17 FeedWordPress is an Atom/RSS aggregator for WordPress. It syndicates content
18 from feeds that you choose into your WordPress weblog; the content it syndicates
19 appears as a series of special posts in your WordPress posts database. If you
20 syndicate several feeds then you can use WordPress's posts database and
21 templating engine as the back-end of an aggregation ("planet") website. It was
22 developed, originally, because I needed a more flexible replacement for
23 [Planet][] to use at [Feminist Blogs][].

27
28 FeedWordPress is designed with flexibility, ease of use, and ease of
29 configuration in mind. You'll need a working installation of WordPress or
30 WordPress MU (version [3.0] or later), and also FTP or SFTP access to your web
31 host. The ability to create cron jobs on your web host is helpful but not
32 required. You *don't* need to tweak any plain-text configuration files and you
33 *don't* need shell access to your web host to make it work. (Although, I should
34 point out, web hosts that *don't* offer shell access are *bad web hosts*.)

40 == Installation ==
41
42 To use FeedWordPress, you will need:
43
44 * an installed and configured copy of [WordPress][] or [WordPress MU][]
45 (version 3.0 or later).
46
47 * FTP, SFTP or shell access to your web host
48
49 = New Installations =
50
51 1. Download the FeedWordPress installation package and extract the files on
52 your computer.
53
54 2. Create a new directory named `feedwordpress` in the `wp-content/plugins`
55 directory of your WordPress installation. Use an FTP or SFTP client to
56 upload the contents of your FeedWordPress archive to the new directory
57 that you just created on your web host.
58
59 3. Log in to the WordPress Dashboard and activate the FeedWordPress plugin.
60
61 4. Once the plugin is activated, a new **Syndication** section should
62 appear in your WordPress admin menu. Click here to add new syndicated
63 feeds, set up configuration options, and determine how FeedWordPress
64 will check for updates. For help, see the [FeedWordPress Quick Start][]
65 page.

96
97 = 2011.0721 =
98
99 * BUGFIX: SERIOUS BUG CAUSING RARE UNEXPECTED DELETION OF PAGES AND OTHER
100 CONTENT. A bug in the guid-checking code for some rare kinds of guids could
101 cause content in the wp_posts table to seemingly disappear at random after
102 FeedWordPress updates.This most frequently but not exclusively affected
103 static pages. What actually happened is that in these rare cases the
104 existing static page was mistaken for an older version of the new incoming
105 syndicated post, which was then stored as a new revision of the original
106 page. The bug that caused these mistaken identities has been fixed.
107
108 * BUGFIX: UNWANTED AUTOMATIC PAGE-LOAD-BASED UPDATES NO LONGER A NUISANCE.
109 Some users encountered a bug in which FeedWordPress would adopt an automatic
110 page-load-based update method, even if they had requested that it not do
111 so, and that it use a manual or cron job update method instead. The bug
112 causing this has been fixed, and page-load-based updates should no longer
113 trigger unless explicitly turned on.
114
115 * WP 3.2 USER INTERFACE COMPATIBILITY: POST TAGS BOX NOW WORKS AGAIN. The
116 release of WordPress 3.2 caused a breakage in the tags box which prevented
117 you from adding or removing tags under Syndication --> Categories & Tags.
118 (The breakage was the result of an incompatibility introduced by the new
119 release of jQuery.) This breakage has now been fixed, and the tags box
120 should work correctly again.
121
122 * FEED UPDATE SCHEDULING IMPROVEMENTS: UI. The Syndicated Sources table now
123 provides considerably more data to understand update scheduling, when
124 specific scheduling decisions are made because of, e.g., requests from the
125 feed producer.
126
127 * FEED UPDATE SCHEDULING IMPROVEMENTS: ENFORCEABLE "MINIMUM INTERVAL" SETTIN
128 TO SPACE OUT UPDATES. Some feeds request specific update schedules, using
129 standard elements such as sy:updateFrequency and rss:ttl. Normally,
130 FeedWordPress respects any scheduling requests that a feed makes -- if it
131 requests a longer gap between polls than what FWP would normally adopt, then
132 FWP slows down to meet the request. If it indicates a shorter gap than what
133 FWP would normally adopt, FWP speeds up and checks that feed for updates
134 more often than it normally would. Now, there should not be any way for user
135 settings to override an explicit slow-down request from the feed producer --
136 if producers indicate a particular update schedule, then polling the feed
137 more frequently than they request is considered abusive behavior. But
138 there's no reason why users should not be able -- if they so desire -- to
139 override speed-up requests, and poll a feed *less* frequently than the
140 indicated update schedule, if the FWP user wants to space update checkins
141 over a longer interval of time. Before, they could not do this: FWP always
142 sped up to meet the indicated update schedule. Now, they can do this, by
143 using the new "Minimum Interval" setting in Syndication --> Feeds &
144 Updates..
145
146 = 2011.0706 =
147
148 * WP 3.2 COMPATIBILITY: ELIMINATES FATAL ERROR "Call to undefined method
149 WP_SimplePie_File::WP_SimplePie_File() in
150 [...]/wp-content/plugins/feedwordpress/feedwordpress.php on line 1841." The
151 latest release of WordPress, version 3.2, has shifted the minimum
152 requirements up to PHP 5.2, and in line with the shift to PHP5 they have
153 rewritten a number of code segments that made use of now-obsolete PHP4
154 idioms. Unfortunately, this caused a fatal error whenever FeedWordPress
155 attempted to make use of the cache, since FWP's caching plugin was written
156 to match the older idiom. FeedWordPress has been updated to follow the new,
157 PHP5 idiom when possible, thus eliminating the fatal error.
158
159 * PERFORMANCE: The handling of queries to determine whether posts had been
160 previously syndicated produced some very slow queries (usually, but not
161 always, involving a scan over the MD5(post_guid) column of the table). The
162 code that prepares MySQL queries for previously-syndicated checks has been
163 revised to eliminate the MD5(post_guid) scan entirely, and to significantly
164 improve performance by eliminating other unnecessary clauses.
165
166 * BUGFIX: NO LONGER DESTROYS STICKY POSTS. Previous versions could destroy
167 (or, more precisely, replace the content of) sticky posts due to some
168 queries mashed together in unexpected ways by WordPress. Version 2011.0706
169 accounts for and eliminates the problem; your sticky posts should be safe
170 once again.
171
172 * BUGFIX: GUIDS CONTAINING MYSQL-ESCAPED CHARACTERS NO LONGER CAUSE DUPLICATE
173 POSTS TO APPEAR. One remaining source of duplicate post issues in 2011.0602
174 was guids that contained characters that needed to be escaped for MySQL,
175 such as single quotes and double quotes. The work-around for handling
176 filtered URIs has now been corrected to ensure that these do not cause
177 duplicate posts.
178
179 = 2011.0602 =
180
181 * WP 3.1.3 COMPAT / BUGFIX: WHITESPACE IN GUIDS NO LONGER PRODUCES DUPLICATE
182 POSTS. The work-around for handling filtered URIs in guid elements has now
183 been extended to handle URIs that were filtered because of leading or
184 trailing whitespace, in addition to URIs that were filtered because of
185 unapproved schemes.
186
187 * WP 3.1.3 COMPAT / BUGFIX: RELATIVE URLS IN GUIDS NO LONGER PRODUCE DUPLICATE
188 POSTS. The work-around for handling filtered URIs in guid elements has now
189 been extended to handle URIs that were altered without being filtered out
190 entirely (most commonly because a scheme was added to a relative URL).
191
192 * BUGFIX: UPDATES TO POST NO LONGER CAUSE DUPLICATE DRAFT VERSION TO APPEAR.
193 Under certain conditions in 2011.0531, an update to an existing post would
194 not be properly applied to the post itself, but rather would appear as a
195 duplicate post with Draft status. This bug has been eliminated, and updates
196 will now be properly inserted as revisions to the existing post.
197
198 = 2011.0531 =
199
200 * WORDPRESS 3.1.3 COMPATIBILITY: DUPLICATE POSTS ISSUE FIXED. Due to
201 internal changes in the way that WordPress handles post guids in the
202 most recent release (3.1.3), many users experienced problems with many
203 duplicate posts appearing in rapid succession. (Specifically, this would
204 happen with any posts using tag: URL guids -- such as all the posts
205 coming from Blogger feeds or feeds from other Google services.) This
206 compatibility release of FeedWordPress eliminates the issue by working
207 around the new restrictions on tag: URLs.
208
209 * NEW AND IMPROVED DIAGNOSTICS: Syndication --> Diagnostics now contains some
210 new diagnostics settings useful for debugging problems with duplicate posts
211 (allowing you to easily view the guid of posts in the WordPress posts
212 database and allowing you to track the SQL used to check for existing
213 versions of a syndicated post).
214
215 = 2011.0512 =
216
217 * DIAGNOSTICS IMPROVEMENTS; "THERE MAY BE A BUG IN FEEDWORDPRESS" CRITICAL
218 ERROR NOTICES ELIMINATED: This version includes some major improvements
219 to the Syndication --> Diagnostics section, which should aid in
220 troubleshooting difficulties with items failing to be imported, posts
221 failing to be properly inserted into the database, or updates failing to
222 be recorded. If you have been encountering critical error / bug notices
223 with a white screen and the message "THERE MAY BE A BUG IN
224 FEEDWORDPRESS," followed by an extraordinarily long dump of mostly
225 incomprehensible diagnostic information, you'll be happy to know that
226 the condition causing these notices has been eliminated. In the few
227 cases where errors may still crop up with database insertions,
228 FeedWordPress will now produce a significantly more manageable and more
229 useful diagnostic message.
230
231 * BUGFIX: NEW POSTS FAILING TO APPEAR IN A CLEANLY-INSTALLED FEEDWORDPRESS
232 SYSTEM. If you encountered a recurring problem with FeedWordPress
233 failing to import new posts, after a clean install of FeedWordPress
234 (i.e., not an upgrade from a previous version), this problem may have
235 been the result of a bug with author-handling which has now been fixed
236 in the 2011.0512 release. (If the problem does *not* go away with the
237 upgrade, this version also includes significant improvements to the
238 Diagnostics system, which will help track down what *is* causing it
239 in your particular case.)
240
241 * PERFORMANCE: New handling of update hashes allows FeedWordPress to avoid
242 a certain kind of infinite loop, caused when two more more different
243 syndicated feeds each carried a version of the same item (for example,
244 because it appeared on two different aggregator feeds that you're
245 syndicating). In previous versions, when this kind of loop cropped up,
246 syndicated posts could pile up an indefinitely large number of revisions
247 -- each revision alternating between the version from each of the two
248 feeds where it appeared -- which would, over time, dramatically inflate
249 the size of the database, and kill the performance of queries on the
250 post table. This issue has been resolved: revisions of the post that
251 have been syndicated once will not be re-syndicated over and over again.
252
253 * AUTHOR LISTS: Lists of authors presented on the Author settings pages
254 should now be easier to scan through, with author names arranged in
255 alphabetical order.
256
257 * FEED ITEM DATE PARSING: More tweaks to make date-time handling more
258 resilient when feeds provide broken or weird values for the timestamps
259 on syndicated items. FWP will now attempt to work around unparseable
260 timezone values.
261
262 * AUTHOR MATCHING: Now attempts to match author names against the WP login
263 name in addition to display_name; when creating user record, also fills
264 in some best-guess values for nickname, firstname and lastname. Also
265 properly picks up Atom 1.0 author/uri data from feed.
266
267 * COMPATIBILITY: FeedWordPress has been successfully tested for
268 compatibility with recent releases of WordPress, up to version 3.1.2.
