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

367 MediaWiki 1.15 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.
369 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
370 http://bugs.php.net/bug.php?id=34879
371 Upgrade affected systems to PHP 5.1 or higher.
373 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
374 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
379 1.15 has several database changes since 1.14, and will not work without schema
382 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
383 ry, make sure that it is updated as well. Otherwise, errors may arise due to
384 database schema changes.
386 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
387 new database fields are filled with data.
389 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
390 changes are made, and there is a slightly higher chance that things could
391 break. Don't forget to always back up your database before upgrading!
393 See the file UPGRADE for more detailed upgrade instructions.
398 Some output, particularly involving user-supplied inline HTML, may not
399 produce 100% valid or well-formed XHTML output. Testers are welcome to
400 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
401 cases, but this is not recommended on live sites. (This must be set for
402 MathML to display properly in Mozilla.)
404 For notes on 1.14.x and older releases, see HISTORY.
