RabbitMQ 3.13.6

RabbitMQ 3.13.6 is a maintenance release in the 3.13.x release series.

This upgrade is highly recommended to all users currently on earlier 3.13.x series and in particular between 3.13.3 and 3.13.5, inclusive.

Starting June 1st, 2024, community support for this series will only be provided to regularly contributing users and those who hold a valid commercial support license.

Please refer to the upgrade section from the 3.13.0 release notes if upgrading from a version prior to 3.13.0.

This release requires Erlang 26 and supports Erlang versions up to 26.2.x. RabbitMQ and Erlang/OTP Compatibility Matrix has more details on Erlang version requirements for RabbitMQ.

Minimum Supported Erlang Version

As of 3.13.0, RabbitMQ requires Erlang 26. Nodes will fail to start on older Erlang releases.

Users upgrading from 3.12.x (or older releases) on Erlang 25 to 3.13.x on Erlang 26 (both RabbitMQ and Erlang are upgraded at the same time) must consult the v3.12.0 release notes and v3.13.0 release notes first.
