In December, the latest and greatest version of MediaWiki was released, 1.22. This was lead by Mark Hershberger and Markus Glaser, working as the MediaWiki release team, along with help from the Wikimedia Foundation Release and QA team (specifically Greg Grossmeier and Antoine Musso). Of course, this was only possible because of the great work by all of the MediaWiki developers.

The QA team, along with Multimedia team, is working on API level tests starting with UploadWizard. This is close to being done. Another API level testing activity is Parsoid, with help from VE and CI (Antoine) teams.

You can take a look at the first draft of the updated Development and Deployment process flow chart.

 The Release and QA team had their latest quarterly review on February 13. Highlights from the meeting include: Notable progress on things with visuals includes an updated Development and deployment flowchart (opposite), as well as an auto-generated version.
 * We will be hiring two new positions (a QA Automation Engineer and a Test Infrastructure Engineer).
 * We will process through all pain points from the Development and Deployment process review.
 * We will continue performing incremental improvements to the current deployment script (known as "scap") to better inform future deployment tooling work.
 * We will create a way for tests to create fake/stub data (for use in throw-away/one-off test instances).
 * We will make it so our browser tests are more accurate cross testing and production environments.

The Beta Cluster has been migrated from the Tampa data center to the Ashburn data center. In the move, a ton of cleanup and Puppetization work was done. This will make future Beta Cluster work easier. In addition, the Beta Cluster is getting closer to a place where we can test our current main deployment tool known as "scap" along with future/other deployment tools.

The team continued on the rewrite of scap into python (from Bash scripts + PHP), improving both performance and maintainability in addition to being in a better position to move to a new tool in the future. We have also started doing SWAT deploy windows twice a day (Monday to Thursday) which has greatly increased momentum for many developers who would otherwise have to wait until the weekly deployment cycle.
