Wayland 1.0 was released last month but the code for it and Weston were still living on master. Following the release, 1.0 was still on master to get developers to focus on any bug-fixes before moving ahead with new features and improvements for the next major release. After a couple of weeks, it's now time to move the 1.0 code-bases of Wayland and Weston into a branch so that Git master can move ahead.
With the branching having occurred on Friday, Kristian already went ahead and pushed the Raspberry Pi back-end, new debug key-bindings, improved full-screen support for compositor-x11, and the Weston head-less back-end, among other changes.
The branching announcement was made to the mailing list while new Git commits can be found from browsing the repositories.
