Hi Mickael, I did the following on RC2: - verified the checksums and signature - downloaded and build from source (java 21) + run quickstart - played with basic produce/consume, classic and consumer groups, mixed groups, online upgrade/downgrade - downloaded docker images & run quick start with both - browsed the docs +1 (binding) Thanks for running the release!

I am implementing a feature in Debo Data Studio that uses *PostgreSQL SQL scripts and LISTEN/NOTIFY functionality* to mimic core Kafka-like behaviors for smaller environments: - ...

Hi Apoorva, This is an open source project, so you can search in the JIRA or check the source code to find the answer. Like the first CVE-2025-67030, you will find this ticket after searching it: https://issues.apache.org/jira/browse/KAFKA-20373 And it showed it'll be included in v4.2.1/v4.3.0. If you find it is not fixed yet, submitting PRs to fix them is highly appreciated.
