Thanks for cutting the first RC.
I just want to point to the email on the dev list with subject: `Kafka
tags on repo`.
It seems, our release scripts have some issue. David Arthur is actively
investigation: https://issues.apache.org/jira/browse/KAFKA-19166
Apparently something is not pushed correctly, cf
https://github.com/apache/kafka/commit/3cb4749195b9bfcfa64f6b5855a019dfbd173ed4
which say
This commit does not belong to any branch on this repository, and may belong to
a fork outside of the repository.
While the RC can be verified, we should hold off to moving forward with
the release until the root cause of this issue was identified and fixed.
