Subject Re: KafkaStreams: ProducerFencedException causing StreamThread death
Date Mon, 01 Oct 2018 19:27:53 GMT
Hi Aravind,

The tagged versions may not be released yet, we just tag them when the
corresponding fix commit is merged to the branch (e.g. 1.1.x, 2.0.x, etc).
The next release that will include this commit is 2.1.0, whose feature
freeze date is today:
