   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

 201
 202 == Compatibility ==
 203
 204 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
 205
 206 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 207 http://bugs.php.net/bug.php?id=34879
 208 Upgrade affected systems to PHP 5.1 or higher.
 209
 210 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 211 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 212
 213
 214 == Upgrading ==
 215
 216 1.15 has several database changes since 1.14, and will not work without schema
 217 updates.
 218
 219 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 220 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 221 database schema changes.
 222
 223 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 224 new database fields are filled with data.
 225
 226 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 227 changes are made, and there is a slightly higher chance that things could
 228 break. Don't forget to always back up your database before upgrading!
 229
 230 See the file UPGRADE for more detailed upgrade instructions.
 231
 232
 233 === Caveats ===
 234
 235 Some output, particularly involving user-supplied inline HTML, may not
 236 produce 100% valid or well-formed XHTML output. Testers are welcome to
 237 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 238 cases, but this is not recommended on live sites. (This must be set for
 239 MathML to display properly in Mozilla.)
 240

 243
 244 === Online documentation ===
 245
 246 Documentation for both end-users and site administrators is currently being
 247 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 248 License (except for pages that explicitly state that their contents are in
 249 the public domain) :

 252
 253
 254 === Mailing list ===
 255
 256 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 257 wikitech-l list:
 258
 259   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 260
 261 A low-traffic announcements-only list is also available:
 262
 263   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 264
 265 It's highly recommended that you sign up for one of these lists if you're
 266 going to run a public MediaWiki, so you can be notified of security fixes.
