1 = MediaWiki release notes =
3 Security reminder: MediaWiki does not require PHP's register_globals
4 setting since version 1.2.0. If you have it on, turn it *off* if you can.
8 THIS IS NOT A RELEASE YET.
10 MediaWiki is now using a "continuous integration" development model with
11 quarterly snapshot releases. The latest development code is always kept
12 "ready to run", and in fact runs our own sites on Wikipedia.
14 Release branches will continue to receive security updates for about a year
15 from first release, but nonessential bugfixes and feature development happen
16 will be made on the development trunk and appear in the next quarterly release.
18 Those wishing to use the latest code instead of a branch release can obtain
19 it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

136 * Various fixes related to the blocking change re: autoblocks. On inserting
137 an IP block, the ipb_enable_autoblock field is now automagically blanked,
138 because it doesn't make any sense for an IP. Additionally, IP blocks
139 without the ipb_enable_autoblock option no longer show up as "autoblock
140 disabled" on Special:Ipblocklist.

162 with compression or legacy encoding
163 * (bug 6737) Fixes for MySQL 5 schema in strict mode

165 into the HTML output.
166 * Make the DNSBL to check for proxy blocking configurable via $wgSorbsUrl
167 * Add experimental recording/reporting mode to parser tests runner, to

170 source this and pass --record option to parserTests.php
171 * Make the set of default parser test input files extensible via
172 $wgParserTestFiles. This can now be appended to by extensions or local

174 run along with the main batch.
175 * Run PHP install version checks on update.php so command-line updaters see
176 new version requirements
177 * Do a check for the PHP 5.0.x 64-bit bug, since this is much more disruptive
178 as of MW 1.8 than it used to be. Install or upgrade now aborts with a
179 warning and a request to upgrade.
180 * (bug 6440) Updated indexes to improve backlinking queries (links, templates, images)
181 * Switched 'anon-only' block mode to default for IP blocks

197 and user JS subpages.
198 * (bug 7918) "Templates used on this page" changes during preview to reflect
199 any added or removed templates, and works as expected for section edits.
200 * (bug 7919) "Templates used on this page" is now shown for read-only pages.
201 * (bug 7688) When viewing diff, section anchors in autosummary jump to section
202 on current page instead of loading the latest version.
203 * (bug 7970) Use current connection explicitly on Database::getServerVersion
204 * (bug 2001) Tables with class="sortable" can now be dynamically sorted via
206 * Added autosummary for new pages with 500 or less characters, and refactor
207 the autosummary code so it's all done in one function. doEdit is getting too
209 * (bug 7554) The correct MIME type for SVG images is now displayed on the
210 image page (image/svg+xml, not image/svg).
211 * (bug 7883) Added autoblock whitelisting feature, using which specific ranges

215 * (bug 8009) Automatic edit summary for redirects is not filled for edits in existing pages
216 * Installer support for experimental MySQL 4.1/5.0 binary-safe schema

219 * Add a hook 'UploadForm:initial' before the upload form is generated, and two
220 member variable for text injection into the form, which can be filled by the hooks.
221 * (bug 6295) Add a "revision patching" functionality, where an edit can be undone
222 (with a functionality similar to diff rev1 rev2 | patch -R rev3 -o rev3).
223 This is triggered by including &undo=revid in an edit URL. A link to a URL
224 that will undo a given edit is shown on NEW NON-CURRENT revision headers on diff pages.
225 * Fix display of link in "already rolled back" message for image/category pages
226 * (bug 6016) Left-aligned images should stack vertically, like right-aligned
227 images, not horizontally.

