Subject [VOTE] 2.5.0 RC1
Date Tue, 10 Mar 2020 03:21:15 GMT
Hello Kafka users, developers and client-developers,

This is the second candidate for release of Apache Kafka 2.5.0. The first
release candidate included an erroneous NOTICE file, so another RC was
needed to fix that.

This is a major release of Kafka which includes many new features,
improvements, and bug fixes including:

* TLS 1.3 support (1.2 is now the default)
* Co-groups for Kafka Streams
* Incremental rebalance for Kafka Consumer
* New metrics for better operational insight
* Upgrade Zookeeper to 3.5.7
* Deprecate support for Scala 2.11

Release notes for the 2.5.0 release:
