Hi, I agree that our docs are not mentioning this anywhere. I would have expected it on this page: https://ci.apache.org/projects/flink/flink-docs-stable/ops/upgrading.html. I filed a ticket to address this: https://issues.apache.org/jira/browse/FLINK-19955
The only thing Flink officially guarantees is that a job compiled against 1.11.0 also compiles against 1.11.2. There could be protocol or format changes that could break if you are using a Flink job compiled against an older version. However, chances are high that the job will be effectively compatible with the 1.11.0 cluster, because we are not changing that much between minor releases.
