Feature Freeze

[Paul Spooren]

Dear all,

as discussed during our last member meeting, there is now a feature freeze in place! Please don't commit any major changes until the planed branch around March 20th.

After the branch heavy changes (i.e. Kernel 5.15) can be merged, for now we should work on bugs and finish up `firewall4` support.

March 20th is **not** the release date of 22.0x, after the branch we'll give it more time to stabilize.

Best,
Paul
