RabbitMQ 3.11.17

on GitHub

RabbitMQ 3.11.17 is a maintenance release in the 3.11.x release series.

Please refer to the upgrade section from v3.11.0 release notes
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 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
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

• Nodes that had a large number of quorum queues could observe accumulation of Erlang processes
  under significant load.

  Contributed by @SimonUnge (AWS).

  GitHub issue: #7389

• Nodes could hang when recovering classic queue indices during boot.

  GitHub issue: #8343

• As of #6418, nodes refuse

  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.
