We’ve created the 2021.10 release branch, so we are now officially in
feature freeze. This means from now only bugfixes will be backported to
2021.10-branch. If anyone has any bugfixes or documentation
improvements that they feel should be part of this release please let me know.
New features can still be merged into master during this period.
The test tracking issue of release candidate  is opened. Help with testing and resources for the testing is as always very welcome. Most of the testing is automated , but some stuff still needs to be run manually. So if you want to help, please put your name after the corresponding item in the linked issue to streamline the testing efforts.
Thanks all for the awesome work!