229 * Add AuthPluginSetup hook to override $wgAuth after configuration
230 * Fix regression in authentication hook auto-creation on login

233 * Added 'EditPage::attemptSave' hook before an article is saved.
234 * (bug 8083) Applied patch for sk localisation
235 * Add a backslash character to the edit token, to prevent edits via certain
236 broken proxies that mangle such characters in form submissions
237 * (bug 7461) Allow overwriting pages using importTextFile.php
238 * (bug 7946) importTextFile.php doesn't perform pre-save transform
239 * (bug 8117) {{REVISIONTIMESTAMP}} showed weird default if $wgLocalTZoffset set;
240 now uses current time for previews and if timestamp can't be loaded from DB
241 * {{REVISIONTIMESTAMP}} now uses site local timezone instead of user timezone
242 to ensure consistent behavior
243 * {{REVISIONTIMESTAMP}} and friends should now work on non-MySQL backends
244 * (bug 7671) Observe canonical media namespace prefix in Linker::formatComment
245 * Added js variable wgCurRevisionId to the output
246 * (bug 8141) Cleanup of Parser::doTableStuff, patch by AzaTht
247 * (bug 8042) Make miser mode caching limits settable via $wgQueryCacheLimit
248 instead of hardcoding to 1000
249 * Enable QueryPage classes to override list formatting
250 * (bug 5485) Show number of intervening revisions in diff view
251 * (bug 8100) Fix XHTML validity in Taiwanese localization
252 * Added redirect to section feature. Use it wisely.
253 * Added a configuration variable allowing the "break out of framesets" feature
254 to be switched on and off ($wgBreakFrames). Off by default.
255 * Allow Xml::check() $attribs parameter to override 'value' attribute
256 * DB schema change: added two columns (rc_old_len and rc_new_len) to the recentchanges table to store
257 the text lengths before and after the edit
258 * (bug 1085) Made Special:Recentchanges show the character difference between the changed revisions
259 * Removed a redundant <strong> tag from diff pages that was causing display issues for some users
260 * (bug 8203) The keyboard shortcut for "log out" was removed, because users were pressing it
261 when they intended to press the shortcut for "preview".
262 * (bug 8148) Handle non-removable output buffers gracefully when cleaning
263 buffers for HTTP 304 responses, StreamFile, and Special:Export.
264 Duplicated code merged into wfResetOutputBuffers() and wfClearOutputBuffers()
265 * Special:AllPages : 'next page' link now point to the first title of the next
266 chunk instead of pointing to the last title of current chunk.
267 * (bug 4673) Special:AllPages : add a 'previous' link (new message 'prevpage')
268 * (bug 8121) wfRandom() was not between 0 and 1
269 * Add static method Parser::createAssocArgs($args), so parser functions can
270 use the same code to parse arguments as the templates do.
271 * Change behavior of logins using the temporary e-mailed password (as stored
272 in user_newpassword hash field). Instead of just logging in silently and
273 leaving the previous user_password field in place indefinitely, the user
274 is now prompted to set a new password.
276 The password-changing form is at Special:Resetpass; currently it's only
277 usable for changing from the temporary password during login, but it
278 could perhaps be generalized, replacing the subform in preferences.
280 Once the new password is set successfully, the temporary password is wiped
281 so it cannot be used to login a second time, and the login process
283 * Suppress 'mail new password' button on login form if $wgAuth forbids
284 changing user passwords; it wouldn't work very well...
285 * Consolidate password length checks and $wgAuth manipulation into
286 User::setPassword() to avoid duplicate code in different places
288 * User::setPassword() now throws PasswordError exceptions if the password
289 is illegal or cannot be set via $wgAuth. These can be caught and a human-
290 readable error message displayed by UI code.
291 * Added Title::isSubpage()
292 * (bug 8241) Don't consider user pages of User:Foo.css to be CSS subpages
293 * Set an explicit class on framed thumbnail inner divs and images, changed some
294 CSS to use these instead of using descendent selectors.
295 * Accept null parameter to User::setPassword() as indicating the password
296 field should be cleared to an unusable state. Login will only be possible
297 after the password is reset, for instance by e-mail.
298 * (bug 6394) Invalidate the password set for "by e-mail" account creations
299 to avoid accidental empty password creations.
300 * Made the show change size function work on page moves, page creations, and
301 log entries. Also fixed it in the javascript recentchanges.
302 * (bug 8239) correctly get 50 new contributions when clicking '(50 next)'
303 * (bug 2259) Fix old regression where e-mail addresses were no longer
304 confirmed on login with mailed password.
305 * Add a notification about the confirmation mail sent during account
306 creation, so people don't immediately go off to request a second one.
307 * Add a warning on Special:Confirmemail if a code was already sent and has
309 * Add user_editcount field to provide data for heuristics on account use.
310 Incremented on edit, with lazy initialization from past revision data.
311 Can batch-initialize with maintenance/initEditCount.php (not yet friendly
312 to replication environments, this will do all accounts in one query).
313 * Allow raw SQL subsections in Database::update() SET portion as well as
314 for WHERE portion. Handy for increments and such.
315 * User::getOption now accept a default value to override default user values
316 this makes it consistent with WebRequest::get* methods. Corrected code in
317 various places accordingly.
318 * (bug 8264) Fix JavaScript global vars for XHTML mode
319 * Make $wgSiteNotice value wikitext again, for consistency with editable
320 MediaWiki:Sitenotice and MediaWiki:Anonnotice.
321 * (bug 8044) When redirecting from the canonical name of the special page
