   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

 390 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 391 http://bugs.php.net/bug.php?id=34879
 392 Upgrade affected systems to PHP 5.1 or higher.
 393
 394 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 395 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.

 398 == Upgrading ==
 399
 400 1.15 has several database changes since 1.14, and will not work without schema
 401 updates.
 402
 403 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 404 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 405 database schema changes.
 406
 407 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 408 new database fields are filled with data.
 409
 410 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 411 changes are made, and there is a slightly higher chance that things could
 412 break. Don't forget to always back up your database before upgrading!
 413
 414 See the file UPGRADE for more detailed upgrade instructions.

 417 === Caveats ===
 418
 419 Some output, particularly involving user-supplied inline HTML, may not
 420 produce 100% valid or well-formed XHTML output. Testers are welcome to
 421 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 422 cases, but this is not recommended on live sites. (This must be set for
 423 MathML to display properly in Mozilla.)

 425 For notes on 1.14.x and older releases, see HISTORY.

 428 === Online documentation ===
 429
 430 Documentation for both end-users and site administrators is currently being
 431 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 432 License (except for pages that explicitly state that their contents are in
 433 the public domain) :

 437
 438 === Mailing list ===
 439
 440 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 441 wikitech-l list:
 442
 443   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 444
 445 A low-traffic announcements-only list is also available:
 446
 447   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 448
 449 It's highly recommended that you sign up for one of these lists if you're
 450 going to run a public MediaWiki, so you can be notified of security fixes.
