Hi Roc, just as an addition to Congxian, Flink 1.11 will be released soonish. We just started the release process (created release branch to freeze the features), which should include 2-4 weeks of testing/bug fixing. Of course, if you are interested, you could use the current master/release branch and try it for yourself. We could also inform you of the first release candidate RC0, which I suspect at the end of this week/beginning of next week.