269
270 = 2011.0211 =
271
272 * BUGFIX: DUPLICATE POSTS WHEN GUIDS ARE TOO LONG: When feeds included
273 exceptionally long GUIDs, FeedWordPress could occasionally get into
274 a situation where posts with the long GUIDs would be duplicated over
275 and over again with each update (because FWP failed to store the full
276 GUID, due to length constraints in the relevant database tables).
277 Without the full GUID, FWP would not know that the post had already
278 been syndicated once. This bug has been fixed, and should no longer
279 produce duplicate posts.
280
281 * HTTP TIMEOUT SETTING: If you are frequently running into timeout
282 problems with one or more of the feeds you syndicate, FWP now allows you
283 to adjust the timeout for HTTP requests using a global or feed-by-feed
284 setting.
285
286 * HTTP GET PARAMETERS: You can now temporarily or permanently add HTTP
287 GET parameters to a subscription using an interface in Syndication -->
288 Feeds & Updates. This is especially helpful for making quick, short-term
289 changes to a subscription (for example, to pull in all the previous
290 items from a web service, before settling down to pulling in only newly
291 updated items).
292
293 * DIAGNOSTICS SYSTEM: Added several new diagnostics which are useful in
294 troubleshooting, and established a framework for add-on modules to hook
295 in with their own diagnostic messages.
296
297 * UI: Adjusted some internal coding, which should allow for settings
298 pages and add-ons to properly display multiple category pickers on a
299 single settings page.
300
301 * PHP4 COMPATIBILITY TWEAKS: This version makes some tweaks to the handling
302 of object references which should improve compatibility with older
303 versions of PHP. (Although, I should note, web hosts that still force
304 you to run under PHP 4 -- in 2011! -- are *bad web hosts*.)
305
306 * IMPROVED PERFORMANCE: This version eliminates a *major* performance drag
307 that shows up on sites with large numbers of users (due to some poor
308 decisions about where to place a user query, which caused the user table
309 to be scanned frequently when it did not need to be). If you experienced
310 serious problems with CPU load or slow database performance under
311 2010.0905, which kicked in immediately when FWP was loaded and tended
312 to disappear immediately if FWP was de-activated, it is likely that
313 upgrading away from 2010.0905 to the most recent version will resolve
314 your problem.
315
316
317 = 2010.0905 =
318
319 * BUGFIX: CATEGORIES AND TAGS CORRECTLY ASSIGNED IN AUTOMATIC UPDATES.
320 Version 2010.0903 switched over to a new way of assigning categories and
321 tags as part of its support for handling custom taxonomies.
322 Unfortunately, the method that it uses is subjected to some checks of
323 the current user's capabilities, which creates problems for posts that
324 are being inserted into the WordPress database when there *is* no
325 current user logged in (as, for example, when an update is being carried
326 out from a cron job or automatic update). The result was that posts
327 from cron jobs and automatic updates ended up with no Categories and no
328 Tags being assigned. This bug has now been fixed: in 2010.0905, Tags and
329 Categories should be correctly assigned to all posts, regardless of
330 whether they were added from manual updates, cron jobs, or automatic
331 updates.
332
333 = 2010.0903 =
334
335 * WORDPRESS 3 REQUIRED: Please note that this release of FeedWordPress
336 *requires* WordPress 3.0 or later. If you are currently using a 2.x
337 branch of WordPress, you will need to upgrade to WordPress 3 before you
338 can successfully upgrade FeedWordPress.
339
340 * BUGFIX: NO MORE DISAPPEARING "SYNDICATED SOURCES" PANEL; INTERNET
341 EXPLORER UI GLITCH APPARENTLY FIXED: Several users independently
342 reported a problem with FWP 2010.0623 and various versions of IE. A
343 problem with the HTML markup caused IE (but not Firefox or
344 Chrome) to completely hide the Syndicated Sources administration panel
345 (the main list of currently-syndicated sources, and the main location
346 for adding new sources, under the Syndication menu item) when a user
347 added their first syndicated feed. Maddeningly, the glitch seemed to
348 affect some IE users and not others: I was never able to reproduce the
349 problem for myself on my own machines. However, the markup of Syndicated
350 Sources has undergone significant changes and corrections since
351 2010.0623, and two independent sources who had been having this problem
352 confirm that they no longer encounter it with the updated version. For
353 the time being, I am going to declare this bug squashed.
354
355 * BUGFIX: MORE PROTECTION AGAINST FATAL ERRORS FROM PLUGGABLE VERSIONS OF
356 SimplePie: FeedWordPress now takes some precautions that should help to
357 better avoid conflicts for users who have installed pluggable versions
358 of SimplePie for another plugin or theme. (You may not know that you have
359 done this; but if you've been encountering fatal errors indicating that
360 you cannot redeclare class SimplePie, or something along those lines,
361 there is now a better chance that those fatal errors will be eliminated.
362
363 * PERFORMANCE: SIGNIFICANTLY REDUCED MEMORY CONSUMPTION FOR LARGE UPDATES:
364 FeedWordPress is still a memory-hungry little module, especially when
365 you are dealing with very large feeds. However, users should notice a
366 significant reduction in memory overloads, especially if they update a
367 large number of feeds at once.
368
369 * USER INTERFACE IMPROVEMENTS: Nothing is radically different, but there's
370 been a fair amount of extra spit and polish added, including a convenient
371 new Dashboard widget that may save you a trip to the Syndication menu,
372 a lot of effort to make the relationship between global and feed-by-feed
373 settings more obvious to the user and more easily controllable, to make
374 navigation between settings pages easier, to sand off a few rough edges,
375 and to make other improvements on the margins. I hope you'll like how
376 it looks.
377
378 * ADDING MULTIPLE FEEDS: FeedWordPress now provides a convenient mode for
379 adding multiple feeds at once, using either a copy-and-pasted list, or
380 else an OPML file. Go to Syndication --> Syndicated Sources and check
381 out the two new buttons underneath the New Source input box. When you
382 have to add a number of feeds at once, this can save you considerable
383 time and trouble.
384
385 * IMPROVED HANDLING OF AUTHORS WITH DUPLICATE E-MAIL ADDRESS AND AUTHORS
386 WITH NAMES WRITTEN IN FOREIGN SCRIPTS: WordPress 3 is increasingly picky
387 about what it will accept for new author accounts, and some of the
388 conditions it imposes can cause error conditions that prevent posts from
389 being properly syndicated, or properly attributed, if authors happen to
390 have identical e-mail addresses, or if users are given usernames that are
391 written in non-Western scripts. FeedWordPress now handles these much
392 better, and systematically works to avoid clashes between syndicated
393 authors' account names or in their e-mail addresses, which should result
394 in significantly better results in mapping author names to WordPress
395 user accounts.
396
397 * MAPPING CATEGORIES ON SYNDICATED POSTS TO TAGS NOW BETTER SUPPORTED:
398 In previous versions, the only way for the Categories provided by a
399 syndicated feed to be mapped into Post Tags was to instruct FWP to
400 create new tags, rather than new categories, for unfamiliar categories
401 from the feed. This works fine if you want tags to be the default; but
402 if you want only a *specific* set of tags, there was no way to get them
403 without getting most or all other categories imported as tags. You can
404 now do this by creating a tag (under Posts ==> Post Tags) before
405 importing the post; when the syndicated category matches a pre-existing
406 tag, the incoming post will be tagged with that tag, without creating
407 a local Post Category.
408
409 * REL-TAG MICROFORMAT SUPPORT FOR INLINE TAGS: Syndicated posts that
410 contain inline tags, marked up using the Rel-Tag microformat
411 <http://microformats.org/wiki/rel-tag>, are now tagged with the tags
412 provided by Rel-Tag format links.
413
414 * MUCH GREATER CONTROL OVER CATEGORY AND TAG MAPPING: This is partly the
415 result of building in support for a potentially endless set of custom
416 taxonomies (see below), but in general there has been a great deal of
417 effort towards giving you more control over how categories and tags
418 provided by the feed are mapped into terms on the local blog. In
419 particular, you can now force FeedWordPress to create only categories
420 from categories and tags provided by the feed; or to create only tags;
421 or to search both categories and tags for a match; or you can simply
422 force it to drop all of the categories provided by the feed and use
423 only categories or tags that you explicitly provide. In addition, you
424 can now also choose whether to override global categories settings with
425 a local, feed-specific setting; or whether to *add together* *both* the
426 global categories and the local feed-specific categories -- depending
427 on whatever your use-case may demand.
428
429 * CUSTOM POST TYPES AND TAXONOMY SUPPORTS: This is mainly for the
430 super-geeky, but if you use other plugins or themes that make
431 significant use of WordPress's support for custom post types and custom
432 taxonomies, you may be pleased to find that FeedWordPress now allows you
433 to feed incoming posts into any custom feed type that you wish, and to
434 map categories and tags from the feed to custom taxonomies as well as
435 to the standard Category and Tag taxonomies.
436
437 * STORING NAMESPACED CUSTOM FEED ELEMENTS IN POST CUSTOM FIELDS: If you
438 would like to use FeedWordPress's support for storing custom meta-data
439 from feed elements in the custom fields for a post (for example, to
440 store geolocation data or iTunes media meta-data), you'll find that it's
441 now much easier for you to access these namespaced elements. You always
442 could access them, but in previous versions you might have to write
443 something ugly like $(/{http://www.w3.org/2003/01/geo/wgs84_pos#}lat)
444 just to get at the value of a `<geo:lat>` tag. Now, as long as you use
445 the same mnemonic codes that the feed producer used, you should always
446 be able to write a nice, simple expression like $(/geo:lat) to get the
447 value of a <geo:lat> tag.
448
449 * CUSTOM DIRECTORY STRUCTURE SUPPORT: if you poke at it enough, WordPress
450 is relatively flexible about where it should store admin interface code,
451 uploaded content, plugins, and a number of other things that occupy an
452 important place in the WordPress directory structure. Previous versions
453 of FeedWordPress encountered serious errors or broke entirely when used
454 with directory structures other than the default. This should now be
455 fixed: FWP now supports custom directory structures wherever WordPress
456 allows them to be customized, rather than depending on the default
457 locations. Enjoy your freedom!
458
459 * MANY NEW FILTERS AND API UTILITY FUNCTIONS FOR ADD-ON PROGRAMMERS: There
460 have been too many improvements to list them all in this ChangeLog, but
461 it means that much more power and ease for folks who are customizing
462 FeedWordPress through PHP filters or add-on modules. Fuller
463 documentation will be put up at the Wiki at feedwordpress.radgeek.org
464 soon.

468 * WORDPRESS 3.0 COMPATIBILITY / AUTHOR MAPPING INTERFACE ISSUES: I
469 resolved a couple of outstanding issues with the author mapping
470 interface (Syndication --> Authors), which were preventing new users
471 from being created correctly and author mapping rules from being set up
472 correctly. These partly had to do with new restrictions on user account
473 creation introduced in WordPress 3.0; anyway, they should now be fixed.
474
475 * MORE EFFICIENT SYNDICATED URL LOOKUPS: Several users noticed that the
476 bug fix introduced in 2010.0528 for compatibility with post-listing
477 plugins caused a lot more queries to the database in order to look up
478 numerical post IDs from the URL provided to the filter. This shouldn't
479 cause any major problems, but it is not as efficient as it could be; the
480 code now takes advantage of a more efficient way of doing things,
481 which usually will not require any additional database queries.
482
483 * SIMPLEPIE FEED UPDATE ISSUES: If you have been having significant
484 problems with getting feeds to update correctly, this may be the result
485 of some bugs in the implementation of SimplePie caching that ships with
486 WordPress (as of version 3.0). (You would most commonly experience this
487 error if you continually saw errors such as "No feed found at <...>" in
488 your updates.) Fortunately, SimplePie allows for a great deal of
489 extensibility and this allows me to work around the problem; these
490 error conditions should now be mostly eliminated when the underlying
491 feed is valid.
492
493 * UI: SHOW INACTIVE SOURCES: When you use the default unsubscribe option
494 -- which turns off the subscription to a feed while preserving the posts
495 from it and the syndication-related meta-data for the feed -- the
496 unsubscribed feed can now easily be viewed in a special "Inactive"
497 section of the Syndicated Sources page. (As a side benefit, if you've
498 accidentally, or only temporarily, turned off the subscription to a
499 feed, it is now much easier to restore the feed to being active, or to
500 delete it permanently, if you prefer.
501
502 * UI: FEED FINDER / SWITCH FEED INTERFACE IMPROVEMENTS: changes to styling
503 and options for the feed finder / switch feed, which should now make it
504 easier, in some cases, to find alternative feeds, and make interface
505 options more clearly visible.
506
507 * FILTERS: `syndicated_item_published` and `syndicated_item_updated` NOW
508 PROPERLY AFFECT THE DATING OF POSTS. These filters used to affect some
509 date-related settings, but not others -- and, most importantly, not the
510 final date that is set for a post's publication or last-modified date
511 in the WordPress database. Now, they do affect that, as they should.
512 (Filters should receive, and return, a long integer, representing a Unix
513 epoch relative timestamp.)
514
515 * MAGIC URL TO CLEAR THE CACHE: Suppose that you need to clear the feed
516 cache, for whatever reason; suppose, even, that you need to clear it on
517 a regular basis. One way you might do this is by logging into the
518 FeedWordPress administrative interface and going to Syndication -->
519 Performance. Another way you might do it, now, is to simply send an
520 HTTP request to a magic URL provided by FeedWordPress: if your blog is
521 at example.com, the URL would be <http://example.com/?clear_cache=1>
522
523 = 2010.0602 =
524
525 * CATEGORY BOX INTERFACE ELEMENT FIXED FOR WP 3.0: Stylesheet changes
526 between WordPress 2.9.x and the WordPress 3.0 RC caused the Categories
527 box under **Syndication --> Categories & Tags** to malfunction. This
528 has been fixed.
529
530 * LINK CATEGORY SELECTION BOX IN SYNDICATION ==> FEEDS FIXED FOR WP 2.8
531 AND 2.9: A WP 3.0 compatibility change introduced in 2010.0531
532 inadvertently broke the Syndicated Link Category selector under
533 Syndication --> Feeds & Updates in WP 2.8 and WP 2.9, causing the post
534 categories to be displayed in the selector rather than the link
535 categories. This should now be fixed so that the selector will work
536 correctly under both the current versions of WordPress and the 3.0 RC.
537
538 * MORE PERMISSIVE HANDLING OF FEEDS WITH BAD CONTENT-TYPE HEADERS: One of
539 the small advantages that MagpieRSS had over SimplePie is that it was
540 more tolerant about parsing well-formed feeds that the remote web server
541 happened to deliver with weird or incorrect HTTP Content-type headers.
542 In feeds affected by this problem, the new SimplePie parser would simply
543 fail to find a feed, due to its being led astray by the contents of the
544 Content-type header. This version includes an extension to SimplePie's
545 content-type sniffer that offers more permissive handling of the HTTP
546 headers.
547
548 * MORE FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Version 2010.0528
549 introduced code to control for cases in which elements intended for
550 item summaries are (ill-advisedly) used to carry the full text of posts;
551 past versions of FeedWordPress would simply include the full text of the
552 post in the excerpt field, but newer versions now attempt to detect
553 this condition when it arises and to head it off, by blanking out the
554 excerpt field and filling it with an automatically generated short,
555 plain text excerpt from the full content. This release broadens the
556 test conditions that indicate when an excerpt field is treated as
557 identical to the full text of the post, and should therefore improve
558 the handling of some feeds (such as Google Reader feeds) where the full
559 text of each post was still appearing in the excerpt field.
560
561 * FILTERS: `syndicated_item_published` AND `syndicated_item_updated`
562 FILTERS NOW ALLOW FILTER AUTHORS TO CHANGE POST TIMESTAMPS. You can now
563 use the `syndicated_item_published` and `syndicated_item_updated` filter
564 hooks to write filters or add-ons which directly change the post date
565 and most-recently-updated timestamps on incoming syndicated posts. Props
566 to niska for pointing out where the filters needed to be applied in
567 order to change WordPress's internal timestamps for incoming posts.
568
569 = 2010.0531 =
570
571 * PERMALINK / CUSTOM FIELDS PROBLEM RESOLVED: An issue in 2010.0528 caused
572 some posts to be imported without the proper syndication-related
573 meta-data being attached (thus causing permalinks to point back to the
574 aggregator website rather than to the source website, among other
575 problems). This problem has been resolved (and a fix has been applied
576 which will resolve the problem for any posts affected by this problem,
577 if the original post is recent enough to still be available on the feed).
578
579 * UI: The "Back End" section has been split into two separate sections --
580 "Performance" (dealing with caching, database index, and other
581 performance tweaks), and "Diagnostics" (dealing with debug mode,
582 update logging, and a number of new diagnostic tests which I will be
583 rolling out over the next few releases).
584
585 * Several minor interface bug fixes and PHP warning notices eliminated.
586
587 = 2010.0528 =
588
589 #### Compatibility ####
590
591 * SIMPLEPIE IS NOW USED TO PARSE FEEDS; NO MORE MAGPIERSS UPGRADES NEEDED:
592 One of the biggest changes in this release is that FeedWordPress no
593 longer depends on MagpieRSS to parse feeds, and has switched to the much
594 more up-to-date and flexible SimplePie feed parser, which is included as
595 a standard part of WordPress versions 2.8 and later. Using SimplePie will
596 hopefully allow for better handling of feeds going further, and will
597 allow me greater flexibility in determining how exactly the feed parser
598 will operate. It also means that FeedWordPress no longer requires
599 special upgrades to the WordPress core MagpieRSS files, and should
600 eliminate quite a bit of complexity.
601
602 * MAGPIERSS COMPATIBILITY LAYER FOR EXISTING FILTERS AND ADD-ONS: However,
603 I have also implemented a compatibility layer to ensure that existing
604 filters and add-ons for FeedWordPress which depended on the MagpieRSS
605 data format *should not be broken* by the switch to SimplePie. Going
606 forward, I recommend that new filters and add-ons be written to take
607 advantage of the SimplePie object representations of items, feeds, etc.,
608 rather than the MagpieRSS arrays, but the MagpieRSS arrays will still
609 be available and older filters should continue to work as they have in
610 the past.
611
612 * COMPATIBILITY WITH WORDPRESS 2.9.x and 3.0: This release has been tested
613 for the existing WordPress 2.9.x branch and with the upcoming release of
614 WordPress 3.0. Changes in the user interface JavaScript between WordPress
615 2.8.x and WordPress 2.9 caused the tag box interface element to break in
616 the Syndication --> Categories & Tags settings page; changes in the API
617 functions for adding new authors caused fatal errors under certain
618 conditions in WordPress 3.0. These breakages have been fixed.
619
620 * DROPPED LEGACY SUPPORT FOR WORDPRESS PRIOR TO 2.8: Because SimplePie is
621 not included with versions of WordPress prior to 2.8, I have chosen to
622 drop legacy support for WordPress versions 1.5 through 2.7. If you are
623 using FeedWordPress with a version of WordPress before 2.8, you will
624 have to upgrade your installation of WordPress in order to take
625 advantage of this release.
626
627 * PHP 5.3 COMPATIBILITY: A couple of compatibility issues, which were
628 causing fatal errors amd ugly warnings for users of PHP 5.3,
629 have been eliminated.
630
631 #### Features and Processing ####
632
633 * INTERFACE REORGANIZATION: The interface restructuring, began with
634 Version 2009.0612, has been completed. Catch-all settings pages have
635 been eliminated entirely for pages that cover each aspect of handling
636 a feed: Feeds & Updates, Posts & Links, Authors, Categories & Tags,
637 and Back End handling of the database and diagnostic information.
638 Extensive new interface hooks allow add-on modules to significantly
639 change or extend the FeedWordPress admin interface and workflow.
640
641 * STORING INFORMATION FROM THE FEED IN CUSTOM FIELDS: Many users
642 have written to request the ability to store information from elements
643 in the feed in a custom field on each post. (So that, for example, if
644 post includes a `itunes:duration` element, you could store the contents
645 in a Custom Field called `duration` on the post (for a Theme to access
646 later). The Custom Post Settings under Syndication --> Posts & Links now
647 allow you to access any item or feed tag, using a syntax similar to
648 a much-simplified version of XPath. See Posts & Links settings for
649 details.
650
651 * UPDATE-FREEZING ON MANUALLY EDITED POSTS: FeedWordPress now allows you
652 to mark posts that have been manually edited, so that the changes you
653 make will not be overwritten by later updates from the feed. If you make
654 manual edits to a particular post, just check the "Manual editing"
655 checkbox in order to protect your changes from being overwritten. If you
656 want to block *all* posts from being updated after they are imported
657 for the first time, a new "Updated Posts" setting in Posts & Links
658 allows you to freeze all posts from a particular feed, or all syndicated
659 posts.
660
661 * SETTING: FEED-BY-FEED SETTINGS FOR WHERE PERMALINKS POINT TO: You've
662 always been able to tell FeedWordPress whether permalinks for posts
663 should point to the original source of the story or the local copy. Now
664 you can choose different policies for different feeds, instead of one
665 global policy for all feeds. (Of course, you can still use a global
666 default if you prefer.)
667
668 * SETTING: USER CONTROL OVER TIMING BASIS. You can now determine the
669 schedule on which feeds are considered ready to poll for updates --
670 by default feeds become ready for polling after about 1 hour. You can
671 now increase or decrease the time window under Syndication --> Feeds &
672 Updates. (However, please pay *CAREFUL ATTENTION* to the recommendations
673 and DO NOT set the scheduling lower than 60 minutes unless you are
674 ABSOLUTELY SURE that you have specific permission from webmaster who
675 provides that specific feed to poll more frequently than that. If you
676 set this too low (and about 60 minutes is the polite minimum if you
677 haven't been given a different figure), most webmasters will consider
678 the frequent hits on their server as rude, or even downright abusive.
679
680 * OTHER SETTINGS: New settings also include the ability to stop FWP from
681 resolving relative URLs within syndicated content, and the ability to
682 choose whether FeedWordPress should indicate the comment feed from the
683 original source, or the local comment feed, when providing the comment
684 feed URL for a syndicated post.
685
686 #### Parsing ####
687
688 * BETTER DATE HANDLING -- FEWER FLASHBACKS TO 1969 and 1970: FeedWordPress
689 has made some bugfixes and some improvements in the logic for parsing
690 dates. This should allow FeedWordPress to correctly parse more dates in
691 more feeds; and, in the last resort, when FeedWordPress fails to
692 correctly parse a date, to fall back to a more intelligent default. This
693 should hopefully avoid most or all error conditions that have resulted
694 in articles being erroneously dated to the dawn of the Unix epoch
695 (31 December 1969 or 1 January 1970).
696
697 * FULL-TEXT "EXCERPTS" NOW PROPERLY SHORTENED. Based on a straightforward
698 reading of the existing RSS specs, it's reasonable for the
699 rss:description element to be read as a plaintext summary or excerpt for
700 the item containing the description -- with the full text of the item,
701 if available, in another, better-suited element, such as the de facto
702 standard content:encoded extension element. The problem is that uses of
703 RSS rarely have much to do with anything like a straightforward reading
704 of the specs. As a result, many actual RSS producers in the wild put the
705 full text of the article in a description element. But since
706 FeedWordPress has treated this text as a summary, this produces
707 aggregated posts with lengthy "excerpts" containing the full text of the
708 article. This release of FeedWordPress fixes the problem by doing a
709 little digging before treating rss:description as a summary: if the
710 description element is used properly as a plain text summary, then
711 FeedWordPress will take the summary provided by the feed, rather than
712 recreating its own excerpt from the full text; but if an RSS item has no
713 full-text element other than description, FeedWordPress will treat the
714 description element as the full text of the article, and generate a
715 shortened excerpt automatically from that text.
