As of a few seconds ago we have new branches for Flow 3.1 and Neos 2.1 - so make sure to target your PRs to the correct branches.
Bugfixes should always be targeted at the lowest supported (and affected) branch, so for now this means probably every bugfix that was/is currently targeted at master should be re-opened for 2.1. Sadly there is no other way… But it’s easy, just checkout the new branch and cherry-pick the needed commits, push to your fork and create a new PR, then close the old (and leave a notice there about the new PR).
For the new branches, no new features must be merged. If in doubt, get in touch with someone from the Minions team.
Any other needed branches (distributions, other packages if needed, …) will be created tomorrow, along with the needed adjustments to build jobs and other tooling.