322 to the localised one, parameters/subpages are omitted
323 * (bug 8164) Special:Booksources should use GET for form submission
324 * Rewrite Special:Booksources to clean up interface and remove redundant code
325 * (bug 7925) Change Special:Allmessages message name filter javascript to be
326 a bit more responsive and easier on the CPU
327 * (bug 4488) Support watching pages on deletion; introduces new user preference
328 * Minor restructuring of Special:Preferences; "watch pages I edit" and "watch
329 pages I create" options now accessible under "Watchlist" options
330 * (bug 8153) <nowiki> doesn't work in site notice
331 * (bug 6690) wfMsgNoTrans() transforms messages
332 * (bug 8274) Wrap edit tools in a <div> with a specified class
333 * Detect PHP 5.0.x 64-bit bug and abort in WebStart.php; too many things break
334 mysteriously otherwise (detection code copied from install-utils.inc)
335 * (bug 8295) Change handling of <center> tags in doBlockLevels() to match that
337 * (bug 8110) Make magic ISBN linking stricter: only match ten-digit sequences
338 (plus optional ISBN-13 prefix) with no immediately following alphanumeric
339 character, disallow multiple consecutive internal redirects
340 * (bug 2785) Accept optional colon prefix in links when formatting comments
341 * Don't show "you can view and copy the source of this page" message for
342 pages which don't exist
343 * (bug 8310) Blank line added to top of 'post' when page is blank
344 * (bug 8109) Template parameters ignored in "recentchangestext"
345 * Gracefully skip redirect-to-fragment on WebKit versions less than 420;
346 it messes up on current versions of Safari but is ok in the latest
347 nightlies. Checking the version number will allow it to automatically
348 work when new releases of Safari appear.
349 * Fix regression in thumb styles; size and padding didn't match with
351 * (bug 8333) Fix quick user data update on login password change on
352 replication database setups. User data is now pulled from master
353 instead of slave in User::loadFromDatabase, ensuring that it is
354 fresh and accurate when read and then saved back into cache.
355 This was breaking with the Special:Rename operation which
356 automatically logs the user in with the new password after changing
357 it; pulling from slave meant the record was often not the updated
359 * (bug 8335) Set image width to the first valid parameter found.
360 * (bug 8350) Fix watchlist viewing bug when using Postgres.
361 * (bug 6603) When warning about invalid file extensions, output the bit
362 of the extension we actually checked
363 * (bug 7669) Drop defaults on BLOB/TEXT columns for better compatibility
364 with MySQL's strict mode, often enabled by the Windows installer.
365 The defaults are ignored anyway when strict mode is off...
366 * (bug 7685) Use explicit values for ar_text and ar_flags when deleting,
367 for better compatibility with MySQL's strict mode
368 * Update default interwiki values to reflect changed location of ursine:
369 * (bug 5411) Remove autopatrol preference
370 * Users who have the "autopatrol" permission will have their edits marked as
371 patrolled automatically
372 * Users who do not have the "autopatrol" permission will no longer be able
373 to mark their own edits as patrolled
374 * Introduce 'PingLimiter' hook; see docs/hooks.txt for more information
375 * (bug 532) Tweaked alt text for some interface messages
376 * (bug 8231) Gave useful alt text to the main <img> on image pages
377 * (bug 371) Remove alt text for "Enlarge" icon on thumbnails
378 * Initialize user_editcount to 0 instead of NULL for newly created accounts
379 * (bug 3696) Strip LRM and RLM characters from titles to work around the
380 problem some people have where titles cut-and-pasted from lists include
381 the bidi override characters appended to the lists.
382 A more thorough blacklist for forbidden and translatable characters would
383 be wise, though, as might a cleaner method for the lists in the first place.
384 * Fix regression in email password resets on read-restricted sites
385 * Set tabindex on fields in deletion form so you don't have to tab through
386 the links in the sitenotice
387 * (bug 8271) Show full time and date on viewer for individual deleted
389 * (bug 8214) Output file size limit and actual file size in appropriate units
391 * (bug 8016) Purge objectcache table during upgrade processes - use the --nopurge
392 option to prevent this when running maintenance/update.php
393 * (bug 7612) Remove superfluous link to Special:Categories from result items
394 on Special:Mostcategories
395 * {{PLURAL:}} now handles formatted numbers correctly
396 * (bug 8331) Added the change size value to watchlists; therefore made
397 watchlists use RecentChange::newFromRow() instead of newFromCurRow()
398 * (bug 8351) Fix undo for simple reverts
399 * (bug 6856) User::clearNotification() does not respect read-only mode
400 * (bug 6853) Use a checkbox on the installer form to indicate that a superuser
401 account should be used; this is clearer than the old check which relied on
402 the password never being an obscure value
403 * Remove old unused watchlist cache, which was a leftover from the old schema
404 where watchlists were more expensive to generate
405 * Minor cosmetic changes to Special:Userrights
406 * Added wgCanonicalSpecialPageName to JavaScript variables
407 * Fix image deleting when using Postgres.
408 * Output both source and destination titles in maintenance/moveBatch.php
409 * Added basic parser tests for language variants
410 * Enable selflinks and categories to be written in some of the language variants
411 * Prevent conversion of JavaScript code in language variants
412 * Output software version number in maintenance/parserTests.php
413 * (bug 7169) Use Ajax to watch/unwatch articles if enabled
414 * Make variant table caching a little more robust, using main language code
415 in cache key. Probably this is still a bit wonky, though. Was breaking

