+## RabbitMQ 3.13.5
+
+RabbitMQ `3.13.5` is a maintenance release in the `3.13.x` [release series](https://www.rabbitmq.com/release-information).
+This upgrade is **highly recommended** to all users currently on earlier `3.13.x` series and
+in particular `3.13.4`.
+
+Starting June 1st, 2024, community support for this series will only be provided to [regularly contributing users](https://github.com/rabbitmq/rabbitmq-server/blob/main/COMMUNITY_SUPPORT.md) and those
+who hold a valid [commercial support license](https://tanzu.vmware.com/rabbitmq/oss).
+
+Please refer to the upgrade section from the [3.13.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.13.0)
+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](https://www.rabbitmq.com/docs/which-erlang) 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](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.12.0) and [v3.13.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.13.0) first.
