RabbitMQ - v3.10.20

RabbitMQ 3.10.20 is a maintenance release in the 3.10.x release series.

This series reaches end of community support on July 31st, 2023.

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 24.3 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 and 24 versions older than 24.3 have reached end of support.

This release of RabbitMQ requires Erlang 24.3.4.8
or later versions. Nodes will fail to start on older Erlang releases.

Erlang 25.2 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.
