+RabbitMQ `3.11.24` is a maintenance release in the `3.11.x` [release series](https://www.rabbitmq.com/versions.html).
+This release series [goes out of community support on Dec 31, 2023](https://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
+
+ * Stream replication connections configured to use exclusively TLSv1.3 failed.
+
+   GitHub issue:[#9678](https://github.com/rabbitmq/rabbitmq-server/pull/9678)
+
+ * On startup, stream replicas will handle one more potential case of segment file corruption
+   after an unclean shutdown.
+
+   Contributed by @gomoripeti (CloudAMQP).
+
+   GitHub issue: [#9678](https://github.com/rabbitmq/rabbitmq-server/pull/9678)
+
+ * `default_policies.*.queue_pattern` definition in `rabbitmq.conf` was incorrectly parsed.
+
+   Contributed by @SimonUnge (AWS).
+
+   GitHub issue: [#9546](https://github.com/rabbitmq/rabbitmq-server/pull/9546)
+
+#### Enhancements
+
+ * Optimized stream index scans. Longer scans could result in some replicas stopping
+   with a timeout.
+
+   GitHub issue:[#9678](https://github.com/rabbitmq/rabbitmq-server/pull/9678)
+
+ * Classic queue storage version is now a supported key for [operator policies](https://rabbitmq.com/parameters.html#operator-policies).
+
+   Contributed by @SignalWhisperer (AWS).
+
+   GitHub issue: [#9549](https://github.com/rabbitmq/rabbitmq-server/pull/9549)
+
+ * Nodes now log boot time at info level instead of debug. This piece of information
+   can be useful during root cause analysis.
+
+   Contributed by @johanrhodin (CloudAMQP).
+
+   GitHub issue: [#9466](https://github.com/rabbitmq/rabbitmq-server/pull/9466)
+
+
+### Management Plugin
+
+#### Enhancements
+
+ * HTTP API request body size is now limited to 10 MiB by default.
+   Two endpoints, one that accepts messages for publishing (note: publishing over the HTTP API is greatly discouraged)
+   and another for [definition import](https://rabbitmq.com/definitions.html#import),
+   will now reject larger transfers with a `400 Bad Request` response.
+
+   GitHub issue: [#9708](https://github.com/rabbitmq/rabbitmq-server/pull/9708)
+
+ * `DELETE /api/queues/{vhost}/{name}` now can delete exclusive queues.
+
+   GitHub issue: [#8758](https://github.com/rabbitmq/rabbitmq-server/issues/8758)
+
+
+## Dependency Upgrades

+ * `osiris` has been upgraded to [`1.6.9`](https://github.com/rabbitmq/osiris/releases)