716
717 #### API ####
718
719 * TEMPLATE API: new template tags `get_local_permalink()` and
720 `the_local_permalink()` allow you to access the permalink for a post on
721 your aggregator site, even when FeedWordPress is rewriting permalinks to
722 point to the original source site.
723
724 * NEW HOOKS FOR ADD-ONS AND FILTERS: I have added a number of new hooks
725 which allow add-on modules to filter more precisely, gather information
726 at more points, and to enhance the FeedWordPress admin interface. For
727 a list of new hooks and documentation, see the FeedWordPress
728 documentation wiki at
729 <http://feedwordpress.radgeek.com/wiki/add-ons-and-filters>
730
731 * FILTER API: A number of new utility methods have been added to the
732 SyndicatedPost class to make it easier for filters and add-ons to
733
734 * FILTER API: Globals $fwp_channel and $fwp_feedmeta DEPRECATED. These
735 global variables, originally introduced to allow filters access to
736 information about the source feed in `syndicated_item` filters (which
737 were passed in through global variables rather than as parameters
738 because of a bug in WP 1.5 which was then fixed in 1.5.1) have been
739 DEPRECATED. If you have any filters or add-ons which still depend on
740 these global variables, you should see about fixing them to access data
741 about the source feed using the SyndicatedPost::link element instead.
742 For documentation, see the FeedWordPress documentation wiki at
743 <http://feedwordpress.radgeek.com/wiki/syndicatedpost> and
744 <http://feedwordpress.radgeek.com/wiki/syndicatedlink>.
745
746 * DIAGNOSTICS: I've included a number of new diagnostic options and
747 messages, which should allow an experienced user to better investigate
748 any problems that may crop up.
749
750 #### Bug Fixes ####
751
752 * BUGFIX: & IN PERMALINKS NO LONGER CAUSING ATOM OR HTML VALIDATION
753 EFFORTS: Many users reported an issue in which syndicating a feed with
754 special XML characters in the URLs (& was the most common, since it is
755 used to separate HTTP GET parameters) would cause the aggregator's
756 feeds to produce invalid (malformed) XML. This update addresses the
757 issue in Atom feeds. Unfortunately, it has not been technically possible
758 to address the problem in RSS 2.0 feeds, due to limitations on
759 WordPress's internal templates for RSS feeds.
760
761 * BUGFIX: BROKEN URLS IN "POPULAR POSTS" AND SIMILAR PLUGINS SHOULD NO
762 LONGER BE BROKEN. A number of users noticed an issue where plugins and
763 templates that listed posts in locations outside of the post loop
764 (for example, "Popular Posts"-style plugins that listed posts in the
765 sidebar), often produced the wrong URL for post links. (Typically, all
766 the posts listed would get the same wrong URL.) This should now be
767 fixed. Thanks to Björn for sending in a quick fix!
768
769 * MINOR BUGFIXES: This release includes a number of fixes to minor bugs
770 and compatibility issues, including: silent failures of the "Syndicate"
771 button, "Illegal Offset Type" error messages from MagpieRSS, and others.
772
773 = 2009.0707 =
774
775 * BUGFIX: WORDPRESS 2.8 AJAX COMPATIBILITY ISSUES RESOLVED (blank or
776 truncated "Syndicated Sites" administration page): Due to changes in the
777 AJAX interface elements between WordPress 2.7 and WordPress 2.8, several
778 FeedWordPress users encountered an issue where the front "Syndication"
779 page in the FeedWordPress administrative interface would come up blank,
780 without the normal "Syndicated Sites" list and "Update" control, or
781 sometimes wth the boxes visible but one or both of them truncated, with
782 only the title bar. This issue should now be resolved: with the new
783 version of FeedWordPress, the compatibility issue that caused the
784 disappearance should be eliminated, and if boxes are shown with only
785 their handle visible, you should once again be able to drop down the
786 rest of the box by clicking once on its title bar.
787
788 * BUGFIX: TAG SETTING WIDGET FIXED. Due to changes in interface elements
789 between WordPress 2.7 and WordPress 2.8, people using FeedWordPress with
790 WordPress 2.8 found that the widget for setting tags to be applied to
791 all syndicated posts, or all syndicated posts from a particular feed,
792 no longer displayed "Add" and "Remove" buttons for individual tags. This
793 issue has now been fixed, and the tagging widget should once again work
794 more or less exactly like the tagging widget for individual posts in the
795 normal WordPress admin interface.
796
797 = 2009.0618 =
798
799 * BUGFIX: MYSTERY ERRORS WITH WITH WP_Http_Fsockopen HTTP TRANSPORT
800 ELIMINATED: Thanks to a combination of a subtle bug in FeedWordPress,
801 and changes to the HTTP transport code in WordPress, a number of users
802 encountered an error in which any time they attempted to add a new feed
803 through the FeedFinder interface, FeedWordPress would fail and display
804 an HTTP request failure diagnostic message. The subtle bug has been
805 fixed, and with it, most of these errors should now be eliminated.
806
807 Be sure to upgrade your MagpieRSS to the most recent MagpieRSS version
808 after you have insalled FeedWordPress 2009.0618, or this bug fix will
809 not take effect.
810
811 = 2009.0613 =
812
813 * INTERFACE/BUGFIX: WORDPRESS 2.8 CATEGORY BOX FIX. Thanks to a subtle
814 change in class names between the WordPress 2.7 and 2.8 stylesheets,
815 category boxes in the FeedWordPress settings interface tended to overflow
816 and have a lot of messy-looking overlapping text under WordPress 2.8.
817 This has now been fixed.
818
819 * FeedFinder FAILURE DIAGNOSTICS: When FWP's FeedFinder fails to find any
820 feeds at a given URL (for example, when you are trying to add a
821 subscription through the administrative interface and you run into an
822 error message), FeedWordPress now provides more diagnostic information
823 for the reasons behind the failure. If that helps you, great; if not,
824 it should help me respond more intelligently to your support request..
825
826 = 2009.0612 =
827
828 * WORDPRESS 2.8 COMPATIBILITY: FeedWordPress 2009.0612 has been tested for
829 compatibility with the recent version 2.8 release of WordPress.
830
831 * INTERFACE RESTRUCTURING: In order to avoid settings posts from becoming
832 too crowded, and to modularize and better organize the user interface,
833 new "Posts" and "Categories & Tags" subpages have been created under the
834 "Syndication" menu. "Posts" controls settings for individal syndicated
835 posts (such as publication status, comment and ping status, whether or
836 not to use the original location of the post as the permalink, whether
837 or not to expose posts to formatting filters, and so on). "Categories &
838 Tags" controls settings for assigning new syndicated posts to categories
839 and tags, such as categories or tags to apply to all syndicated posts,
840 and how to handle categories that do not yet exist in the WordPress
841 database. These subpages, like the Authors subpage, handle settings for
842 the global default level and for individual syndicated feeds.
843
844 Corresponding to these new subpages, the old Syndication Settings and
845 Feed Settings subpages have been cleaned up and simplified, and now only
846 link to the appropriate subpages for options that can be set in the
847 Posts, Authors, or Categories & Tags subpages.
848
849 * FEATURE: ADD CUSTOM SETTINGS TO EACH SYNDICATED POST: FeedWordPress has
850 long had an interface for creating custom settings for each syndicated
851 *feed* which could be retrieved in templates using the `get_feed_meta()`
852 template function. But it had no feature for adding custom fields to
853 each individual syndicated *post*. In response to requests from users, I
854 have added the ability to apply custom fields to each individual
855 syndicated post, using the new Syndication --> Posts subpage. You can
856 set up custom fields to be applied to every syndicated post, or custom
857 fields to be applied to syndicated posts from a particular feed.
858
859 * FEATURE: MAGPIERSS VERSION CHECK AND UPGRADE: FeedWordPress will attempt
860 to determine whether or not you are using the upgraded version of
861 MagpieRSS that comes packaged with FeedWordPress. If not, it will throw
862 an error on admin pages, and, if you are a site administrator, it will
863 give you the option to ignore the error message, or to attempt an
864 automatic upgrade (using a native file copy). If the file copy fails,
865 FeedWordPress will offer some guidance on how to perform the upgrade
866 manually.
867
868 * BLANK POSTS PROBLEM NO LONGER OCCURS WITH OLD & BUSTED MAGPIERSS: Due
869 to the fact that I relied on a content normalization that occurs in my
870 upgraded version of MagpieRSS, but not in the old & busted version of
871 MagpieRSS that ships with WordPress, until this version, if you tried to
872 syndicate an Atom feed without having performed the (*strongly
873 recommended*) MagpieRSS upgrade, all of the posts would come up with
874 completely blank contents. That's not because MagpieRSS couldn't read
875 the data, but rather because the new Magpie version puts that data in a
876 location where the old version doesn't, and I was only looking in that
877 newer location. Now it checks for both, meaning that posts will continue
878 to display their contents even if you don't upgrade MagpieRSS. (But you
879 **really should** upgrade it, anyway.)
880
881 * BUGFIX: RELATIVE URI RESOLUTION FOR POST CONTENT RESTORED. Some time
882 back, I added support for resolving relative URIs against xml:base on
883 feeds that support it to the MagpieRSS upgrade in FeedWordPress. Then I
884 took out code that did the same thing from the main FeedWordPress code.
885 Of course, the problem is that some people, even though it is clearly
886 stupid or evil to do so, still include relative URIs for images or links
887 in posts on feed formats that do *not* adequately support xml:base
888 (notably, RSS 2.0 feeds). In response to a user request, I have added
889 this functionality back in, so that MagpieRSS will resolve any relative
890 URIs that it knows how to resolve using xml:base, and then FeedWordPress
891 will attempt to resolve any relative URIs that are left over afterwards.
892
893 * BUGFIX: INTERFACE OPTION FOR SETTING SYNDICATED POST PUBLICATION STATUS
894 ON A FEED-BY-FEED BASIS HAS BEEN RESTORED: Due to a version-checking
895 bug, users of WordPress 2.7.x lost an option from the "Edit a syndicated
896 feed" interface which allowed them to determine whether newly syndicated
897 posts should be published immediately, held as "Pending Review," saved
898 as drafts, or saved as private posts. (The option to change this
899 setting globally remained in place, but users could no longer set it on
900 a feed-by-feed basis.) The version-checking bug has been fixed, and the
901 option has been restored.
902
903 * BUGFIX: "ARE YOU SURE?" FATAL ERROR ELIMINATED AND SECURITY IMPROVED:
904 Under certain circumstances (for example, when users have configured
905 their browser or proxy not to send HTTP Referer headers, for privacy or
906 other reasons), many features in the FeedWordPress administrative
907 interface (such as adding new feeds or changing settings) would hit a
908 fatal error, displaying only a cryptic message reading "Are you sure?"
909 and a blank page following it. This problem has been eliminated by
910 taking advantage of WordPress's nonce functions, which allow the
911 security check which ran into this error to work properly even without
912 receiving an HTTP Referer header. (N.B.: WordPress's nonce functions
913 were first introduced in WordPress 2.0.3. If you're using FeedWordPress
914 with an older version of WordPress, there's no fix for this problem:
915 you'll just need to turn Referer headers back on. Sorry.)

