   6 == MediaWiki 1.16 ==
   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

 170 == Compatibility ==
 171
 172 MediaWiki 1.16 requires PHP 5 (5.2 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 1.16 has several database changes since 1.15, and will not work without schema
 185 updates.
 186
 187 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 188 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 189 database schema changes.
 190
 191 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 192 new database fields are filled with data.
 193
 194 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 195 changes are made, and there is a slightly higher chance that things could
 196 break. Don't forget to always back up your database before upgrading!
 197
 198 See the file UPGRADE for more detailed upgrade instructions.
 199

 201 === Caveats ===
 202
 203 Some output, particularly involving user-supplied inline HTML, may not
 204 produce 100% valid or well-formed XHTML output. Testers are welcome to
 205 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 206 cases, but this is not recommended on live sites. (This must be set for
 207 MathML to display properly in Mozilla.)
 208
 209 For notes on 1.15.x and older releases, see HISTORY.

 211
 212 === Online documentation ===
 213
 214 Documentation for both end-users and site administrators is currently being
 215 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 216 License (except for pages that explicitly state that their contents are in
 217 the public domain) :

 220
 221
 222 === Mailing list ===
 223
 224 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 225 wikitech-l list:
 226
 227   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 228
 229 A low-traffic announcements-only list is also available:
 230
 231   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 232
 233 It's highly recommended that you sign up for one of these lists if you're
 234 going to run a public MediaWiki, so you can be notified of security fixes.
 235

 237 === IRC help ===
