   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

 240 == Compatibility ==
 241
 242 MediaWiki 1.13 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 243
 244 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 245 http://bugs.php.net/bug.php?id=34879
 246 Upgrade affected systems to PHP 5.1 or higher.
 247
 248 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 249 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 250
 251
 252 == Upgrading ==
 253
 254 1.13 has several database changes since 1.12, and will not work without schema
 255 updates.
 256
 257 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 258 new database fields are filled with data.
 259
 260 If upgrading from before 1.11, and you are using a wiki as a commons repository,
 261 make sure that it is updated as well. Otherwise, errors may arise due to
 262 database schema changes.
 263
 264 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 265 changes are made, and there is a slightly higher chance that things could
 266 break. Don't forget to always back up your database before upgrading!
 267
 268 See the file UPGRADE for more detailed upgrade instructions.
 269
 270
 271 === Caveats ===
 272
 273 Some output, particularly involving user-supplied inline HTML, may not
 274 produce 100% valid or well-formed XHTML output. Testers are welcome to
 275 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 276 cases, but this is not recommended on live sites. (This must be set for
 277 MathML to display properly in Mozilla.)
 278
 279 For notes on 1.12.x and older releases, see HISTORY.
 280
 281
 282 === Online documentation ===
 283
 284 Documentation for both end-users and site administrators is currently being
 285 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 286 License (except for pages that explicitly state that their contents are in
 287 the public domain) :
 288
 289   http://www.mediawiki.org/wiki/Documentation
 290
 291
 292 === Mailing list ===
 293
 294 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 295 wikitech-l list:
 296
 297   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 298
 299 A low-traffic announcements-only list is also available:
 300
 301   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 302
 303 It's highly recommended that you sign up for one of these lists if you're
 304 going to run a public MediaWiki, so you can be notified of security fixes.
 305
 306
 307 === IRC help ===
 308
 309 There's usually someone online in #mediawiki on irc.freenode.net
