Hey folks, we found a couple of blockers with RC1 and have fixed them in
the latest release candidate, RC2.
The major features of this release include:
* KIP-881: Rack-aware Partition Assignment for Kafka Consumers
<https://cwiki.apache.org/confluence/display/KAFKA/KIP-881%3A+Rack-aware+Partition+Assignment+for+Kafka+Consumers>
* KIP-876: Time based cluster metadata snapshots
<https://cwiki.apache.org/confluence/display/KAFKA/KIP-876%3A+Time+based+cluster+metadata+snapshots>
* KIP-787: MM2 manage Kafka resources with custom Admin implementation.
<https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=191335620>

Test results:
We haven't had a 100% passing build, but the latest system test run looks
pretty good:

Here are the Jenkins test runs for 3.4:
https://ci-builds.apache.org/job/Kafka/job/kafka/job/3.4/. We will continue
trying to diagnose the flaky test failures as the release continues. I do
not expect that any of these test failures are blockers for the release.
Thanks!
