|  | RabbitMQ `3.11.15` 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
 | ||
|  | 
 | ||
|  |  * Operator policies now can define `"ha-sync-mode"`, a classic mirrored queue setting. Note that classic mirrored queues are | ||
|  |    [deprecated and will be removed in RabbitMQ 4.0](https://blog.rabbitmq.com/posts/2021/08/4.0-deprecation-announcements/). | ||
|  | 
 | ||
|  |    All users of CMQs should [migrate to quorum queues](https://blog.rabbitmq.com/posts/2023/02/quorum-queues-migration/) or [streams](https://rabbitmq.com/streams.html), | ||
|  |    or a combination of both. | ||

 | ||
|  | ### RPM Package
 | ||
|  | 
 | ||
|  | #### Bug Fixes
 | ||
|  | 
 | ||
|  |  * The package unintentionally limited supported Erlang versions to `<= 25.3.0` instead of `< 26`. | ||
