Hi Stefan,
From my perspective there are still some issues to be closed before the release (see
https://github.com/scikit-image/scikit-image/milestone/6). This year we have been using GitHub features extensively and they should represent our current point of view regarding the codebase status. Among the tagged issues there are some long-lasting ones, and these could be transfered into 0.13 roadmap. As for the others, I'd prefer to solve them first.
Above said, I'd suggest to push the release date a bit further. At least, the freeze initiation.
Regards,
Egor Panfilov
P.S. I'm traveling on the next week, and will not be able to contribute significant efforts till Dec'26th. However, I'll try to track the mailing list, and participate in the discussions (if any).
