   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

 170 == Compatibility ==
 171
 172 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 173
 174 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 175 http://bugs.php.net/bug.php?id=34879
 176 Upgrade affected systems to PHP 5.1 or higher.
 177
 178 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 179 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 180
 181
 182 == Upgrading ==
 183
 184 1.12 has several database changes since 1.11, and will not work without schema
 185 updates.
 186
 187 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 188 new database fields are filled with data.
 189
 190 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 191 changes are made, and there is a slightly higher chance that things could
 192 break. Don't forget to always back up your database before upgrading!
 193
 194 See the file UPGRADE for more detailed upgrade instructions.
 195
 196
 197 === Caveats ===
 198
 199 Some output, particularly involving user-supplied inline HTML, may not
 200 produce 100% valid or well-formed XHTML output. Testers are welcome to
 201 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 202 cases, but this is not recommended on live sites. (This must be set for
 203 MathML to display properly in Mozilla.)
 204
 205 For notes on 1.11.x and older releases, see HISTORY.
 206
 207
 208 === Online documentation ===
 209
 210 Documentation for both end-users and site administrators is currently being
 211 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 212 License (except for pages that explicitly state that their contents are in
 213 the public domain) :

 216
 217
 218 === Mailing list ===
 219
 220 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 221 wikitech-l list:
 222
 223   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 224
 225 A low-traffic announcements-only list is also available:
 226
 227   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 228
 229 It's highly recommended that you sign up for one of these lists if you're
 230 going to run a public MediaWiki, so you can be notified of security fixes.
