749 +
750 +* MULTIPLE CATEGORIES SETTING: Some feeds use non-standard methods to
751 + indicate multiple categories within a single category element. (The most
752 + popular site to do this is del.icio.us, which separates tags with a
753 + space.) FeedWordPress now allows you to set an optional setting, for any
754 + feed which does this, indicating the character or characters used to
755 + divide multiple categories, using a Perl-compatible regular expression.
756 + (In the case of del.icio.us feeds, FeedWordPress will automatically use
757 + \s for the pattern without your having to do any further configuration.)
758 + To turn this setting on, simply use the "Edit" link for the feed that
759 + you want to turn it on for.
760 +
761 +* REGULAR EXPRESSION BUG FIXED: Eliminated a minor bug in the regular
762 + expressions for e-mail addresses (used in parsing RSS `author`
763 + elements), which could produce unsightly error messages for some users
764 + parsing RSS 2.0 feeds.
765 +
766 +* DATE / UPDATE BUG FIXED: A bug in date handling was eliminated that may
767 + have caused problems if any of (1) WordPress, or (2) PHP, or (3) your
768 + web server, or (4) your MySQL server, has been set to use a different
769 + time zone from the one that any of the others is set to use. If
770 + FeedWordPress has not been properly updating updated posts, or has been
771 + updating posts when there shouldn't be any changes for the update, this
772 + release may solve that problem.
773 +
774 +* GOOGLE READER BUGS FIXED: A couple of bugs that made it difficult for
775 + FeedWordPress to interact with Google Reader public feeds have been
776 + fixed. Firstly, if you encountered an error message reading "There was a
777 + problem adding the newsfeed. [SQL: ]" when you tried to add the feed,
778 + the cause of this error has been fixed. Secondly, if you succeeded in
779 + getting FeedWordPress to check a Google Reader feed, only to find that
780 + the title of posts had junk squashed on to the end of them, that bug
781 + has been fixed too. To fix this bug, you must install the newest version
782 + of the optional MagpieRSS upgrade.
783 +
784 +* FILTER PARAMETERS: Due to an old, old bug in WordPress 1.5.0 (which was
785 + what was available back when I first wrote the filter interface),
786 + FeedWordPress has traditionally only passed one parameter to
787 + syndicated_item and syndicated_post filters functions -- an array
788 + containing either the Magpie representation of a syndicated item from
789 + the feed, or the database representation of a post about to be inserted
790 + into the WordPress database. If you needed information about the feed
791 + that the item came from, this was accessible only through a pair of
792 + global variables, $fwp_channel and $fwp_feedmeta.
793 +
794 + Since it's been a pretty long time since WordPress 1.5.0 was in
795 + widespread usage, I have gone ahead and added an optional second
796 + parameter to the invocation of the syndicated_item and syndicated_post
797 + filters. If you have written a filter for FeedWordPress that uses either
798 + of these hooks, you can now register that filter to accept 2 parameters.
799 + If you do so, the second parameter will be a SyndicatedPost object,
800 + which, among other things, allows you to access information about the
801 + feed from which an item is syndicated using the $post->feed and the
802 + $post->feedmeta elements (where $post is the name of the second
803 + parameter).
804 +
805 + NOTE THAT THE OLD GLOBAL VARIABLES ARE STILL AVAILABLE, for the time
806 + being at least, so existing filters will not break with the upgrade.
807 + They should be considered deprecated, however, and may be eliminated in
808 + the future.
809 +
810 +* FILTER CHANGE / BUGFIX: the array that is passed as the first argument
811 + syndicated_post filters no longer is no longer backslash-escaped for
812 + MySQL when filters are called. This was originally a bug, or an
813 + oversight; the contents of the array should only be escaped for the
814 + database *after* they have gone through all filters. IF YOU HAVE WRITTEN
815 + ANY syndicated_post FILTERS THAT PRESUME THE OLD BEHAVIOR OF PASSING IN
816 + STRINGS THAT ARE ALREADY BACKSLASH-ESCAPED, UPDATE YOUR FILTERS
817 + ACCORDINGLY.
818 +
819 +* OTHER MINOR BUGFIXES AND INTERNAL CHANGES: The internal architecture of
820 + FeedWordPress has been significantly changed to make the code more
821 + modular and clean; hopefully this should help reduce the number of
822 + compatibility updates that are needed, and make them easier and quicker
823 + when they are needed.
824 +
825 +Changes from 0.98 to 0.981
826 +--------------------------
827 +Version 0.981 is a narrowly targeted bugfix and compatibility release, whose
828 +main purpose is to resolve a major outstanding problem: the incompatibility
829 +between version 0.98 of WordPress and the recently released WordPress 2.1.
830 +
831 +* WORDPRESS 2.1 COMPATIBILITY: FeedWordPress is now compatible with
832 + WordPress 2.1, as well as retaining its existing support for WordPress
833 + 2.0 and 1.5. Incompatibilities that resulted in database warnings, fatal
834 + errors, and which prevented FeedWordPress from syndicating new posts,
835 + have been eliminated.
836 +
837 +* RSS-FUNCTIONS.PHP RENAMED TO RSS.PHP: if you use the upgraded MagpieRSS
838 + replacement that's included with FeedWordPress, be sure to note that
839 + there are now *two* files to upload from the `OPTIONAL/wp-includes`
840 + subdirectory in order to carry out the upgrade: rss-functions.php and
841 + rss.php. **It is necessary to upload both files**, due to a change in
842 + the file naming scheme in WordPress 2.1, and it is necessary to do so
843 + whether you are using WordPress 2.1 or not. If you only upload the
844 + `rss-functions.php` file as in previous installations you will not have
845 + a working copy of MagpieRSS; the rss.php file contains the actual code.
846 +
847 +* DATE BUG AFFECTING SOME PHP INSTALLATIONS RESOLVED: due to a subtle bug
848 + in parse_w3cdtf(), some installations of PHP encountered problems with
849 + FeedWordPress's attempt to date posts, which would cause some new posts
850 + on Atom feeds to be dated as if they had apppeared in 1969 or 1970
851 + (thus, effectively, never appearing on front page at all). This bug in
852 + the date handling should now be fixed.
853 +
854 +* PHP <?=...?> SHORT FORM ELIMINATED: some installations of PHP do not
855 + allow the <?=...?> short form for printing PHP values, which was used
856 + extensively in the FeedWordPress interface code. Since this could cause
857 + fatal errors for users with the wrong installation of PHP, the short
858 + form has been replaced with full PHP echo statements, and is no longer
859 + used in FeedWordPress.
860 +
861 +* BETTER USER INTERFACE INTEGRATION WITH WORDPRESS 2.x: Some minor changes
862 + have been made to help the FeedWordPress interface pages blend in better
863 + with the user interface when running under WordPress 2.x.
864 +
865 +* GLOBAL CATEGORIES BUG RESOLVED: a bug that prevented some users from
866 + setting one or more categories to apply to syndicated posts from all
867 + feeds (using the checkbox interface under Options --> Syndication) has
868 + been resolved.
869 +
870 +Changes from 0.97 to 0.98
871 +--------------------------
872 +
873 +* WORDPRESS 2.0 COMPATIBILITY: This is a narrowly-targeted release to
874 + solve a major outstanding problem. FeedWordPress is now compatible with
875 + both WordPress 1.5 and WordPress 2.0. Incompatibilities that caused
876 + fatal SQL errors, and a more subtle bug with off-kilter counts of posts
877 + under a given category, have been resolved. FeedWordPress tests for
878 + database schema using the global $wp_db_version variable (if null, then
879 + we presume that we're dealing with WordPress 1.5).
880 +
881 + NOTE: I have **not** fully tested FeedWordPress with WordPress 2.0.
882 + Further testing may reveal more bugs. However, you should now be able
883 + to get at least basic FeedWordPress functionality up and running.
884 +
885 +* AUTHOR MATCHING: FeedWordPress tests several fields to see if it can
886 + identify the author of the post as a user already in the WordPress user
887 + database. In previous versions, it tested the user login, the nickname,
888 + and tested for "aliases" listed in the Profile (see documentation). FWP
889 + now also matches authors on the basis of e-mail address (*if* an e-mail
890 + address is present). This is particularly helpful for formats such as
891 + RSS 2.0, in which authors are primarily identified by e-mail addresses.
892 +
893 +Changes from 0.96 to 0.97
894 +-------------------------
895 +
896 +* INSTALLATION PROCEDURE: Some of the changes between 0.96 and 0.97
897 + require upgrades to the meta-data stored by FeedWordPress to work
898 + properly. Thus, if you are upgrading from 0.96 or earlier to 0.97, most
899 + FeedWordPress operations (including updates and template functions)
900 + WILL BE DISABLED until you run the upgrade procedure. Fortunately,
901 + running the upgrade procedure is easy: just go to either Options -->
902 + Syndication or Links --> Syndicated in the WordPress Dashboard and press
903 + the button.
