   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

  46 === Languages updated in 1.18 ===
  47
  48 MediaWiki supports over 330 languages. Many localisations are updated
  49 regularly. Below only new and removed languages are listed, as well as
  50 changes to languages because of Bugzilla reports.
  51
  52 == Compatibility ==
  53
  54 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
  55 supported.
  56
  57 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
  58 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
  59
  60
  61 == Upgrading ==
  62
  63 1.18 has several database changes since 1.17, and will not work without schema
  64 updates.
  65
  66 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
  67 ry, make sure that it is updated as well. Otherwise, errors may arise due to
  68 database schema changes.
  69
  70 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  71 new database fields are filled with data.
  72
  73 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
  74 changes are made, and there is a slightly higher chance that things could
  75 break. Don't forget to always back up your database before upgrading!
  76
  77 See the file UPGRADE for more detailed upgrade instructions.

  80 === Caveats ===
  81
  82 Some output, particularly involving user-supplied inline HTML, may not
  83 produce 100% valid or well-formed XHTML output. Testers are welcome to
  84 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
  85 cases, but this is not recommended on live sites. (This must be set for
  86 MathML to display properly in Mozilla.)
  87
  88 For notes on 1.17.x and older releases, see HISTORY.

  91 === Online documentation ===

  94 built up on MediaWiki.org, and is covered under the GNU Free Documentation
  95 License (except for pages that explicitly state that their contents are in
  96 the public domain) :

 101 === Mailing list ===
 102
 103 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 104 wikitech-l list:
 105
 106         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 107
 108 A low-traffic announcements-only list is also available:
 109
 110         http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 111
 112 It's highly recommended that you sign up for one of these lists if you're
 113 going to run a public MediaWiki, so you can be notified of security fixes.
