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

432 == Compatibility ==
433
434 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
435
436 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
437 http://bugs.php.net/bug.php?id=34879
438 Upgrade affected systems to PHP 5.1 or higher.
439
440 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
441 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
442
443
444 == Upgrading ==
445
446 1.15 has several database changes since 1.14, and will not work without schema
447 updates.
448
449 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
450 ry, make sure that it is updated as well. Otherwise, errors may arise due to
451 database schema changes.
452
453 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
454 new database fields are filled with data.
455
456 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
457 changes are made, and there is a slightly higher chance that things could
458 break. Don't forget to always back up your database before upgrading!
459
460 See the file UPGRADE for more detailed upgrade instructions.
461
462
463 === Caveats ===
464
465 Some output, particularly involving user-supplied inline HTML, may not
466 produce 100% valid or well-formed XHTML output. Testers are welcome to
467 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
468 cases, but this is not recommended on live sites. (This must be set for
469 MathML to display properly in Mozilla.)

474 === Online documentation ===
475
476 Documentation for both end-users and site administrators is currently being
477 built up on MediaWiki.org, and is covered under the GNU Free Documentation
478 License (except for pages that explicitly state that their contents are in
479 the public domain) :

483
484 === Mailing list ===
485
486 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
487 wikitech-l list:
488
489 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
490
491 A low-traffic announcements-only list is also available:
492
493 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
494
495 It's highly recommended that you sign up for one of these lists if you're
496 going to run a public MediaWiki, so you can be notified of security fixes.
