 - Fix a bug were the same IP could be assigned to multiple hosts if joined in quick succession [#346](https://github.com/juanfont/headscale/pull/346)
+- Simplify the code behind registration of machines [#366](https://github.com/juanfont/headscale/pull/366)
+  - Nodes are now only written to database if they are registrated successfully
+- Fix a limitation in the ACLs that prevented users to write rules with `*` as source [#374](https://github.com/juanfont/headscale/issues/374)
+- Reduce the overhead of marshal/unmarshal for Hostinfo, routes and endpoints by using specific types in Machine [#371](https://github.com/juanfont/headscale/pull/371)

+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
