   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

 146

 152
 153 == Compatibility ==
 154
 155 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
 156
 157 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 158 http://bugs.php.net/bug.php?id=34879
 159 Upgrade affected systems to PHP 5.1 or higher.
 160
 161 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 162 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 163
 164
 165 == Upgrading ==
 166
 167 1.15 has several database changes since 1.14, and will not work without schema
 168 updates.
 169
 170 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 171 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 172 database schema changes.
 173
 174 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 175 new database fields are filled with data.
 176
 177 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 178 changes are made, and there is a slightly higher chance that things could
 179 break. Don't forget to always back up your database before upgrading!
 180
 181 See the file UPGRADE for more detailed upgrade instructions.
 182
 183
 184 === Caveats ===
 185
 186 Some output, particularly involving user-supplied inline HTML, may not
 187 produce 100% valid or well-formed XHTML output. Testers are welcome to
 188 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 189 cases, but this is not recommended on live sites. (This must be set for
 190 MathML to display properly in Mozilla.)
 191
 192 For notes on 1.14.x and older releases, see HISTORY.

 195 === Online documentation ===
 196

 205 === Mailing list ===
 206
 207 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 208 wikitech-l list:

 215
 216 It's highly recommended that you sign up for one of these lists if you're
 217 going to run a public MediaWiki, so you can be notified of security fixes.
