Apache Kafka 3.7.1 is available in beta on Heroku

Change effective on 14 August 2024

Apache Kafka version 3.7.1 is now available in beta for Apache Kafka on Heroku. The beta provides an easy way for customers to try out the new release. Apache Kafka 2.8.2 continues to be the default version for new clusters until we make version 3.7.1 generally available.

You can provision a Kafka cluster with this version with the --version 3.7.1 flag.

$ heroku addons:create heroku-kafka:standard-0 -a example-app -- --version 3.7.1

You can also use kafka:upgrade to upgrade your database to version 3.7.1.

$ heroku kafka:upgrade --version 3.7.1

See the Kafka documentation for notable changes when upgrading to 3.7.1. For example, if you’re using Kafka Streams, the Streams API removed all APIs that were deprecated in version 2.5.0 and earlier. Also, Client APIs released before Apache Kafka 2.1 are deprecated in 3.7, and will be removed in Apache Kafka 4.0.
