Hi, Guozhang, Thanks for running the release. Just a quick clarification. The statement that "* Controller improvements: async ZK access for faster administrative request handling" is not accurate. What's included in 1.0.0 is a logging change improvement in the controller, which does give significant perf benefit. However, the async ZK changes are in trunk and will be in 1.1.0.
