RabbitMQ `3.11.17` 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.

### Core Server
|
|
|
|
#### Bug Fixes
|
|
|
|
* Fixed two quorum queue federation issues.
|
|
|
|
GitHub issue: [#8282](https://github.com/rabbitmq/rabbitmq-server/pull/8282)

|

|
|
|
* Nodes could hang when recovering classic queue indices during boot.
|
|
|
|
GitHub issue: [#8343](https://github.com/rabbitmq/rabbitmq-server/pull/8343)
|
|
|
|
* As of [#6418](https://github.com/rabbitmq/rabbitmq-server/pull/6418), nodes refuse
|
|
to start if the definitions file cannot be parsed as valid JSON.
|
|
|
|
Now this also applies to nodes that were configure to skip definition import if the input file(s) has changed
|
|
using the `definitions.skip_if_unchanged` setting.