501 MediaWiki 1.9 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
503 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
504 http://bugs.php.net/bug.php?id=34879
505 Upgrade affected systems to PHP 5.1 or higher.
507 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
508 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
513 Some minor database changes have been made since 1.7:
514 * new fields and indexes on ipblocks
515 * index change on recentchanges
517 Several changes from 1.5 and 1.6 do require updates to be run on upgrade.
518 To ensure that these tables are filled with data, run refreshLinks.php after
521 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
522 changes are made, and there is a slightly higher chance that things could
523 break. Don't forget to always back up your database before upgrading!
525 See the file UPGRADE for more detailed upgrade instructions.
531 Some output, particularly involving user-supplied inline HTML, may not
532 produce 100% valid or well-formed XHTML output. Testers are welcome to
533 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
534 cases, but this is not recommended on live sites. (This must be set for
535 MathML to display properly in Mozilla.)

543 Documentation for both end-users and site administrators is currently being
544 built up on Meta-Wikipedia, and is covered under the GNU Free Documentation
547 http://www.mediawiki.org/wiki/Documentation
552 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
555 http://mail.wikimedia.org/mailman/listinfo/mediawiki-l
557 A low-traffic announcements-only list is also available:
559 http://mail.wikimedia.org/mailman/listinfo/mediawiki-announce
561 It's highly recommended that you sign up for one of these lists if you're
562 going to run a public MediaWiki, so you can be notified of security fixes.
