MediaWiki 1.21

This is the version of MediaWiki currently on Wikimedia Foundation websites.

The Wikimedia Foundation deploys MediaWiki to its projects almost directly from the master branch through incremental "wmf"-branches within the 1.21 release cycle. The 1.21.0 stable tarball is expected to come out in the spring of 2013 (but one can also stay current on the bleeding-edge through git master).

Wikimedia deployments
MediaWiki 1.21 will include all changes released in the smaller, bi-weekly "1.21wmfX" software deployments to Wikimedia sites.

What's new?

 * ContentHandler: ...
 * Ajax patrolling, one of the features users have waited for longest: .... (bug 7851)

Internationalization:
 * We plan/hope to make the general logging framework completely localisable at last, by fixing bug 24156 (deferred since MediaWiki 1.18). The logging for each action (whether in core or extensions) might still need to be updated to use the new system, though.

Extensions:
 * No new extensions bundles have been decided for now, but we'd like to consider some: see Suggestions for extensions to be integrated.
