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

493 == Compatibility ==
494
495 MediaWiki 1.13 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
496
497 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
498 http://bugs.php.net/bug.php?id=34879
499 Upgrade affected systems to PHP 5.1 or higher.
500
501 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
502 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
503
504
505 == Upgrading ==
506
507 1.13 has several database changes since 1.12, and will not work without schema
508 updates.
509
510 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
511 new database fields are filled with data.
512
513 If upgrading from before 1.11, and you are using a wiki as a commons repository,
514 make sure that it is updated as well. Otherwise, errors may arise due to
515 database schema changes.
516
517 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
518 changes are made, and there is a slightly higher chance that things could
519 break. Don't forget to always back up your database before upgrading!
520
521 See the file UPGRADE for more detailed upgrade instructions.

524 === Caveats ===
525
526 Some output, particularly involving user-supplied inline HTML, may not
527 produce 100% valid or well-formed XHTML output. Testers are welcome to
528 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
529 cases, but this is not recommended on live sites. (This must be set for
530 MathML to display properly in Mozilla.)
531
532 For notes on 1.12.x and older releases, see HISTORY.
533
534
535 === Online documentation ===
536
537 Documentation for both end-users and site administrators is currently being
538 built up on MediaWiki.org, and is covered under the GNU Free Documentation
539 License (except for pages that explicitly state that their contents are in
540 the public domain) :

543
544
545 === Mailing list ===
546
547 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
548 wikitech-l list:
549
550 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
551
552 A low-traffic announcements-only list is also available:
553
554 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
555
556 It's highly recommended that you sign up for one of these lists if you're
557 going to run a public MediaWiki, so you can be notified of security fixes.
558
559
560 === IRC help ===
561
562 There's usually someone online in #mediawiki on irc.freenode.net
