As mentioned a few days back, Pekka at Collabora has been working on planning out the Wayland/Weston 1.6 release with Kristian working on other projects this summer.
Pekka Paalanen wrote in today's alpha announcement that Wayland will be transitioning more to a community project, "We have moved from a dedicated maintainer (Kristian) project to a community maintained project, where several key people have commit rights, but no-one is dedicated as the maintainer, at least yet. Things started very slowly and the review backlog grew enormous, as Kristian was no longer heroically reviewing and committing everything, and everyone had their own $jobs to do. Collabora agreed to let me run the alpha release as I had a convenient break from other projects, so you could say this release is brought to you by Collabora. ;-)"
The plan after today's alpha release is to do a release candidate on 5 September, a second RC on 12 September, and to do the final release on 19 September. More information on today's Wayland 1.6 alpha release can be found via the Wayland-devel list.
