MediaWiki 1.22

MediaWiki 1.22 is currently being developed. Consult the RELEASE-NOTES file for the full list of changes. It is currently deployed on Wikimedia Foundation wikis through incremental "wmf"-branches starting April 2013. The 1.22.0 stable release is expected to come out late in 2013. Download the or checkout the   branch in Git to follow this release.

More anti-vandalism improvements
After MediaWiki 1.21 new core features and bundled anti-spam extensions, 1.22 will continue the job:
 * The patrolling system has been changed so that the link to mark a page or revision as patrolled is always shown when the revision or page is patrollable. This also removed the usage of the rcid URI parameters.
 * SimpleAntiSpam will be bundled (it's a little but harmless help against the simplest forms of spambots).
 * Global blocking API added.

Several ancient skins removed


On 2013-04-01, several ancient skins were removed from core (not an April's fool joke): Chick, Classic, MySkin, Nostalgia and Simple. More information at Turning off outdated skins.

Nostalgia was the phase I/UseModWiki-like skin, and Classic was the main skin before the introduction of the default MonoBook in MediaWiki 1.3 (2004-05-22). Dating back to February 2002, both skins existed over a year before MediaWiki got its name.

Blank system messages must be deleted
(Add ability to disable MediaWiki messages) was fixed: now blanking a system message (editing it on wiki to remove all content) will no longer restore the default value for the message, but instead make it show as empty string in the interface. If you have blank messages on your wiki (check Special:AllMessages), you must delete them.

What's new?
MediaWiki 1.22 will include all changes released in the smaller "1.22wmfX" software deployments to Wikimedia sites.
