I as the one who released the build can say the following:
As GvG, also I didn't know about the mentioned documents, nor about wheter they were agreed or something else. Off course, I might have informed myself, but it was not the first time I did a release. Since I see it the same way GvG does "release often" (and also with bugs) I did it that way. I have to admit, that I did't put any eye into bugzilla to look for blockers, but in my backmind this seemed not so necessary. So decided mechanical to not look out for blockers and just release. Of couse just after I had a little test in qemu.
So far. At least: The release works (but shutdown) and ist testable. As I think exactly what "release often" means...
