VisualEditor was updated as part of the wider MediaWiki 1.21wmf12 branch deployment on Monday 18 March. In the two weeks since 1.21wmf11, the team have worked on building infrastructure for the new features that we are adding for VisualEditor's wider launch as the default way users will edit wikis.

In the way that the code integrates with MediaWiki, the save button now will be disabled if a user makes changes and then undoes all of them (42939). When an error happens with the Parsoid server, those errors are split out so that the user can report what broke in a way that we can trouble-shoot their issue (44354). When the Parsoid server is not responding, the code supplies a better error message for users (45916).

When selections are auto-expanded to the current context (when a user double-clicks on a word), we now better cover the concept of a 'word boundary', working towards Unicode's definition (44085). Lists now don't get corrupted for Parsoid when "unlist"ing their contents, removing their 'generated' property (45590).

Leaving the link inspector no longer clears a link accidentally (46025). The document model layer now presents categories (and other kinds of meta-content, like language links) for editing to other parts of the code base ahead of supporting user editing of categories in VisualEditor (39597), which is one of the four major features planned before wider launch.

A complete list of individual code commits is available in the 1.21/wmf12 changelog, and all Bugzilla bugs closed in this period on Bugzilla's list.
