   7
   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

 204 == Compatibility ==
 205
 206 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 207
 208 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 209 http://bugs.php.net/bug.php?id=34879
 210 Upgrade affected systems to PHP 5.1 or higher.
 211
 212 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 213 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 214
 215
 216 == Upgrading ==
 217
 218 1.12 has several database changes since 1.11, and will not work without schema
 219 updates.
 220
 221 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 222 new database fields are filled with data.
 223
 224 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 225 changes are made, and there is a slightly higher chance that things could
 226 break. Don't forget to always back up your database before upgrading!
 227
 228 See the file UPGRADE for more detailed upgrade instructions.
 229
 230
 231 === Caveats ===
 232
 233 Some output, particularly involving user-supplied inline HTML, may not
 234 produce 100% valid or well-formed XHTML output. Testers are welcome to
 235 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 236 cases, but this is not recommended on live sites. (This must be set for
 237 MathML to display properly in Mozilla.)
 238
 239 For notes on 1.11.x and older releases, see HISTORY.

 241
 242 === Online documentation ===
 243
 244 Documentation for both end-users and site administrators is currently being
 245 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 246 License (except for pages that explicitly state that their contents are in
 247 the public domain) :

 249   http://www.mediawiki.org/wiki/Documentation
 250
 251
 252 === Mailing list ===
 253
 254 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 255 wikitech-l list:
 256
 257   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 258
 259 A low-traffic announcements-only list is also available:
 260
 261   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 262
 263 It's highly recommended that you sign up for one of these lists if you're
 264 going to run a public MediaWiki, so you can be notified of security fixes.
 265
 266
 267 === IRC help ===
 268
 269 There's usually someone online in #mediawiki on irc.freenode.net
