RabbitMQ 3.11.16
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
-
Automatic node removal now will
remove quorum queue replicas from the node before removing it from the cluster.Contributed by @SimonUnge (AWS).
GitHub issue: #2882
Enhancements
-
A new boolean setting,
quorum_queue.property_equivalence.relaxed_checks_on_redeclaration
,
makes it possible to relax queue property equivalence checks
for quorum queues. Specifically, when a quorum queue is redeclared and the client-provided
type is set to "classic", this setting will help avoid a channel exception, making it
easier to migrate to quorum queues step by step, without upgrading all applications in a short
period of time.Contributed by @SimonUnge (AWS).
GitHub issue: #8076
