Updating Apache Kafka on Heroku version support policy

Change effective on 28 July 2026

We are updating our Apache Kafka on Heroku version support policy to maintain a high level of service for our Kafka fleet. We require customers to upgrade their Kafka version roughly once per year as we deprecate older versions and introduce new versions. Kafka clusters on a deprecated version are subject to forced upgrade attempts, access revocations, and cluster deletion for non-compliance.

See version deprecation announcements on the Changelog.

Apache Kafka 2.8 and 3.7 deprecation on Heroku JRuby version 10.1.1.0 is now available
