Apache Kafka 2.8 and 3.7 have reached end-of-life
Change effective on 28 October 2026
Heroku has deprecated support for all Apache Kafka on Heroku instances running on versions 2.8 and 3.7. This deprecation is part of our documented version support policy. Starting today we take action on any remaining clusters on Apache Kafka 2.8 and 3.7 for non-compliance according to our end-of-life policy.
