   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

 128 regularly. Below only new and removed languages are listed, as well as
 129 changes to languages because of MediaZilla reports.
 130

 133
 134 * (bug 23156) Commafy and search normalization updated for Belarusian
 135   (Taraškievica)
 136
 137 == Compatibility ==
 138
 139 MediaWiki 1.17 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
 140 supported.
 141
 142 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 143 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 144
 145
 146 == Upgrading ==
 147
 148 1.17 has several database changes since 1.16, and will not work without schema
 149 updates.
 150
 151 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 152 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 153 database schema changes.
 154
 155 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 156 new database fields are filled with data.
 157
 158 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 159 changes are made, and there is a slightly higher chance that things could
 160 break. Don't forget to always back up your database before upgrading!
 161
 162 See the file UPGRADE for more detailed upgrade instructions.
 163
 164
 165 === Caveats ===
 166
 167 Some output, particularly involving user-supplied inline HTML, may not
 168 produce 100% valid or well-formed XHTML output. Testers are welcome to
 169 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 170 cases, but this is not recommended on live sites. (This must be set for
 171 MathML to display properly in Mozilla.)
 172

 176 === Online documentation ===

 189 wikitech-l list:
