Hi Josep, Thanks for the RC.
I gave it a quick try and ran into issues with an application using the Kafka Admin API that looks like this issue: https://issues.apache.org/jira/browse/KAFKA-16905 ... given that this breaks what was working fine with Kafka 3.7, can the fix be backported to 3.8.0 as well? If needed, I tried to create a simple reproducer for the issue: https://github.com/scholzj/kafka-admin-api-async-issue-reproducer.
