   3 Security reminder: MediaWiki does not require PHP's register_globals

   6 == MediaWiki 1.12 ==
   7
   8 THIS IS NOT A RELEASE YET
   9
  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.
  13
  14 Release branches will continue to receive security updates for about a year
  15 from first release, but nonessential bugfixes and feature developments
  16 will be made on the development trunk and appear in the next quarterly release.
  17
  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

  21 === Configuration changes in 1.12 ===
  22 * Marking edits as bot edits with Special:Contributions?bot=1 now requires the
  23   markbotedit permission, rather than the rollback permission previously used.
  24   This permission is assigned by default to the sysop group.
  25
  26 === New features in 1.12 ===
  27 * (bug 10735) Add a warning for non-descriptive filenames at Special:Upload
  28 * Add {{filepath:}} parser function to get full path to an uploaded file,
  29   complementing {{fullurl:}} for pages.
  30 * (bug 11136) If using Postgres, search path is explicitly set if wgDBmwschema is
  31   not set to 'mediawiki', allowing multiple mediawiki instances per user.
  32 * (bug 11151) Add descriptive <title> to revision history page
  33 * (bug 5412) Add feed links for the site to all pages
  34 * (bug 11353) Add ability to retrieve raw section content via action=raw
  35 * Show relevant deletion log lines when uploading a previously deleted file
  36 * On SkinTemplate based skins (like MonoBook), omit confusing "edit"/"view source"
  37   tab entirely if the page doesn't exist and the user isn't allowed to create it
  38 * Clarify instructions given when an exception is thrown
  39 * AuthPlugin added strictUserAuth() method to allow per-user override
  40   of the strict() authentication behavior.
  41 * (bug 7872) Deleted revisions can now be viewed as diffs showing changes
  42   against the previous revision, whether currently deleted or live.
  43 * Added tooltips for the "Go" and "Search" buttons
  44 * (bug 11649) Show input form when Special:Whatlinkshere has no parameters
  45 * isValidEmailAddr hook added to User method of that name, to allow, e.g., re-
  46   stricting e-mail addresses to a specific domain
  47 * Removed "Clear" link in watchlist editor tools, as people were afraid to
  48   click it. Existing clear links will fall back to the raw editor, which is
  49   very easy to clear your watchlist with.
  50 * (bug 1405) Add wgUseNPPatrol option to control patroling for new articles
  51   on Special:Newpages
  52 * LogLine hook added to allow formatting custom entries in Special:Log.

  57   globals have been set up but before any actions have been taken.
  58 * BeforeWatchlist hook added for filtering or replacing watchlist.
  59 * SkinTemplateTabAction hook added for altering the properties of tab links.
  60 * OutputPage::getRedirect public method added.
  61 * (bug 11848) Allow URL parameters 'editintro' and 'preload' in Special:Mypage
  62   and Special:Mytalk
  63 * Add ot=raw to Special:Allmessages
  64 * Support for Hebrew calendar
  65 * Support for Hebrew numerals in dates and times
  66 * (bug 11315) Signatures can be configured in [[MediaWiki:Signature]] and
  67   [[MediaWiki:Signature-anon]]
  68 * Signatures for anonymous users link to Special:Contributions page rather than user page
  69 * Added --override switch for disabled pages in updateSpecialPages.php
  70 * Provide a unique message (ipb_blocked_as_range) if unblock of a single IP fails
  71   because it is part of a blocked range.
  72 * (bug 3973) Use a separate message for the email content when an account is
  73   created by another user

 350 == Compatibility ==
 351
 352 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 353
 354 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 355 http://bugs.php.net/bug.php?id=34879
 356 Upgrade affected systems to PHP 5.1 or higher.
 357
 358 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 359 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 360
 361
 362 == Upgrading ==
 363
 364 1.12 has several database changes since 1.11, and will not work without schema
 365 updates.
 366
 367 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 368 new database fields are filled with data.
 369
 370 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 371 changes are made, and there is a slightly higher chance that things could
 372 break. Don't forget to always back up your database before upgrading!
 373
 374 See the file UPGRADE for more detailed upgrade instructions.
 375
 376
 377 === Caveats ===
 378
 379 Some output, particularly involving user-supplied inline HTML, may not
 380 produce 100% valid or well-formed XHTML output. Testers are welcome to
 381 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 382 cases, but this is not recommended on live sites. (This must be set for
 383 MathML to display properly in Mozilla.)
 384
 385 For notes on 1.11.x and older releases, see HISTORY.
 386
 387
 388 === Online documentation ===
 389
 390 Documentation for both end-users and site administrators is currently being
 391 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 392 License (except for pages that explicitly state that their contents are in
 393 the public domain) :
 394
 395   http://www.mediawiki.org/wiki/Documentation
 396
 397
 398 === Mailing list ===
 399
 400 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 401 wikitech-l list:
 402
 403   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 404
 405 A low-traffic announcements-only list is also available:
 406
 407   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 408
 409 It's highly recommended that you sign up for one of these lists if you're
 410 going to run a public MediaWiki, so you can be notified of security fixes.
 411
 412
 413 === IRC help ===
 414
 415 There's usually someone online in #mediawiki on irc.freenode.net
