   4 setting since version 1.2.0. If you have it on, turn it *off* if you can.

   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

 449 == Compatibility ==
 450
 451 MediaWiki 1.13 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 452
 453 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 454 http://bugs.php.net/bug.php?id=34879
 455 Upgrade affected systems to PHP 5.1 or higher.
 456
 457 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 458 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 459
 460
 461 == Upgrading ==
 462
 463 1.13 has several database changes since 1.12, and will not work without schema
 464 updates.
 465
 466 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 467 new database fields are filled with data.
 468
 469 If upgrading from before 1.11, and you are using a wiki as a commons repository,
 470 make sure that it is updated as well. Otherwise, errors may arise due to
 471 database schema changes.
 472
 473 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 474 changes are made, and there is a slightly higher chance that things could
 475 break. Don't forget to always back up your database before upgrading!
 476
 477 See the file UPGRADE for more detailed upgrade instructions.

 480 === Caveats ===
 481
 482 Some output, particularly involving user-supplied inline HTML, may not
 483 produce 100% valid or well-formed XHTML output. Testers are welcome to
 484 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 485 cases, but this is not recommended on live sites. (This must be set for
 486 MathML to display properly in Mozilla.)

 488 For notes on 1.12.x and older releases, see HISTORY.

 491 === Online documentation ===
 492
 493 Documentation for both end-users and site administrators is currently being
 494 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 495 License (except for pages that explicitly state that their contents are in
 496 the public domain) :

 501 === Mailing list ===
 502
 503 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 504 wikitech-l list:
 505
 506   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 507
 508 A low-traffic announcements-only list is also available:
 509
 510   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 511
 512 It's highly recommended that you sign up for one of these lists if you're
 513 going to run a public MediaWiki, so you can be notified of security fixes.
