   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

 103
 104 == Compatibility ==
 105
 106 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
 107
 108 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 109 http://bugs.php.net/bug.php?id=34879
 110 Upgrade affected systems to PHP 5.1 or higher.
 111
 112 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 113 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 114
 115
 116 == Upgrading ==
 117
 118 1.15 has several database changes since 1.14, and will not work without schema
 119 updates.
 120
 121 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 122 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 123 database schema changes.
 124
 125 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 126 new database fields are filled with data.
 127
 128 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 129 changes are made, and there is a slightly higher chance that things could
 130 break. Don't forget to always back up your database before upgrading!
 131
 132 See the file UPGRADE for more detailed upgrade instructions.
 133
 134
 135 === Caveats ===
 136
 137 Some output, particularly involving user-supplied inline HTML, may not
 138 produce 100% valid or well-formed XHTML output. Testers are welcome to
 139 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 140 cases, but this is not recommended on live sites. (This must be set for
 141 MathML to display properly in Mozilla.)
 142
 143 For notes on 1.14.x and older releases, see HISTORY.
 144
 145
 146 === Online documentation ===
 147
 148 Documentation for both end-users and site administrators is currently being
 149 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 150 License (except for pages that explicitly state that their contents are in
 151 the public domain) :

 154
 155
 156 === Mailing list ===
 157
 158 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 159 wikitech-l list:
 160
 161   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 162
 163 A low-traffic announcements-only list is also available:
 164
 165   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 166
 167 It's highly recommended that you sign up for one of these lists if you're
 168 going to run a public MediaWiki, so you can be notified of security fixes.
