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

170 MediaWiki 1.12 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
172 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
173 http://bugs.php.net/bug.php?id=34879
174 Upgrade affected systems to PHP 5.1 or higher.
176 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
177 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
182 1.12 has several database changes since 1.11, and will not work without schema
185 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
186 new database fields are filled with data.
188 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
189 changes are made, and there is a slightly higher chance that things could
190 break. Don't forget to always back up your database before upgrading!
192 See the file UPGRADE for more detailed upgrade instructions.
197 Some output, particularly involving user-supplied inline HTML, may not
198 produce 100% valid or well-formed XHTML output. Testers are welcome to
199 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
200 cases, but this is not recommended on live sites. (This must be set for
201 MathML to display properly in Mozilla.)

227 It's highly recommended that you sign up for one of these lists if you're
228 going to run a public MediaWiki, so you can be notified of security fixes.
