Hi, I am going to prepare a release candidate for ZooKeeper 3.6.1. There is no JIRA issue with fixVersion = 3.6.1 that is unresolved.
I have tested a few projects that had compatibility issues and they are resolved (like Apache BookKeeper and other non OS projects in my company). I remember that Norbert pointed a problem with HBase client, that uses getRevision() method, it would be super great to have some feedback of compatibility of HBase with 3.6.1 client. I have deployed the snapshots to snapshots.apache.org, this way you can easily test your project in CI, even on Travis. I have created the work branch for release https://github.com/apache/zookeeper/tree/release-3.6.1 Please ping me if you have any questions or concerns or you need to add new items. I will start the release procedure once I have self validated the status of that branch Stay tuned Enrico