904 +
905 +* FEED FORMAT SUPPORT: Support has been added for the Atom 1.0 IETF
906 + standard. Several other elements are also newly supported
907 + (dcterms:created, dcterms:issued, dcterms:modified, dc:identifier,
908 + proper support for the RSS 2.0 guid element, the RSS 2.0 author element,
909 + the use of Atom author or Dublin Core dc:creator constructs at the feed
910 + level to identify the author of individual items, etc.)
911 +
912 + N.B.: full support of several Atom 1.0 features, such as categories
913 + and enclosures, requires you to install the optional rss-functions.php
914 + upgrade in your wp-includes directory.
915 +
916 +* BUG FIX: Running `update-feeds.php` from command line or crontab
917 + returned "I don't syndicate..." errors. It turns out that WordPress
918 + sometimes tramples on the internal PHP superglobals that I depended on
919 + to determine whether or not the script was being invoked from the
920 + command line. This has been fixed (the variables are now checked
921 + *before* WordPress can trample them). Note that `update-feeds.php` has
922 + been thoroughly overhauled anyway; see below for details.
923 +
924 +* BUG FIX: Duplicate categories or author names. Fixed two bugs that could
925 + create duplicate author and/or category names when the name contained
926 + either (a) certain international characters (causing a mismatch between
927 + MySQL and PHP's handling of lowercasing text), or (b) characters that
928 + have a special meaning in regular expressions (causing MySQL errors when
929 + looking for the author or category due to regexp syntax errors). These
930 + should now be fixed thanks to careful escaping of names that go into
931 + regular expressions and careful matching of lowercasing functions
932 + (comparing results from PHP only to other results from PHP, and results
933 + from MySQL only to other results from MySQL).
934 +
935 +* BUG FIX: Items dated December 31, 1969 should appear less often. The
936 + function for parsing W3C date-time format dates that ships with
937 + MagpieRSS can only correctly parse fully-specified dates with a
938 + fully-specified time, but valid W3C date-time format dates may omit the
939 + time, the day of the month, or even the month. Some feeds in the wild
940 + date their items with coarse-grained dates, so the optional
941 + `rss-functions.php` upgrade now includes a more flexible parse_w3cdtf()
942 + function that will work with both coarse-grained and fully-specified
943 + dates. (If parts of the date or the time are omitted, they are filled in
944 + with values based on the current time, so '2005-09-10' will be dated to
945 + the current time on that day; '2004' will be dated to this day and time
946 + one year ago.
947 +
948 + N.B.: This fix is only available in the optional `rss-functions.php`
949 + upgrade.
950 +
951 +* BUG FIX: Evil use of HTTP GET has been undone. The WordPress interface
952 + is riddled with inappropriate (non-idempotent) uses of HTTP GET queries
953 + (ordinary links that make the server do something with significant
954 + side-effects, such as deleting a post or a link from the database).
955 + FeedWordPress did some of this too, especially in places where it aped
956 + the WordPress interface (e.g. the "Delete" links in Links -->
957 + Syndicated). That's bad business, though. I've changed the interface so
958 + that all the examples of improper side-effects that I can find now
959 + require an HTTP POST to take effect. I think I got pretty much
960 + everything; if there's anything that I missed, let me know.

963 +
964 +* BUG FIX: Categories applied by `cats` setting should no longer prevent
965 + category-based filtering from working. In FeedWordPress, you can (1)
966 + apply certain categories to all syndicated posts, or all posts from
967 + a particular feed; and (2) filter out all posts that don't match one
968 + of the categories that are already in the WordPress database (allowing
969 + for simple category-based filtering; just load up WordPress with the
970 + categories you want to accept, and then tell FeedWordPress not to create
971 + new ones). However, the way that (1) and (2) were implemented meant that
972 + you couldn't effectively use them together; once you applied a known
973 + category to all syndicated posts from a particular feed, it meant that
974 + they'd have at least one familiar category (the category or categories
975 + you were applying), and that would get all posts past the filter no
976 + matter what categories they were originally from.
977 +
978 + Well, no longer. You can still apply categories to all syndicated posts
979 + (using either Syndication --> Options, or the feed-level settings under
980 + Links --> Syndicated). But these categories are not applied to the post
981 + until *after* it has already passed by the "familiar categories" filter.
982 + So now, if you want, you can do category filtering and *then* apply as
983 + many categories as you please to all and only posts that pass the filter.
