Hi Everyone, According to https://kafka.apache.org/blog/releases/ , 4.2.0 was released on Feb 17, I'm wondering will kafka 4.1.2( https://cwiki.apache.org/confluence/display/KAFKA/Release+Plan+4.1.2 ) still be released and when? The page https://cwiki.apache.org/confluence/display/KAFKA/Future+release+plan does not mention 4.1.2. Can anyone help to clarify? Thanks Benson
