   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

 135 === Languages updated in 1.16 ===
 136
 137 MediaWiki supports over 300 languages. Many localisations are updated
 138 regularly. Below only new and removed languages are listed, as well as
 139 changes to languages because of MediaZilla reports.
 140

 142 * Add PLURAL function for Scots Gaelic (gd)
 143
 144 == Compatibility ==
 145
 146 MediaWiki 1.16 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
 147
 148 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 149 http://bugs.php.net/bug.php?id=34879
 150 Upgrade affected systems to PHP 5.1 or higher.
 151
 152 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 153 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 154
 155
 156 == Upgrading ==
 157
 158 1.16 has several database changes since 1.15, and will not work without schema
 159 updates.
 160
 161 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 162 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 163 database schema changes.
 164
 165 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 166 new database fields are filled with data.
 167
 168 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 169 changes are made, and there is a slightly higher chance that things could
 170 break. Don't forget to always back up your database before upgrading!
 171
 172 See the file UPGRADE for more detailed upgrade instructions.
 173
 174
 175 === Caveats ===
 176
 177 Some output, particularly involving user-supplied inline HTML, may not
 178 produce 100% valid or well-formed XHTML output. Testers are welcome to
 179 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 180 cases, but this is not recommended on live sites. (This must be set for
 181 MathML to display properly in Mozilla.)
 182
 183 For notes on 1.15.x and older releases, see HISTORY.

 185
 186 === Online documentation ===
 187
 188 Documentation for both end-users and site administrators is currently being
 189 built up on MediaWiki.org, and is covered under the GNU Free Documentation

 191 the public domain) :

 196 === Mailing list ===
 197
 198 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 199 wikitech-l list:

 202
 203 A low-traffic announcements-only list is also available:

 206
 207 It's highly recommended that you sign up for one of these lists if you're
 208 going to run a public MediaWiki, so you can be notified of security fixes.
