+RabbitMQ `3.11.12` is a maintenance release in the `3.11.x` [release series](https://www.rabbitmq.com/versions.html).
+
+Please refer to the upgrade section from [v3.11.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.11.0)
+if upgrading from a version prior to 3.11.0.
+
+This release requires Erlang 25.
+[RabbitMQ and Erlang/OTP Compatibility Matrix](https://www.rabbitmq.com/which-erlang.html) has more details on
+Erlang version requirements for RabbitMQ.
+
+
+### Minimum Supported Erlang Version
+
+As of 3.11.0, RabbitMQ requires Erlang 25. Nodes **will fail to start** on older Erlang releases.
+
+Erlang 25 as our new baseline means much improved performance on ARM64 architectures, [profiling with flame graphs](https://blog.rabbitmq.com/posts/2022/05/flame-graphs/)
+across all architectures, and the most recent TLS 1.3 implementation available to all RabbitMQ 3.11 users.
+
+
+## Changes Worth Mentioning
