0.14.0 (2022-02-24)

**UPCOMING ### BREAKING From the **next** version (0.15.0), all machines will be able to communicate regardless of if they are in the same namespace. This means that the behaviour currently limited to ACLs will become default. From version 0.15.0, all limitation of communications must be done with ACLs.

This is a part of aligning headscale's behaviour with Tailscale's upstream behaviour.

BREAKING

• ACLs have been rewritten to align with the bevaviour Tailscale Control Panel provides. NOTE: This is only active if you use ACLs
  • Namespaces are now treated as Users
  • All machines can communicate with all machines by default

  • The documentation have a fictional example that should cover some use cases of the ACLs features
