+RabbitMQ `3.11.16` 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 and supports Erlang versions up to `25.3.x`.
+[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
+
+Release notes can be found on GitHub at [rabbitmq-server/release-notes](https://github.com/rabbitmq/rabbitmq-server/tree/v3.11.x/release-notes).
+
+### Core Server
+
+#### Bug Fixes
+
+ * [Automatic node removal](https://rabbitmq.com/cluster-formation.html#node-health-checks-and-cleanup) now will
+   [remove quorum queue replicas](https://rabbitmq.com/quorum-queues.html#replica-management) from the node before removing it from the cluster.
+
+   Contributed by @SimonUnge (AWS).
+
+   GitHub issue: [#2882](https://github.com/rabbitmq/rabbitmq-server/issues/2882)
+
+#### Enhancements
+
+ * A new boolean setting, `quorum_queue.property_equivalence.relaxed_checks_on_redeclaration`,
+   makes it possible to relax queue property equivalence checks
+   for quorum queues. Specifically, when a quorum queue is redeclared and the client-provided
+   type is set to "classic", this setting will help avoid a channel exception, making it
+   easier to migrate to quorum queues step by step, without upgrading all applications in a short
+   period of time.
+
+   Contributed by @SimonUnge (AWS).
+
+   GitHub issue: [#8076](https://github.com/rabbitmq/rabbitmq-server/issues/8076)
+
+
+### CLI Tools
+
+#### Enhancements
+
+ * `rabbitmq-queues grow` and `rabbitmq-queues add_member` now verify cluster membership of the node
+   new quorum queue replicas should be placed on.
+
+   GitHub issue: [#8007](https://github.com/rabbitmq/rabbitmq-server/issues/8007)
+
+
+### Federation Plugin
+
+#### Bug Fixes
+
+ * URI parser incorrectly used the `password` query parameter to override the password
+   value in authority (user info) part.
+
+   The `password` query parameter can be used to specify private key password for
+   upstream connections that use TLS.
+
+   GitHub issue: [#8129](https://github.com/rabbitmq/rabbitmq-server/issues/8129)
+
+
+### Shovel Plugin
+
+#### Bug Fixes
+
+ * URI parser incorrectly used the `password` query parameter to override the password
+   value in authority (user info) part.
+
+   The `password` query parameter can be used to specify private key password for Shovels
+   that use TLS.