917 * BUGFIX: MANUALLY-ALTERED POST STATUS, COMMENT STATUS, AND PING STATUS NO
918 LONGER REVERTED BY POST UPDATES: If you manually altered the post status,
919 comment status, or ping status of a syndicated post from what it was set
920 to when first syndicated -- for example, if you had a feed that was set
921 to bring in new posts as "Pending Review," and you then marked some of
922 the pending posts as "Published" and others as "Unpublished" -- then
923 in previous versions of FeedWordPress, these manual changes to the
924 status would be lost -- so that, for example, your Published or Unpublished
925 articles would revert to Pending Review -- if the source feed made any
926 upates to the item. This could make the Pending Review feature both
927 unreliable and also extremely frustrating to work with. The good news is
928 that this bug has since been fixed: if you manually update the status
929 of a post, it will no longer be reverted if or when the post is updated.
930
931 * BUGFIX: OCCASIONAL FATAL ERROR ON UPDATE ELIMINATED: Under certain
932 limited conditions (specifically, when both the title and the content of
933 a post to be updated are empty), an attempt to update the post would
934 result in a fatal error. This has been fixed.
935
936 * INTERFACE: "CONFIGURE SETTINGS" CONVENIENCE LINK ADDED TO CONFIRMATION
937 MESSAGE WHEN A NEW FEED IS ADDED: When you add a new subscription to
938 FeedWordPress, the message box that appears to confirm it now includes a
939 handy link to the feed's settings subpage, so that you can quickly set
940 up any special settings you may want to set up for the new feed, without
941 having to hunt through the list of all your other subscriptions to pick
942 out the new one.
943
944 * INTERFACE: SIMPLIFYING AND CLARIFYING AUTOMATIC UPDATES SETTINGS. I have
945 removed an interval setting for the cronless automatic updates which has
946 confused many FeedWordPress users. In past versions of FWP, when you
947 turned on automatic updates, you would be presented with a time interval
948 setting which controlled how often FeedWordPress would check for feeds
949 ready to be polled for updates. (That is, it DID NOT control how often
950 feeds *would be polled*; it controlled how often FeedWordPress would
951 *check* for feeds that *had become ready to poll*. The schedule on which
952 feeds became ready for polling was still controlled either by requests
953 encoded in elements within the feed itself, or else according to an
954 internal calculation within FeedWordPress, averaging out to about 1 hour,
955 if the feed did not include any scheduling request elements.) Since many
956 users very often (and understandably) confused the purpose of this
957 setting, and since the setting is for a feature that's actually very
958 unlikely to require any manual control by the user, I have removed the
959 setting; FeedWordPress now simply uses the default value of checking for
960 feeds to poll every 10 minutes.
961
962 * FEEDFINDER PERFORMANCE IMPROVEMENT: FeedWordPress's FeedFinder class
963 now uses `array_unique()` to make sure that it doesn't waste time
964 repeatedly iterating over and polling the same URI. Props to Camilo
965 (<http://projects.radgeek.com/2008/12/14/feedwordpress-20081214/#comment-20090122160414>).
966
967 = 2008.1214 =
968
969 * WORDPRESS 2.7 COMPATIBILITY: FeedWordPress has been tested for
970 compatibility with the newly released WordPress 2.7. WordPress 2.7 has
971 deprecated the Snoopy library for HTTP requests, which caused a fatal
972 error for users who had not installed the MagpieRSS upgrade (or whose
973 installation of the MagpieRSS upgrade was overwritten by a recent update
974 of WordPress). FeedWordPress now handles things gracefully when Snoopy
975 is not immediately available.
976
977 * INTERFACE SPIFFED UP: Interface elements have been updated so that
978 FeedWordPress's management interface fits in more naturally with the
979 WordPress 2.7 interface (including a new logo and a number of small
980 interface tweaks).
981
982 * BUG WITH TAGS FOR SYNDICATED ARTICLES FIXED: Several users encountered a
983 bug with the option to add tags to all syndicated posts under
984 Syndication --> Settings -- if you told FeedWordPress to add more than
985 one tag to all syndicated posts, instead of doing so correctly, it would
986 add a *single* tag instead, whose name was composed of the names of all
987 the tags you asked it to add. This bug was the result of nothing more
988 dignified than a typographical error on my part. It has now been fixed.
989
990 * MORE INFORMATION AVAILABLE WHEN FEEDWORDPRESS CAN'T FIND A FEED: When
991 you enter a URL for a new syndication source, FeedWordPress uses a
992 simple feed-finding algorithm (originally based on Mark Pilgrim's
993 Universal Feed Finder) to try to determine whether the URL is the URL
994 for a feed, or, if the URL points to an ordinary website rather than to
995 a feed, whether there is a feed for that website. All well and good, but
996 if FeedWordPress failed to find a feed, for whatever reason, it would
997 typically return nothing more than a nasty little note to the effect of
998 "no feed found," without any explanation of what went wrong.
999 FeedWordPress now keeps track of error conditions from the HTTP
1000 requests that it uses in the course of looking for the feed, and so may
1001 be able to give you a bit more information about the nature of the
1002 problem if something goes wrong.
1003
1004
1005 = 2008.1105 =
1006
1007 * INTERFACE RESTRUCTURING AND SYNDICATION --> AUTHORS PAGE: As a first
1008 step towards modularizing and better organizing the user interface, a
1009 new "Authors" subpage has been created under the Syndication menu, which
1010 controls settings for syndicated authors, both at the global default
1011 level and at level of individual syndicated feeds.
1012
1013 * BUG RELATED TO THE ATTRIBUTION OF POSTS TO THE WRONG AUTHOR FIXED: Some
1014 users encountered an issue in which posts by different authors on
1015 different blogs -- especially blogs generated by Blogger -- were
1016 mistakenly attributed to a single author. The problem was caused by the
1017 way in which FeedWordPress matches syndicated authors to user accounts
1018 in the WordPress database: normally, if two feeds each list an author
1019 with the same e-mail address, they are counted as being the same person.
1020 Normally this works well, but it creates an issue in cases where
1021 blogging software assigns a single anonymous e-mail address to users who
1022 do not want their real e-mail address published. This is, for example,
1023 what Blogger does (by giving all users a default e-mail address of
1024 <noreply@blogger.com> if they don't want their own e-mail address
1025 listed). FeedWordPress now allows the user to correct for this problem
1026 with a couple of new settings under **Syndication --> Authors**, which
1027 allow users to turn off e-mail based author matching for particular
1028 addresses, or, if desired, to turn it off entirely. By default, e-mail
1029 based author matching is still turned on, but disabled for a list of
1030 known generic e-mail addresses. Right now, the "list" consists entirely
1031 of <noreply@blogger.com>; if you know other addresses that should be
1032 added, please [contact me](http://radgeek.com/contact) to let me know.
1033
1034 Please note that if you have already encountered this issue on your
1035 blog, upgrading FeedWordPress will prevent it from re-occurring in the
1036 future, but you still need to do two other things to fix the existing
1037 problem on your blog.
1038
1039 First, for each feed where posts have been mis-attributed, you need to
1040 change the existing author mapping rules to re-map a a syndicated
1041 author's name to the proper target account. Go to **Syndication -->
1042 Authors**, select the feed you want to change from the drop-down list,
1043 and then change the settings under the "Syndicated Authors" section.
1044 (You will probably need to select "will be assigned to a new user..." to
1045 create a new user account with the appropriate name.)
1046
1047 Second, for each feed where posts have been mis-attributed, you need to
1048 re-assign already-syndicated posts that were mis-attributed to the
1049 correct author. You can do that from **Syndication --> Authors** by
1050 using the author re-assignment feature, described below.
1051
1052 * AUTHOR RE-ASSIGNMENT FOR A PARTICULAR FEED: The author settings page
1053 for each syndicated feed, under **Syndication --> Authors**, now
1054 includes an section titled "Fixing mis-matched authors," which provides
1055 an interface for re-assigning or deleting all posts attributed to a
1056 particular author on a particular feed.
1057
1058 * SUPPORT FOR `<atom:source>` ELEMENT IN SYNDICATED FEEDS: Some feeds
1059 (for example, those produced by FeedWordPress) aggregate content from
1060 several different sources, and include information about the original
1061 source of the post in an `<atom:source>` element. A new setting under
1062 **Syndication --> Options** allows you to control what FeedWordPress
1063 will report as the source of posts syndicated from aggregator feeds in
1064 your templates and feeds: you can have FeedWordPress report that the
1065 source of a post is the aggregator feed itself, or you can have it
1066 report that the source of a post is the original source that the
1067 aggregator originally syndicated the post from.
1068
1069 By default, FeedWordPress will report the aggregator, not the original
1070 source, as the source of a syndicated item.
1071
1072 * LOAD BALANCING AND TIME LIMITING FEATURES FOR UPDATES: Some users have
1073 encountered issues due to running up against PHP execution time limits
1074 during the process of updating large syndicated feeds, or a very large
1075 set of syndicated feeds. FeedWordPress now has a feature that allows you
1076 to limit the total amount of time spent updating a feed, through the
1077 "Time limit on updates" setting under **Syndication --> Options**. By
1078 turning on this setting and adjusting the time limit to a low enough
1079 figure to avoid your PHP installation's time-out setting. (PHP execution
1080 time limits are usually in the vicinity of 30 seconds, so an update
1081 time limit of 25 seconds or so should provide plenty of time for updates
1082 while allowing a cushion of time for other, non-update-related functions
1083 to do their work.)
1084
1085 If feed updates are interrupted by the time limit, FeedWordPress uses
1086 some simple load balancing features to make sure that updates to other
1087 feeds will not be blocked by the time-hogging feed, and will also make
1088 sure that when the interrupted update is resumed, FeedWordPress will
1089 skip ahead to resume processing items at the point at which it was
1090 interrupted last time, so that posts further down in the feed will
1091 eventually get processed, and not get blocked by the amount of time it
1092 takes to process the items higher up in the feed.
1093
1094 * `guid` INDEX CREATION BUTTON: FeedWordPress frequently issues queries on
1095 the `guid` column of the WordPress posts database (since it uses post
1096 guid URIs to keep track of which posts it has syndicated). In very large
1097 FeedWordPress installations, you can often significantly improve
1098 performance by creating a database index on the `guid` column, but
1099 normally you would need to poke around with MySQL or a tool like
1100 phpMyAdmin to do this. FeedWordPress can now save you the trouble: to
1101 create an index on the `guid` column, just go to
1102 **Syndication --> Options**, and mash the button at the bottom of the
1103 "Back End" section.
1104
1105 = 2008.1101 =
1106
1107 * INTERFACE BUG THAT PREVENTED ADDING NEW SITES FIXED: The UI reforms in
1108 FWP 2008.1030 unintentionally introduced a bug that prevents clean
1109 installations of FeedWordPress from providing an input box for adding
1110 new feeds to the list of syndicated feeds. This bug has been fixed.
1111
1112 = 2008.1030 =
1113
1114 * WORDPRESS 2.6 COMPATIBILITY: FeedWordPress should now be compatible with
1115 WordPress 2.6, and should work more or less seamlessly with the new post
1116 revision system. A bug which caused multiple new revisions to be created
1117 for posts on certain feeds, regardless of whether or not the item had
1118 been updated, has been fixed.
1119
1120 * INTERFACE IMPROVEMENTS: The user interface has been substantially
1121 restyled to fit in better with the visual style of WordPress 2.5 and
1122 2.6.
