question on jar compatibility - log4j related

If have jar files built using flink version 11.2 in dependencies, and I upgrade my cluster to 11.6, is it safe to run the existing jars on the upgraded cluster or should I rebuild all jobs against 11.6?

Thanks,
Eddie Colletta

Hi Eddie,

the APIs should be binary compatible across patch releases, so there is no
need to re-compile your artifacts

Best,
D.
