release-notes/3.12.9.md
RabbitMQ 3.12.9 is a maintenance release in the 3.12.x release series.
Please refer to the upgrade section from the 3.12.0 release notes if upgrading from a version prior to 3.12.0.
This release requires Erlang 25 and supports Erlang versions up to 26.1.x.
RabbitMQ and Erlang/OTP Compatibility Matrix has more details on
Erlang version requirements for RabbitMQ.
As of 3.12.0, RabbitMQ requires Erlang 25. Nodes will fail to start on older Erlang releases.
Users upgrading from 3.11.x (or older releases) on Erlang 25 to 3.12.x on Erlang 26 (both RabbitMQ and Erlang are upgraded at the same time) must consult the v3.12.0 release notes first.
Release notes can be found on GitHub at rabbitmq-server/release-notes.
When a topic permission was deleted, an internal event of type permission.deleted
was emitted in some cases, instead of topic.permission.deleted.
