- Actors are now registered in `pykka.registry.ActorRegistry` before they are started. This fixes a race condition where an actor tried to stop and unregister itself before it was registered, causing an exception in `ActorRegistry.unregister`.
0.12.1
- Stop all running actors on `BaseException` instead of just `KeyboardInterrupt`, so that `sys.exit(1)` will work.
0.12
- First stable release, as Pykka now is used by the [Mopidy](https://mopidy.com/) project. From now on, a changelog will be maintained and we will strive for backward compatibility.
