• Deployed Multi-Node Cluster in KRaft Mode (without Zookeeper)
• Can confirm that KAFKA-13456 works as expected after switching to 3.1.0

Hi David,

Thanks for running the release!

I did the following:

1. Validated all signatures and keys
2. Built from source
3. Ran all the unit tests
4. Spot checked the java docs, and the site docs
5. Ran a portion of the quick start 
6. Ran the Kafka Streams demo application 

I noticed one small error on the quick start page: the  "Kafka Streams demo and the app development tutorial" links still reference the 2.5 release.  

This is a very minor issue and it doesn't require a new RC, we can simply update the links once released.

+1(binding)

Thanks,

Bill

Thanks David for running this release!

I checked signatures and keys, built from source and ran unit tests
with Java 11. I also ran the quickstart.

+1 (binding)

Thanks for all the votes!

I'm also +1 (binding) given that:

* Ran the release and generated 3.1.0 RC1.
* Verified all checksums and signatures.
* Built from source and ran unit tests.
* Installed 3.1.0 RC1 and performed the quickstart for both ZK and KRaft.
* Spotchecked the Javadocs and the site doc.

I will close the vote shortly.

Best,
David
