   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.

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

 259 == Compatibility ==
 260
 261 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 262
 263 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 264 http://bugs.php.net/bug.php?id=34879
 265 Upgrade affected systems to PHP 5.1 or higher.
 266
 267 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 268 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 269
 270
 271 == Upgrading ==
 272
 273 1.12 has several database changes since 1.11, and will not work without schema
 274 updates.
 275
 276 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 277 new database fields are filled with data.
 278
 279 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 280 changes are made, and there is a slightly higher chance that things could
 281 break. Don't forget to always back up your database before upgrading!
 282
 283 See the file UPGRADE for more detailed upgrade instructions.
 284
 285
 286 === Caveats ===
 287
 288 Some output, particularly involving user-supplied inline HTML, may not
 289 produce 100% valid or well-formed XHTML output. Testers are welcome to
 290 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 291 cases, but this is not recommended on live sites. (This must be set for
 292 MathML to display properly in Mozilla.)
 293
 294 For notes on 1.11.x and older releases, see HISTORY.
 295
 296
 297 === Online documentation ===
 298
 299 Documentation for both end-users and site administrators is currently being
 300 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 301 License (except for pages that explicitly state that their contents are in
 302 the public domain) :

 304   http://www.mediawiki.org/wiki/Documentation
 305
 306
 307 === Mailing list ===
 308
 309 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 310 wikitech-l list:
 311
 312   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 313
 314 A low-traffic announcements-only list is also available:
 315
 316   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 317
 318 It's highly recommended that you sign up for one of these lists if you're
 319 going to run a public MediaWiki, so you can be notified of security fixes.
 320
 321
 322 === IRC help ===
 323
 324 There's usually someone online in #mediawiki on irc.freenode.net
