@maiste I think next week you can go ahead with the 3.20.2 release. I probably won't be able to finish #12360 in the way that I want for that, but there is no point holding the other patches back. I will defer it to a future 3.20.3.

We just need a changelog for #12324. There was a similar change in 3.20.1 that you can use for inspiration.

Ok, thanks for the follow-up! I'll do it today or tomorrow. For #12360, fo you think it can be delayed to 3.21? I'm planning the release for the end of september.
