Hello! I went through all commits which made it into this release and adjusted the ones which were not marked with 4.3.1. The ones I found were KAFKA-20335, KAFKA-20336 and KAFKA-20569, let me know if you disagree with the tag.
I further ran the quickstart against both Docker images, compiled the source and ran unit and integration tests, ran the quickstart against the compiled binaries, verified keys and the signatures of files. +1 (binding) Thanks for leading the release!
