3.11.8 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.
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.