1123
1124 * YOUTUBE BUG FIXED: POSTS SYNDICATED THROUGH AN AUTOMATIC UPDATE ARE NO
1125 LONGER STRIPPED OF `<OBJECT>` TAGS AND CERTAIN OTHER HTML ELEMENTS: Due
1126 to the way that some versions of WordPress process posts that are
1127 inserted into the database when no user is logged in, many users
1128 experienced an issue where YouTube videos and other content using the
1129 HTML `<object>` tag would be stripped out of posts that were syndicated
1130 during an automatic update. (Posts that were syndicated through manual
1131 updates from within the WordPress Dashboard were not affected, because
1132 the issue does not arise when an update is executed under a logged-in
1133 administrator's credentials.) This bug has now been fixed; YouTube
1134 videos and other content using `<object>` tags should now appear
1135 properly in syndicated posts, regardless of the way in which the post
1136 was syndicated.
1137
1138 * AJAX BUGS FIXED: Bugs which blocked the normal operation of WordPress
1139 2.5's AJAX interface elements when FeedWordPress was activated have been
1140 fixed.
1141
1142 * TAG SUPPORT: A couple of features have been introduced to take advantage
1143 of the tagging features in WordPress 2.3.x, 2.5.x, and 2.6.x. Now, when
1144 unfamiliar categories are encountered for posts on a feed, you can
1145 choose for FeedWordPress (1) to drop the category; (2) to drop the
1146 category and to filter out any post that does not match at least one
1147 familiar category; (3) to create a new category with that name, or,
1148 now, you can also have FeedWordPress (4) create a new *tag* with that
1149 name. This option can be set site-wide under Syndication --> Options,
1150 or it can be set on a feed-by-feed basis in a feed's Edit screen.
1151
1152 In addition, you can now set particular tags to apply to all incoming
1153 syndicated posts, under Syndication --> Options, or you can set tags
1154 to apply to all incoming syndicated posts from a particular feed in that
1155 feed's Edit screen.
1156
1157 * FORMATTING FILTERS: There is a new option available under Syndication ->
1158 Options which allows users to choose whether or not to expose syndicated
1159 posts to being altered by formatting filters. By default, FeedWordPress
1160 has always protected syndicated posts (which are already in display-ready
1161 HTML when they are syndicated) from being reformatted by formatting
1162 filters. However, this approach means that certain plugins which depend
1163 on formatting filters (for example, to add "Share This" bars or relevant
1164 links to the end of a post) are blocked from working on any syndicated
1165 posts. If you want to use one of these plugins together with
1166 FeedWordPress, you can now do so by changing the "Formatting Filters"
1167 setting from "Protect" to "Expose."
1168
1169 * `<atom:source>` ELEMENTS NOW INCLUDED IN ATOM FEED: Atom 1.0 provides
1170 a standard method for aggregators to indicate information about the original source of
1171 a syndicated post, using the `<atom:source>` element. FeedWordPress now
1172 introduces standard `<atom:source>` elements including the title, homepage, and
1173 feed URI of the source from which a syndicated post was syndicated. Cf.
1174 <http://www.atomenabled.org/developers/syndication/atom-format-spec.php#element.source>
1175
1176 * MODULARIZATION OF CODE: The code for different elements of FeedWordPress
1177 has been broken out into several modules for easier inspection,
1178 documentation, and maintenance of the code.
1179
1180 * VERSIONING SCHEME CHANGED: FeedWordPress's feature set has proven stable
1181 enough that it can now be removed from beta status; a good thing, since
1182 I was very quickly running out of version numbers to use. New releases
1183 of FeedWordPress will have version numbers based on the date of their
1184 release.
1185
1186 = 0.993 =
1187
1188 * WORDPRESS 2.5.1 COMPATIBILITY: FeedWordPress should now be compatible
1189 with WordPress 2.5.1.
1190
1191 * WORDPRESS 2.5 INTERFACE IMPROVEMENTS: FeedWordPress's Dashboard
1192 interface has undergone several cosmetic changes that should help it
1193 integrate better with the WordPress Dashboard interface in WordPress
1194 version 2.5.x.
1195
1196 * SYNDICATED POSTS CAN BE MARKED AS "PENDING REVIEW": WordPress 2.3 users
1197 can now take advantage of WordPress's new "Pending Review" features for
1198 incoming syndicated posts. Posts marked as "Pending Review" are not
1199 published immediately, but are marked as ready to be reviewed by an
1200 Administrator or Editor, who can then choose to publish the post or
1201 hold it back. If you want to review syndicated posts from a particular
1202 feed, or from all feeds, before they are posted, then use
1203 Syndication --> Syndicated Sites --> Edit or Syndication --> Options to
1204 change the settings for handling new posts.
1205
1206 * AWARE OF NEW URI FOR del.icio.us FEEDS: Previous releases of
1207 FeedWordPress already automatically split del.icio.us tags up
1208 appropriately appropriately when generating categories. (del.icio.us
1209 feeds smoosh all the tags into a single `<dc:subject>` element,
1210 separated by spaces; FeedWordPress un-smooshes them into multiple
1211 categories by separating them at whitespace.) Unfortunately, del.icio.us
1212 recently broke the existing behavior by changing host names for their
1213 feeds from del.icio.us to feeds.delicious.com. Version 0.993 accounts
1214 for the new host name and un-breaks the tag splitting.
1215
1216 = 0.992 =
1217
1218 * AUTHOR RE-MAPPING: FeedWordPress now offers considerable control over
1219 how author names on a feed are translated into usernames within the
1220 WordPress database. When a post by an unrecognized author comes in,
1221 Administrators can now specify any username as the default username to
1222 assign the post to by setting the option in Syndication --> Options
1223 (formerly FeedWordPress only allowed you to assign such posts to user
1224 #1, the site administrator). Administrators can also create re-mapping
1225 rules for particular feeds (under Syndication --> Syndicated Sites -->
1226 Edit), so that (for example) any posts attributed to "Administrator"
1227 on the feed <http://praxeology.net/blog/feed/> will be assigned to
1228 a user named "Roderick T. Long," rather than a user named
1229 "Administrator." These settings also allow administrators to filter out
1230 posts by particular users, and to control what will happen when
1231 FeedWordPress encounters a post by an unrecognized user on that
1232 particular feed.
1233
1234 * BUG RELATED TO URIS CONTAINING AMPERSAND CHARACTERS FIXED: A bug in
1235 WordPress 2.x's handling of URIs in Blogroll links created problems for
1236 updating any feeds whose URIs included an ampersand character, such as
1237 Google News RSS feeds and other feeds that have multiple parameters
1238 passed through HTTP GET. If you experienced this bug, the most likely
1239 effect was that FeedWordPress simply would not import new posts from a
1240 feed when instructred to do so, returning a "0 new posts" response. In
1241 other cases, it might lead to unpredictable results from feed updates,
1242 such as importing posts which were not contained in the feed being
1243 syndicated, but which did appear elsewhere on the same website. This bug
1244 has, hopefully, been resolved, by correcting for the bug in WordPress.
1245
1246 = 0.991 =
1247
1248 * WORDPRESS MU COMPATIBILITY: FeedWordPress should now be compatible with
1249 recent releases of WordPress MU. Once FeedWordPress is made available
1250 as a plugin, each individual blog can choose to activate FeedWordPress
1251 and syndicate content from its own set of contributors.
1252
1253 * DISPLAY OF MAGPIE WARNINGS: A number of MagpieRSS warnings or error
1254 messages that were displayed when performing an automatic update are
1255 no longer displayed, unless debugging parameters have been explicitly
1256 enabled.
1257
1258 * BUG RELATED TO INTERNATIONAL CHARACTERS IN AUTHOR NAMES FIXED: Due to a
1259 subtle incompatability between the way that FeedWordPress generated new
1260 user information, and the way that WordPress 2.0 and later added new
1261 authors to the database, FeedWordPress might end up creating duplicate
1262 authors, or throwing a critical error message, when it encountered
1263 authors whose names included international characters. This
1264 incompatability has now been fixed; hopefully, authors with
1265 international characters in their names should now be handled properly.
1266
1267 * `<media:content>` BUG IN MAGPIERSS FIXED: A bug in MagpieRSS's handling
1268 of namespaced elements has been fixed. Among other things, this bug
1269 caused items containing a Yahoo MediaRSS `<media:content>` element (such
1270 as many of the feeds produced by wordpress.com) to be represented
1271 incorrectly, with only a capital "A" where the content of the post
1272 should have been. Feeds containing `<media:content>` elements should now
1273 be syndicated correctly.
1274
1275 * update_feedwordpress PARAMETER: You can now use an HTTP GET parameter
1276 (`update_feedwordpress=1`) to request that FeedWordPress poll its feeds
1277 for updates. When used together with a crontab or other means of
1278 scheduling tasks, this means that you can keep your blog automatically
1279 updated on a regular schedule, even if you do not choose to use the
1280 cron-less automatic updates option.
1281
1282 * Some minor interface-related bugs were also fixed.
1283
1284
1285 = 0.99 =
1286
1287 Version 0.99 adds several significant new features, fixes some bugs, and
1288 provides compatability with WordPress 2.2.x and 2.3.x.
1289
1290 * WORDPRESS 2.2 AND 2.3 COMPATIBILITY: FeedWordPress should now be
1291 compatible with WordPress version 2.2 and the upcoming WordPress
1292 version 2.3. In particular, it has been tested extensively against
1293 WordPress 2.2.3 and WordPress 2.3 Release Candidate 1.
1294
1295 * AUTOMATIC UPDATES WITHOUT CRON: FeedWordPress now allows you to
1296 automatically schedule checks for new posts without using external task
1297 scheduling tools such as cron. In order to enable automatic updates, go
1298 to **Syndication --> Options** and set "Check for new posts" to
1299 "automatically." For details, see "Automatic Feed Updates" in
1300 README.text.
1301
1302 An important side-effect of the changes to the update system is that if
1303 you were previously using the cron job and the `update-feeds.php` script
1304 to schedule updates, you need to change your cron set-up. The old
1305 `update-feeds.php` script no longer exists. Instead, if you wish to use
1306 a cron job to guarantee updates on a particular schedule, you should
1307 have the cron job fetch the front page of your blog (for example, by
1308 using `curl http://www.zyx.com/blog/ > /dev/null`) instead of activating
1309 the `update-feeds.php` script. If automatic updates have been enabled,
1310 fetching the front page will automatically trigger the update process.
1311
1312 * INTERFACE REORGANIZATION: All FeedWordPress functions are now located
1313 under a top-level "Syndication" menu in the WordPress Dashboard. To
1314 manage the list of syndicated sites, manually check for new posts on
1315 one or more feeds, or syndicate a new site, you should use the main page
1316 under **Syndication**. To change global settings for FeedWordPress,
1317 you should use **Syndication --> Options**.
1318
1319 * FILE STRUCTURE REORGANIZATION: Due to a combination of changing styles
1320 for FeedWordPress plugins and lingering bugs in the FeedWordPress admin
1321 menu code, the code for FeedWordPress is now contained in two different
1322 PHP files, which should be installed together in a subdirectory of your
1323 plugins directory named `feedwordpress`. (See README.text for
1324 installation and upgrade instructions relating to the change.)
1325
1326 * MULTIPLE CATEGORIES SETTING: Some feeds use non-standard methods to
1327 indicate multiple categories within a single category element. (The most
1328 popular site to do this is del.icio.us, which separates tags with a
1329 space.) FeedWordPress now allows you to set an optional setting, for any
1330 feed which does this, indicating the character or characters used to
1331 divide multiple categories, using a Perl-compatible regular expression.
1332 (In the case of del.icio.us feeds, FeedWordPress will automatically use
1333 \s for the pattern without your having to do any further configuration.)
1334 To turn this setting on, simply use the "Edit" link for the feed that
1335 you want to turn it on for.
1336
1337 * REGULAR EXPRESSION BUG FIXED: Eliminated a minor bug in the regular
1338 expressions for e-mail addresses (used in parsing RSS `author`
1339 elements), which could produce unsightly error messages for some users
1340 parsing RSS 2.0 feeds.
