MediaWiki 1.14.0
February 22, 2009

This is the first stable release of the 2009 Q1 branch of MediaWiki.

MediaWiki is now using a "continuous integration" development model with quarterly snapshot releases. The latest development code is always kept "ready to run", and in fact runs our own sites on Wikipedia.

Release branches will continue to receive security updates for about a year from first release, but nonessential bugfixes and feature developments will be made on the development trunk and appear in the next quarterly release.

Those wishing to use the latest code instead of a branch release can obtain it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

NOTE: Installation of MediaWiki on SQLite has been temporarily disabled in this release due to the discovery of serious problems with the schema. We expect to fix this problem for the release of 1.15.0.

Compatibility
MediaWiki 1.14 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.

PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing: http://bugs.php.net/bug.php?id=34879 Upgrade affected systems to PHP 5.1 or higher.

MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.

Upgrading
1.14 has several database changes since 1.13, and will not work without schema updates.

If upgrading from before 1.11, and you are using a wiki as a commons reposito- ry, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

Caveats
Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.)

For notes on 1.13.x and older releases, see HISTORY.

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

Mailing list
A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list:

http://lists.wikimedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:

http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

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