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.
10 This is a security and maintenance release.
12 MediaWiki is now using a "continuous integration" development model with
13 quarterly snapshot releases. The latest development code is always kept
14 "ready to run", and in fact runs our own sites on Wikipedia.
16 Release branches will continue to receive security updates for about a year
17 from first release, but nonessential bugfixes and feature developments
18 will be made on the development trunk and appear in the next quarterly release.
20 Those wishing to use the latest code instead of a branch release can obtain
21 it from source control: http://www.mediawiki.org/wiki/Download_from_SVN
23 == Changes since 1.15.4 ==

454 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
456 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
457 http://bugs.php.net/bug.php?id=34879
458 Upgrade affected systems to PHP 5.1 or higher.
460 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
461 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
466 1.15 has several database changes since 1.14, and will not work without schema
469 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
470 ry, make sure that it is updated as well. Otherwise, errors may arise due to
471 database schema changes.
473 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
474 new database fields are filled with data.
476 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
477 changes are made, and there is a slightly higher chance that things could
478 break. Don't forget to always back up your database before upgrading!
480 See the file UPGRADE for more detailed upgrade instructions.
485 Some output, particularly involving user-supplied inline HTML, may not
486 produce 100% valid or well-formed XHTML output. Testers are welcome to
487 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
488 cases, but this is not recommended on live sites. (This must be set for
489 MathML to display properly in Mozilla.)
