   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

  36
  37 == Compatibility ==
  38
  39 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
  40
  41 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
  42 http://bugs.php.net/bug.php?id=34879
  43 Upgrade affected systems to PHP 5.1 or higher.
  44
  45 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
  46 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
  47
  48
  49 == Upgrading ==
  50
  51 1.12 has several database changes since 1.10, and will not work without schema
  52 updates.
  53
  54 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  55 new database fields are filled with data.
  56
  57 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
  58 changes are made, and there is a slightly higher chance that things could
  59 break. Don't forget to always back up your database before upgrading!
  60
  61 See the file UPGRADE for more detailed upgrade instructions.
  62
  63
  64 === Caveats ===
  65
  66 Some output, particularly involving user-supplied inline HTML, may not
  67 produce 100% valid or well-formed XHTML output. Testers are welcome to
  68 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
  69 cases, but this is not recommended on live sites. (This must be set for
  70 MathML to display properly in Mozilla.)
  71
  72 For notes on 1.11.x and older releases, see HISTORY.

  75 === Online documentation ===
  76
  77 Documentation for both end-users and site administrators is currently being
  78 built up on MediaWiki.org, and is covered under the GNU Free Documentation
  79 License (except for pages that explicitly state that their contents are in
  80 the public domain) :

  85 === Mailing list ===
  86
  87 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
  88 wikitech-l list:
  89
  90   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
  91
  92 A low-traffic announcements-only list is also available:

  94   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
  95
  96 It's highly recommended that you sign up for one of these lists if you're
  97 going to run a public MediaWiki, so you can be notified of security fixes.
