Out of the 5 failures 3 were flaky (rerun was successful) and 2 are persistent. I checked them back against 4.0.1 and 3.9.1 and they seem to be present throughout the releases, so not new failures:
- tests/kafkatest/tests/core/network_degrade_test.py::NetworkDegradeTest.test_rate@{"task_name":"rate-1000-latency-50","device_name":"eth0","latency_ms":50,"rate_limit_kbit":1000000,"metadata_quorum":"COMBINED_KRAFT"}
- tests/kafkatest/tests/tools/replica_verification_test.py::ReplicaVerificationToolTest.test_replica_lags@{"metadata_quorum":"ISOLATED_KRAFT"}

* Successful Docker Image Github Actions Pipeline for 4.0 branch:
Docker Build Test Pipeline (JVM): https://github.com/apache/kafka/actions/runs/22062306029
Docker Build Test Pipeline (Native): https://github.com/apache/kafka/actions/runs/22062316512

Thanks,
Viktor

Hello!

I did the following to validate the release candidate:

* Did a few random walks through the RELEASE NOTES, Javadocs, Maven
artifacts, and repository
* Checked the signatures of the tgzs with their keys
* Compiled the src.tgz and ran the quickstart against the compiled source
* Ran the quickstart against the binaries.tgz
* Ran the quickstarts against both Docker images
* Ran the system tests with no failures different to the ones you note

My only note is to include a short blog post as a follow-up :)

+1 (non-binding)

Best,
Christo

Thanks Christo,

In the meantime I created a PR for the missing doc changes: https://github.com/apache/kafka-site/pull/807 

Will create a blog post early next week too.

Best,
Viktor
