Hi Satish, I verified with: 1. Ran quick start in KRaft for scala 2.12 artifact 2. Making sure the checksum are correct 3. Browsing release notes, documents, javadocs, protocols.
I filed KAFKA-15491 <https://issues.apache.org/jira/browse/KAFKA-15491>for log output improvement while testing stream application. It won't be blocker in v3.6.0. For KAFKA-15489 <https://issues.apache.org/jira/browse/KAFKA-15489>, I'm fine if we decide to fix it in v3.6.1/v3.7.0. +1 (binding) from me. Thank you.
