Apologies for sending two at once - I failed to do this for the late-October one when the focus was on the monthly update:
The VisualEditor was updated as part of the wider MediaWiki 1.21wmf3 branch deployment on Monday 29 October.
In two weeks since 1.21wmf2, the team have continued to devote most of their time working on re-designing how the code integrates together and providing clean interfaces between them so new developers can re-use and extend VisualEditor in the future.
A complete list of individual code commits is available in the 1.21/wmf3 changelog, and all Bugzilla bugs closed in this period on Bugzilla's list.
The VisualEditor was updated as part of the wider MediaWiki 1.21wmf4 branch deployment on Monday 12 November.
In two weeks since 1.21wmf3, the team have spent their time mostly working on finalising the code in preparation for its deployment in December as a test for users. One of the major changes to the integration code is how the VisualEditor can be used; it now can work on other pages than just those in the VisualEditor: namespace. (This is configurable on a per-wiki basis, rather than defined in the code itself.) Amongst other things, this now means that editing the wikitext of VisualEditor: namespace pages can be done by anyone, and is no longer restricted to just sysops (as will be needed for the December deployment). The related bugs surrounding permission checks, filter checks, conflicts, etc. remain, and will be fixed in the next release.
Part of the preparations involved entirely re-writing the user interface code including the way in which commands operate (40896). Another aspect was the addition of "Change Markers" to the data sent to theParsoid system to reduce any accidental changes that should not happen when users save. Finally, a bug with how the "save page" button worked on old revisions was fixed (41865).
A complete list of individual code commits is available in the 1.21/wmf4 changelog, and all Bugzilla bugs closed in this period on Bugzilla's list.
An update for the Parsoid is available on its status page.
