On Tuesday Steaphan Greene announced that all currently-pushed changes have now been rebased onto the newly-released upstream MySQL-5.6.24.

Not familiar with the WebScaleSQL project?
WebScaleSQL is a collaboration among engineers from several companies that face similar challenges in running MySQL at scale, and seek greater performance from a database technology tailored for their needs.
Who is behind WebScaleSQL?
WebScaleSQL currently includes contributions from MySQL engineering teams at Alibaba, Facebook, Google, LinkedIn, and Twitter. Together, we are working to share a common base of code changes to the upstream MySQL branch that we can all use and that will be made available via open source. This collaboration will expand on existing work by the MySQL community, and we will continue to track the upstream branch that is the latest, production-ready release (currently MySQL 5.6).