1341
1342 * DATE / UPDATE BUG FIXED: A bug in date handling was eliminated that may
1343 have caused problems if any of (1) WordPress, or (2) PHP, or (3) your
1344 web server, or (4) your MySQL server, has been set to use a different
1345 time zone from the one that any of the others is set to use. If
1346 FeedWordPress has not been properly updating updated posts, or has been
1347 updating posts when there shouldn't be any changes for the update, this
1348 release may solve that problem.
1349
1350 * GOOGLE READER BUGS FIXED: A couple of bugs that made it difficult for
1351 FeedWordPress to interact with Google Reader public feeds have been
1352 fixed. Firstly, if you encountered an error message reading "There was a
1353 problem adding the newsfeed. [SQL: ]" when you tried to add the feed,
1354 the cause of this error has been fixed. Secondly, if you succeeded in
1355 getting FeedWordPress to check a Google Reader feed, only to find that
1356 the title of posts had junk squashed on to the end of them, that bug
1357 has been fixed too. To fix this bug, you must install the newest version
1358 of the optional MagpieRSS upgrade.
1359
1360 * FILTER PARAMETERS: Due to an old, old bug in WordPress 1.5.0 (which was
1361 what was available back when I first wrote the filter interface),
1362 FeedWordPress has traditionally only passed one parameter to
1363 syndicated_item and syndicated_post filters functions -- an array
1364 containing either the Magpie representation of a syndicated item from
1365 the feed, or the database representation of a post about to be inserted
1366 into the WordPress database. If you needed information about the feed
1367 that the item came from, this was accessible only through a pair of
1368 global variables, $fwp_channel and $fwp_feedmeta.
1369
1370 Since it's been a pretty long time since WordPress 1.5.0 was in
1371 widespread usage, I have gone ahead and added an optional second
1372 parameter to the invocation of the syndicated_item and syndicated_post
1373 filters. If you have written a filter for FeedWordPress that uses either
1374 of these hooks, you can now register that filter to accept 2 parameters.
1375 If you do so, the second parameter will be a SyndicatedPost object,
1376 which, among other things, allows you to access information about the
1377 feed from which an item is syndicated using the $post->feed and the
1378 $post->feedmeta elements (where $post is the name of the second
1379 parameter).
1380
1381 NOTE THAT THE OLD GLOBAL VARIABLES ARE STILL AVAILABLE, for the time
1382 being at least, so existing filters will not break with the upgrade.
1383 They should be considered deprecated, however, and may be eliminated in
1384 the future.
1385
1386 * FILTER CHANGE / BUGFIX: the array that is passed as the first argument
1387 syndicated_post filters no longer is no longer backslash-escaped for
1388 MySQL when filters are called. This was originally a bug, or an
1389 oversight; the contents of the array should only be escaped for the
1390 database *after* they have gone through all filters. IF YOU HAVE WRITTEN
1391 ANY syndicated_post FILTERS THAT PRESUME THE OLD BEHAVIOR OF PASSING IN
1392 STRINGS THAT ARE ALREADY BACKSLASH-ESCAPED, UPDATE YOUR FILTERS
1393 ACCORDINGLY.
1394
1395 * OTHER MINOR BUGFIXES AND INTERNAL CHANGES: The internal architecture of
1396 FeedWordPress has been significantly changed to make the code more
1397 modular and clean; hopefully this should help reduce the number of
1398 compatibility updates that are needed, and make them easier and quicker
1399 when they are needed.
1400
1401 = 0.981 =
1402
1403 Version 0.981 is a narrowly targeted bugfix and compatibility release, whose
1404 main purpose is to resolve a major outstanding problem: the incompatibility
1405 between version 0.98 of WordPress and the recently released WordPress 2.1.
1406
1407 * WORDPRESS 2.1 COMPATIBILITY: FeedWordPress is now compatible with
1408 WordPress 2.1, as well as retaining its existing support for WordPress
1409 2.0 and 1.5. Incompatibilities that resulted in database warnings, fatal
1410 errors, and which prevented FeedWordPress from syndicating new posts,
1411 have been eliminated.
1412
1413 * RSS-FUNCTIONS.PHP RENAMED TO RSS.PHP: if you use the upgraded MagpieRSS
1414 replacement that's included with FeedWordPress, be sure to note that
1415 there are now *two* files to upload from the `OPTIONAL/wp-includes`
1416 subdirectory in order to carry out the upgrade: rss-functions.php and
1417 rss.php. **It is necessary to upload both files**, due to a change in
1418 the file naming scheme in WordPress 2.1, and it is necessary to do so
1419 whether you are using WordPress 2.1 or not. If you only upload the
1420 `rss-functions.php` file as in previous installations you will not have
1421 a working copy of MagpieRSS; the rss.php file contains the actual code.
1422
1423 * DATE BUG AFFECTING SOME PHP INSTALLATIONS RESOLVED: due to a subtle bug
1424 in parse_w3cdtf(), some installations of PHP encountered problems with
1425 FeedWordPress's attempt to date posts, which would cause some new posts
1426 on Atom feeds to be dated as if they had apppeared in 1969 or 1970
1427 (thus, effectively, never appearing on front page at all). This bug in
1428 the date handling should now be fixed.
1429
1430 * PHP <?=...?> SHORT FORM ELIMINATED: some installations of PHP do not
1431 allow the <?=...?> short form for printing PHP values, which was used
1432 extensively in the FeedWordPress interface code. Since this could cause
1433 fatal errors for users with the wrong installation of PHP, the short
1434 form has been replaced with full PHP echo statements, and is no longer
1435 used in FeedWordPress.
1436
1437 * BETTER USER INTERFACE INTEGRATION WITH WORDPRESS 2.x: Some minor changes
1438 have been made to help the FeedWordPress interface pages blend in better
1439 with the user interface when running under WordPress 2.x.
1440
1441 * GLOBAL CATEGORIES BUG RESOLVED: a bug that prevented some users from
1442 setting one or more categories to apply to syndicated posts from all
1443 feeds (using the checkbox interface under Options --> Syndication) has
1444 been resolved.
1445
1446 = 0.98 =
1447
1448 * WORDPRESS 2.0 COMPATIBILITY: This is a narrowly-targeted release to
1449 solve a major outstanding problem. FeedWordPress is now compatible with
1450 both WordPress 1.5 and WordPress 2.0. Incompatibilities that caused
1451 fatal SQL errors, and a more subtle bug with off-kilter counts of posts
1452 under a given category, have been resolved. FeedWordPress tests for
1453 database schema using the global $wp_db_version variable (if null, then
1454 we presume that we're dealing with WordPress 1.5).
1455
1456 NOTE: I have **not** fully tested FeedWordPress with WordPress 2.0.
1457 Further testing may reveal more bugs. However, you should now be able
1458 to get at least basic FeedWordPress functionality up and running.
1459
1460 * AUTHOR MATCHING: FeedWordPress tests several fields to see if it can
1461 identify the author of the post as a user already in the WordPress user
1462 database. In previous versions, it tested the user login, the nickname,
1463 and tested for "aliases" listed in the Profile (see documentation). FWP
1464 now also matches authors on the basis of e-mail address (*if* an e-mail
1465 address is present). This is particularly helpful for formats such as
1466 RSS 2.0, in which authors are primarily identified by e-mail addresses.
1467
1468 = 0.97 =
1469
1470 * INSTALLATION PROCEDURE: Some of the changes between 0.96 and 0.97
1471 require upgrades to the meta-data stored by FeedWordPress to work
1472 properly. Thus, if you are upgrading from 0.96 or earlier to 0.97, most
1473 FeedWordPress operations (including updates and template functions)
1474 WILL BE DISABLED until you run the upgrade procedure. Fortunately,
1475 running the upgrade procedure is easy: just go to either Options -->
1476 Syndication or Links --> Syndicated in the WordPress Dashboard and press
1477 the button.
1478
1479 * FEED FORMAT SUPPORT: Support has been added for the Atom 1.0 IETF
1480 standard. Several other elements are also newly supported
1481 (dcterms:created, dcterms:issued, dcterms:modified, dc:identifier,
1482 proper support for the RSS 2.0 guid element, the RSS 2.0 author element,
1483 the use of Atom author or Dublin Core dc:creator constructs at the feed
1484 level to identify the author of individual items, etc.)
1485
1486 N.B.: full support of several Atom 1.0 features, such as categories
1487 and enclosures, requires you to install the optional rss-functions.php
1488 upgrade in your wp-includes directory.
1489
1490 * BUG FIX: Running `update-feeds.php` from command line or crontab
1491 returned "I don't syndicate..." errors. It turns out that WordPress
1492 sometimes tramples on the internal PHP superglobals that I depended on
1493 to determine whether or not the script was being invoked from the
1494 command line. This has been fixed (the variables are now checked
1495 *before* WordPress can trample them). Note that `update-feeds.php` has
1496 been thoroughly overhauled anyway; see below for details.
1497
1498 * BUG FIX: Duplicate categories or author names. Fixed two bugs that could
1499 create duplicate author and/or category names when the name contained
1500 either (a) certain international characters (causing a mismatch between
1501 MySQL and PHP's handling of lowercasing text), or (b) characters that
1502 have a special meaning in regular expressions (causing MySQL errors when
1503 looking for the author or category due to regexp syntax errors). These
1504 should now be fixed thanks to careful escaping of names that go into
1505 regular expressions and careful matching of lowercasing functions
1506 (comparing results from PHP only to other results from PHP, and results
1507 from MySQL only to other results from MySQL).
1508
1509 * BUG FIX: Items dated December 31, 1969 should appear less often. The
1510 function for parsing W3C date-time format dates that ships with
1511 MagpieRSS can only correctly parse fully-specified dates with a
1512 fully-specified time, but valid W3C date-time format dates may omit the
1513 time, the day of the month, or even the month. Some feeds in the wild
1514 date their items with coarse-grained dates, so the optional
1515 `rss-functions.php` upgrade now includes a more flexible parse_w3cdtf()
1516 function that will work with both coarse-grained and fully-specified
1517 dates. (If parts of the date or the time are omitted, they are filled in
1518 with values based on the current time, so '2005-09-10' will be dated to
1519 the current time on that day; '2004' will be dated to this day and time
1520 one year ago.
1521
1522 N.B.: This fix is only available in the optional `rss-functions.php`
1523 upgrade.
1524
1525 * BUG FIX: Evil use of HTTP GET has been undone. The WordPress interface
1526 is riddled with inappropriate (non-idempotent) uses of HTTP GET queries
1527 (ordinary links that make the server do something with significant
1528 side-effects, such as deleting a post or a link from the database).
1529 FeedWordPress did some of this too, especially in places where it aped
1530 the WordPress interface (e.g. the "Delete" links in Links -->
1531 Syndicated). That's bad business, though. I've changed the interface so
1532 that all the examples of improper side-effects that I can find now
1533 require an HTTP POST to take effect. I think I got pretty much
1534 everything; if there's anything that I missed, let me know.
1535

1537
1538 * BUG FIX: Categories applied by `cats` setting should no longer prevent
1539 category-based filtering from working. In FeedWordPress, you can (1)
1540 apply certain categories to all syndicated posts, or all posts from
1541 a particular feed; and (2) filter out all posts that don't match one
1542 of the categories that are already in the WordPress database (allowing
1543 for simple category-based filtering; just load up WordPress with the
1544 categories you want to accept, and then tell FeedWordPress not to create
1545 new ones). However, the way that (1) and (2) were implemented meant that
1546 you couldn't effectively use them together; once you applied a known
1547 category to all syndicated posts from a particular feed, it meant that
1548 they'd have at least one familiar category (the category or categories
1549 you were applying), and that would get all posts past the filter no
1550 matter what categories they were originally from.
