# Akka 2.0.1 Released!

Five weeks after the release of the very well received version 2.0, we have accumulated enough small fixes and enhancements to warrant a binary compatible bugfix release.

We would like to thank our great community for not only reporting, but also helping in fixing the issues which turned up: starting from very precise diagnostic information, over fixing errors in the documentation to submitting complete pull requests for performance enhancement. Special thanks go to Jean-François Im , Mathias Doenitz and Vibul Imtarnasan !

The issues fixed are:

- improved Java API for accessing singletons like akka.routing.CurrentRoutees and friends (also our beloved PoisonPill)
- reject invalid ActorSystem names which lead to problems when going remote (essentially must be valid hostname components now)
- fixed a live-lock in ForkJoinPool which could occur under rare circumstances with parallelism levels 2 or 4
- reduced overhead of ask() : less memory footprint and lazy registration
