Stability, Compatibility and Testing
3.3.6 is a stable release that’s fully backward compatible with 3.3.5. Only bug fixes relative to 3.3.5 have been applied.
The Apache ZooKeeper project is working on a number of new features. Our How To Contribute page is a great place to start if you’re interested in getting involved as a developer. You can also follow me on twitter.
A special thanks to everyone who contributed to the release (reporting issues, fixing bugs, reviewing changes, writing documentation, etc).