1551
1552 Well, no longer. You can still apply categories to all syndicated posts
1553 (using either Syndication --> Options, or the feed-level settings under
1554 Links --> Syndicated). But these categories are not applied to the post
1555 until *after* it has already passed by the "familiar categories" filter.
1556 So now, if you want, you can do category filtering and *then* apply as
1557 many categories as you please to all and only posts that pass the filter.
1558
1559 * BUG FIX: Other minor typos and HTML gaffes were fixed along the way.
1560
1561 * PERFORMANCE: get_feed_meta() no longer hits the database for information
1562 on every call; it now caches link data in memory, so FeedWordPress only
1563 goes to the database once for each syndicated link. This may
1564 substantially improve performance if your database server resources
1565 are tight and your templates make a lot of use of custom settings from
1566 get_feed_meta().
1567
1568 * API CHANGE: Link ID numbers, rather than RSS URIs, are now used to
1569 identify the feed from which a post is syndicated when you use template
1570 functions such as get_feed_meta(). The practical upshot of this is you
1571 can switch feeds, or change the feed address for a particular syndicated
1572 site, without breaking your templates for all the posts that were
1573 syndicated from the earlier URI.
1574
1575 * API CHANGE: if you have plugins or templates that make use of the
1576 get_feed_meta() function or the $fwp_feedmeta global, note that the
1577 data formerly located under the `uri` and `name` fields is now located
1578 under the `link/uri` field and the `link/name` field, respectively. Note
1579 also that you can access the link ID number for any given feed under the
1580 global $fwp_feedmeta['link/id'] (in plugins) or
1581 get_feed_meta('link/id') (in a template in post contexts).
1582
1583 * FEATURE: the settings for individual feeds can now be edited using a
1584 humane interface (where formerly you had to tweak key-value pairs in the
1585 Link Notes section). To edit settings for a feed, pick the feed that you
1586 want under Links --> Syndicated and click the Edit link.
1587
1588 * FEATURE: The "Unsubscribe" button (formerly "Delete") in Links -->
1589 Syndicated now offers three options for unsubscribing from a feed: (1)
1590 turning off the subscription without deleting the feed data or affecting
1591 posts that were syndicated from the feed (this works by setting the Link
1592 for the feed as "invisible"); (2) deleting the feed data and all of the
1593 posts that were syndicated from the feed; or (3) deleting the feed data
1594 and *keeping* the posts that were syndicated from the feed
1595 setting the Link to "Invisible" (meaning that it will not be displayed
1596 in lists of the site links on the front page, and it won't be checked
1597 for updates; (2) deleting the Link and all of the posts that were
1598 syndicated from its feed; or (3) deleting the feed data but keeping the
1599 posts that were syndicated (which will henceforward be treated as if
1600 they were local rather than syndicated posts). (Note that (1) is usually
1601 the best option for aggregator sites, unless you want to clean up the
1602 results of an error or a test.)
1603
1604 * FEATURE / BUG FIX: If you have been receiving mysterious "I don't
1605 syndicate...", or "(local) HTTP status code was not 200", or "(local)
1606 transport error - could not open socket", or "parse error - not well
1607 formed" errors, then this update may solve your problems, and if it does
1608 *not* solve them, it will at least make the reasons for the problems
1609 easier to understand. That's because I've overhauled the way that
1610 FeedWordPress goes about updating feeds.
1611
1612 If you use the command-line PHP scripting method to run scheduled
1613 updates, then not much should change for you, except for fewer
1614 mysterious errors. If you have done updates by sending periodic HTTP
1615 requests to <http://your-blog.com/path/wp-content/update-feeds.php>,
1616 then the details have changed somewhat; mostly in such a way as to make
1617 things easier on you. See the README file or online documentation on
1618 Staying Current for the details.
1619
1620 * FEATURE: FeedWordPress now features a more sophisticated system for
1621 timed updates. Instead of polling *every* subscribed feed for updates
1622 *each* time `update-feeds.php` is run, FeedWordPress now keeps track of
1623 the last time it polled each feed, and only polls them again after a
1624 certain period of time has passed. The amount of time is normally set
1625 randomly for each feed, in a period between 30 minutes and 2 hours (so
1626 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
1627 directly by the feed, which brings us to ...
1628
1629 * FEATURE: FeedWordPress now respects the settings in the `ttl` and
1630 Syndication Module RSS elements. Feeds with these elements set will not
1631 be polled any more frequently than they indicate with these feeds unless
1632 the user manually forces FeedWordPress to poll the feed (see Links -->
1633 Syndicated --> Edit settings).
1634
1635 = 0.96 =
1636
1637 * FEATURE: support has been added for enclosures in RSS 2.0 and Atom
1638 0.6+ newsfeeds. WordPress already supports adding enclosures to an
1639 item; FeedWordPress merely gets the information on the enclosure
1640 from the feed it is syndicating and plugs that information directly
1641 into the WordPress database so that (among other things) that post
1642 will have its enclosure listed in your blog's RSS 2 newsfeed.
1643
1644 Note that enclosure support requires using the optional MagpieRSS
1645 upgrade (i.e., replacing your `wp-includes/rss-functions.php` with
1646 `OPTIONAL/wp-includes/rss-functions.php` from the FWP archive)
1647
1648 * FEATURE: for completeness's sake, there is now a feed setting,
1649 `hardcode url`, that allows you to set the URI for the front page
1650 of a contributor's website manually (that is, prevent it from being
1651 automatically updated from the feed channel link on each update). To
1652 set the URI manually, put a line like this in the Link Notes section
1653 of a feed:
1654
1655 hardcode url: yes
1656
1657 You can also instruct FeedWordPress to use hardcoded URIs by default
1658 on all feeds using Options --> Syndication
1659
1660 * FEATURE: by default, when FeedWordPress finds new syndicated posts,
1661 it (1) publishes them immediately, (2) turns comments off, and (3)
1662 turns trackback / pingback pings off. You can now alter all three
1663 default behaviors (e.g., to allow pings on syndicated posts, or to
1664 send newly-syndicated posts to the draft pile for moderation) using
1665 Options --> Syndication
1666
1667
1668 = From 0.91 to 0.95 =
1669
1670 * BUG FIX: Fixed an obscure bug in the handling of categories:
1671 categories with trailing whitespace could cause categories with
1672 duplicate names to be created. This no longer happens. While I was
1673 at it I tightened up the operation of
1674 FeedWordPress::lookup_categories() a bit in general.
1675
1676 * FEATURE DEPRECATED: the feed setting `hardcode categories` is now
1677 deprecated in favor of `unknown categories` (see below), which
1678 allows you to strip off any syndication categories not already in
1679 your database using `unknown categories: default` or `unknown
1680 categories: filter`. If you have `hardcode categories: yes` set on a
1681 feed, this will be treated as `unknown categories: default` (i.e.,
1682 no new categories will be added, but if a post doesn't match any of
1683 the categories it will be added in the default category--usually
1684 "Uncategorized" or "General").
1685
1686 * FEATURE: You can now set global defaults as to whether or not
1687 FeedWordPress will update the Link Name and Link Description
1688 settings for feeds automatically from the feed title and feed
1689 tagline. (By default, it does, as it has in past versions.) Whether
1690 this behavior is turned on or off, you can still override the
1691 default behavior using feed settings of `hardcode name: yes`,
1692 `hardcode name: no`, `hardcode description: yes`, or `hardcode
1693 description: no`.
1694
1695 * FEATURE: Users can now provide one or several "aliases" for an
1696 author, just as they can for a category. For example, to make
1697 FeedWordPress treat posts by "Joseph Cardinal Ratzinger" and "Pope
1698 Benedict XVI" as by the same author, edit the user profile for Pope
1699 Benedict XVI and add a line like this to the "User profile" field:
1700
1701 a.k.a.: Joseph Cardinal Ratzinger
1702
1703 You can add several aliases, each on a line by itself. You can also
1704 add any other text you like to the Profile without interfering with
1705 the aliases.
1706
1707 * FEATURE: Users can now choose how to handle syndicated posts that
1708 are in unfamiliar categories or by unfamiliar authors (i.e.,
1709 categories or authors whose names are not yet in the WordPress
1710 database). By default, FeedWordPress will (as before) create a new
1711 category (or new author) and use it for the current post and any
1712 future posts. This behavior can be changed, either for all feeds or
1713 for one or another particular feed.
1714
1715 There are now three different options for an unfamiliar author: (1)
1716 FeedWordPress can create a new author account and attribute the
1717 syndicated post to the new account; (2) FeedWordPress can attribute
1718 the post to an author if the author's name is familiar, and to a
1719 default author (currently, this means the Site Administrator
1720 account) if it is not; (3) FeedWordPress can drop posts by
1721 unfamiliar authors and syndicate only posts by authors who are
1722 already in the database.
1723
1724 There are, similarly, two different options for an unfamiliar
1725 category: (1) FeedWordPress can create new categories and place the
1726 syndicated post in them; (2) FeedWordPress can drop the unfamiliar
1727 categories and place syndicated posts only in categories that it is
1728 already familiar with. In addition, FeedWordPress 0.95 lets you
1729 choose whether posts that are in *no* familiar categories should be
1730 syndicated (and placed in the default category for the blog) or
1731 simply dropped.
1732
1733 You can set the default behavior for both authors and categories
1734 using the settings in Options --> Syndication. You can also set
1735 different behavior for specific feeds by adding the `unfamiliar
1736 author` and / or `unfamiliar categories` settings to the Link Notes
1737 section of a feed:
1738
1739 unfamiliar author: (create|default|filter)
1740 unfamiliar categories: (create|default|filter)
1741
1742 A setting of `unfamiliar author: create` will make FeedWordPress
1743 create new authors to match unfamiliar author names *for this feed
1744 alone*. A setting of `unfamiliar author: default` will make it
1745 assign posts from unfamiliar authors to the default user account. A
1746 setting of `unfamiliar author: filter` will cause all posts (from
1747 this feed alone) to be dropped unless they are by an author already
1748 listed in the database. Similiarly, `unfamiliar categories: create`
1749 will make FeedWordPress create new categories to match unfamiliar
1750 category names *for this feed alone*; `unfamiliar categories:
1751 default` will cause it to drop any unfamiliar category names; and
1752 `unfamiliar categories: filter` will cause it to *both* drop any
1753 unfamiliar category names *and* to only syndicate posts that are
1754 placed in one or more familiar categories.
1755
1756 These two new features allow users to do some coarse-grained
1757 filtering without having to write a PHP filter. Specifically, they
1758 offer an easy way for you to filter feeds by category or by author.
1759 Suppose, for example, that you only wanted to syndicate posts that
1760 your contributors place in the "Llamas" category. You could do so by
1761 setting up your installation of WordPress so that the only category
1762 in the database is "Llamas," and then use Options --> Syndication to
1763 set "Unfamiliar categories" to "don't create new categories and
1764 don't syndicate posts unless they match at least one familiar
1765 category". Now, when you update, only posts in the "Llamas" category
1766 will be syndicated by FeedWordPress.
1767
1768 Similarly, if you wanted to filter one particular feed so that only
1769 posts by (for example) the author "Earl J. Llama" were syndicated to
1770 your site, you could do so by creating a user account for Earl J.
1771 Llama, then adding the following line to the settings for the feed
1772 in Link Notes:
1773
1774 unfamiliar author: filter
1775
1776 This will cause any posts from this feed that are not authored by
1777 Earl J. Llama to be discarded, and only the posts by Earl J. Llama
1778 will be syndicated. (If the setting is used on one specific feed, it
1779 will not affect how posts from other feeds are syndicated.)
