Is the agenda of the technical board meetings published in advance somewhere? For the previous meeting, it was published: https://bimestriel.framapad.org/p/r.a5199d22813a5ac79d1d365b9cecb905 For the next one, please Konstantin, could you publish the agenda on a pad? > > > How do we manage the API freeze on the next-tree?

We definitely welcome change requests done in a timely manner. My concern is about last minute change requests, such as major API change requests just a few days before the release when driver development is complete. Is there a policy in place to prevent against such events for next-tree type of development? No there is no such policy on a next- tree. It is free to the maintainer of the tree I guess.
