RabbitMQ `3.11.23` 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.

### Core Server
|
||
|
|
|
||
|
|
#### Bug Fixes
|
||
|
|
|
||
|
|
* High consumer churn with reused consumer tag on quorum queues could result in some messages not being delivered
|
||
|
|
after a period of time.
|
||
|
|
|
||
|
|
This did not affect environments where consumer churn does not exist or where it does but consumer tags vary.
