+- Add experimental support for [SSH ACL](https://tailscale.com/kb/1018/acls/#tailscale-ssh) (see docs for limitations) [#847](https://github.com/juanfont/headscale/pull/847)
+ - Please note that this support should be considered _partially_ implemented
+ - SSH ACLs status:
+ - Support `accept` and `check` (SSH can be enabled and used for connecting and authentication)
+ - Rejecting connections **are not supported**, meaning that if you enable SSH, then assume that _all_ `ssh` connections **will be allowed**.
+ - If you decied to try this feature, please carefully managed permissions by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your clients.
+ - We are currently improving our testing of the SSH ACLs, help us get an overview by testing and giving feedback.
+ - This feature should be considered dangerous and it is disabled by default. Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.