984 +
985 +* BUG FIX: Other minor typos and HTML gaffes were fixed along the way.
986 +
987 +* PERFORMANCE: get_feed_meta() no longer hits the database for information
988 + on every call; it now caches link data in memory, so FeedWordPress only
989 + goes to the database once for each syndicated link. This may
990 + substantially improve performance if your database server resources
991 + are tight and your templates make a lot of use of custom settings from
992 + get_feed_meta().
993 +
994 +* API CHANGE: Link ID numbers, rather than RSS URIs, are now used to
995 + identify the feed from which a post is syndicated when you use template
996 + functions such as get_feed_meta(). The practical upshot of this is you
997 + can switch feeds, or change the feed address for a particular syndicated
998 + site, without breaking your templates for all the posts that were
999 + syndicated from the earlier URI.
1000 +
1001 +* API CHANGE: if you have plugins or templates that make use of the
1002 + get_feed_meta() function or the $fwp_feedmeta global, note that the
1003 + data formerly located under the `uri` and `name` fields is now located
1004 + under the `link/uri` field and the `link/name` field, respectively. Note
1005 + also that you can access the link ID number for any given feed under the
1006 + global $fwp_feedmeta['link/id'] (in plugins) or
1007 + get_feed_meta('link/id') (in a template in post contexts).
1008 +
1009 +* FEATURE: the settings for individual feeds can now be edited using a
1010 + humane interface (where formerly you had to tweak key-value pairs in the
1011 + Link Notes section). To edit settings for a feed, pick the feed that you
1012 + want under Links --> Syndicated and click the Edit link.
1013 +
1014 +* FEATURE: The "Unsubscribe" button (formerly "Delete") in Links -->
1015 + Syndicated now offers three options for unsubscribing from a feed: (1)
1016 + turning off the subscription without deleting the feed data or affecting
1017 + posts that were syndicated from the feed (this works by setting the Link
1018 + for the feed as "invisible"); (2) deleting the feed data and all of the
1019 + posts that were syndicated from the feed; or (3) deleting the feed data
1020 + and *keeping* the posts that were syndicated from the feed
1021 + setting the Link to "Invisible" (meaning that it will not be displayed
1022 + in lists of the site links on the front page, and it won't be checked
1023 + for updates; (2) deleting the Link and all of the posts that were
1024 + syndicated from its feed; or (3) deleting the feed data but keeping the
1025 + posts that were syndicated (which will henceforward be treated as if
1026 + they were local rather than syndicated posts). (Note that (1) is usually
1027 + the best option for aggregator sites, unless you want to clean up the
1028 + results of an error or a test.)
1029 +
1030 +* FEATURE / BUG FIX: If you have been receiving mysterious "I don't
1031 + syndicate...", or "(local) HTTP status code was not 200", or "(local)
1032 + transport error - could not open socket", or "parse error - not well
1033 + formed" errors, then this update may solve your problems, and if it does
1034 + *not* solve them, it will at least make the reasons for the problems
1035 + easier to understand. That's because I've overhauled the way that
1036 + FeedWordPress goes about updating feeds.
1037 +
1038 + If you use the command-line PHP scripting method to run scheduled
1039 + updates, then not much should change for you, except for fewer
1040 + mysterious errors. If you have done updates by sending periodic HTTP
1041 + requests to <http://your-blog.com/path/wp-content/update-feeds.php>,
1042 + then the details have changed somewhat; mostly in such a way as to make
1043 + things easier on you. See the README file or online documentation on
1044 + Staying Current for the details.
1045 +
1046 +* FEATURE: FeedWordPress now features a more sophisticated system for
1047 + timed updates. Instead of polling *every* subscribed feed for updates
1048 + *each* time `update-feeds.php` is run, FeedWordPress now keeps track of
1049 + the last time it polled each feed, and only polls them again after a
1050 + certain period of time has passed. The amount of time is normally set
1051 + randomly for each feed, in a period between 30 minutes and 2 hours (so
1052 + 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
1053 + directly by the feed, which brings us to ...
1054 +
1055 +* FEATURE: FeedWordPress now respects the settings in the `ttl` and
1056 + Syndication Module RSS elements. Feeds with these elements set will not
1057 + be polled any more frequently than they indicate with these feeds unless
1058 + the user manually forces FeedWordPress to poll the feed (see Links -->
1059 + Syndicated --> Edit settings).
1060 +
4 1061 Changes from 0.95 to 0.96
