RabbitMQ `3.11.22` 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).
### Management Plugin
#### Bug Fixes
* Quorum queue replica management operations over the HTTP API now can be
disabled. This can be useful in environments where replica management
is done by the platform team and tooling, and should not be exposed to
cluster users.
Contributed by @SimonUnge (AWS).
GitHub issue: [#9151](https://github.com/rabbitmq/rabbitmq-server/pull/9151)
### LDAP AuthN/AuthZ Backend Plugin
#### Bug Fixes
* LDAP plugin did not interpolate values with non-ASCII characters correctly.
