1 = MediaWiki release notes =
3 Security reminder: MediaWiki does not require PHP's register_globals
4 setting since version 1.2.0. If you have it on, turn it *off* if you can.
8 THIS IS NOT A RELEASE YET
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.
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.
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

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