RabbitMQ - v3.10.13

RabbitMQ 3.10.13 is a maintenance release in the 3.10.x release series.

Please refer to the upgrade section from v3.10.0 release notes
if upgrading from a version prior to 3.10.0.

This release requires Erlang 24.2 and supports Erlang 25.
RabbitMQ and Erlang/OTP Compatibility Matrix has more details on
Erlang version requirements for RabbitMQ.

Minimum Supported Erlang Version

Erlang 23 support has reached its end of support.

This release of RabbitMQ requires Erlang 24.2 or later versions. Nodes will fail to start on older Erlang releases.

Erlang 25 is recommended: it offers much improved performance on ARM64 architectures, profiling with flame graphs
across all architectures, and the most recent TLS 1.3 implementation.

Changes Worth Mentioning

Core Server

Enhancements

• Backported a number of free disk space monitor resiliency improvements.

GitHub issue: #5831

• If handle.exe is not available, free disk space monitor will now shell out to PowerShell
  to retrieve the number of open file handles used by the node.

GitHub issue: #6613

• raft.adaptive_failure_detector.poll_interval exposes aten's poll_interval setting to
  RabbitMQ users. Increasing it can reduce the probability of false positives in clusters where
  inter-node communication links are used at close to maximum capacity.
  The default is 5000 (5 seconds).

GitHub issue: #6632

• When both disk_free_limit.relative and disk_free_limit.absolute,
  or both vm_memory_high_watermark.relative and vm_memory_high_watermark.absolute are set,
  the absolute settings will now take precedence.
