MediaWiki 1.21/wmf6

Deployment of MediaWiki 1.21wmf6 to Wikimedia sites

The latest version (labeled "1.21wmf6 ") of MediaWiki, the software that powers Wikipedia and its sister sites, is being deployed to all Wikimedia sites in stages, starting on Monday, 10 December 2012 (see the roadmap).

We will continue to deploy the latest software every two weeks. This is intended to minimize disruption and possible issues, and make it easier to identify the cause of problems, since the possibly problematic code will be much more recent.

Breaking changes

 * The message "wikimedia-editpage-tos-summary" (displayed below the edit form) has been removed, now "wikimedia-copyrightwarning" is needed; if you customised either of them, make sure that [ the original warning] and any additional custom text you need are on wikimedia-copyrightwarning.
 * E-mail notifications no longer say that a page was "created" for some actions like deletion or protection ; there are still some known issues. If you customised MediaWiki:Enotif body on your wiki, you have to delete or update it: the  variable is no longer provided, a new   is used; see also full documentation, and remember [//translatewiki.net/w/i.php?title=Special:Translate&task=view&group=core&limit=1000&offset=1000#msg_enotif_body to update translations on translatewiki.net].

Display changes

 * We changed the wording of the protectedpagetext message to include moving and other actions.
 * MediaWiki:Contributions now reflects the gender of the user.
 * We're displaying IPv6 addresses more nicely.

Fixes

 * Your "enhanced changelist" displays minor/bot changes better.

New

 * There's a new DynamicSidebar: tell us if your sidebar acts weird.
 * TimedMediaHandler now supports embedding a smaller audio player of 35-pixel width, and reorders the controls so that small players get a play/pause button and volume first.
 * In WebFonts we've added the Gubbit font, replacing Kedage, for Kannada.
