   6 == MediaWiki 1.13 ==
   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

 230 == Compatibility ==
 231
 232 MediaWiki 1.13 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 233
 234 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 235 http://bugs.php.net/bug.php?id=34879
 236 Upgrade affected systems to PHP 5.1 or higher.
 237
 238 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 239 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 240
 241
 242 == Upgrading ==
 243
 244 1.13 has several database changes since 1.12, and will not work without schema
 245 updates.
 246
 247 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 248 new database fields are filled with data.
 249
 250 If upgrading from before 1.11, and you are using a wiki as a commons repository,
 251 make sure that it is updated as well. Otherwise, errors may arise due to
 252 database schema changes.
 253
 254 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 255 changes are made, and there is a slightly higher chance that things could
 256 break. Don't forget to always back up your database before upgrading!
 257
 258 See the file UPGRADE for more detailed upgrade instructions.
 259
 260
 261 === Caveats ===
 262
 263 Some output, particularly involving user-supplied inline HTML, may not
 264 produce 100% valid or well-formed XHTML output. Testers are welcome to
 265 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 266 cases, but this is not recommended on live sites. (This must be set for
 267 MathML to display properly in Mozilla.)
 268
 269 For notes on 1.12.x and older releases, see HISTORY.
 270
 271
 272 === Online documentation ===
 273
 274 Documentation for both end-users and site administrators is currently being
 275 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 276 License (except for pages that explicitly state that their contents are in
 277 the public domain) :
 278
 279   http://www.mediawiki.org/wiki/Documentation
 280
 281
 282 === Mailing list ===
 283
 284 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 285 wikitech-l list:
 286
 287   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 288
 289 A low-traffic announcements-only list is also available:
 290
 291   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 292
 293 It's highly recommended that you sign up for one of these lists if you're
 294 going to run a public MediaWiki, so you can be notified of security fixes.
 295
 296
 297 === IRC help ===
 298
 299 There's usually someone online in #mediawiki on irc.freenode.net
