- Add APIs for managing headscale policy. [#1792](https://github.com/juanfont/headscale/pull/1792)
- Fix for registering nodes using preauthkeys when running on a postgres database in a non-UTC timezone. [#764](https://github.com/juanfont/headscale/issues/764)
- Make sure integration tests cover postgres for all scenarios
- CLI commands (all except `serve`) only requires minimal configuration, no more errors or warnings from unset settings [#2109](https://github.com/juanfont/headscale/pull/2109)
- CLI results are now concistently sent to stdout and errors to stderr [#2109](https://github.com/juanfont/headscale/pull/2109)
