With 9.2 CR2 built, master will be converted to 9.3. 9.3 will remain a focused release - there are currently only 35 issues assigned so that we can get it out early if need be. Ideally we'll have the first Alpha of 9.3 out about 2 weeks after the 9.2 final. The documentation will be branched later as there as still several issues to be resolved.
A 9.2.x has been created off of master. We'll likely have the first 9.2.x release about 2-3 weeks after the Final release.
The final 9.0.x release will at around the same time as 9.2.1.
