Hi David, The policy is that the current and and previous minor release are supported, and it's documented at https://flink.apache.org/downloads/#update-policy-for-old-releases One of the reasons for decoupling the connectors from Flink is that it could be possible to support older versions of Flink as well. That depends of course on the complexity of the backport etc which is a case-by-case situation.
