RabbitMQ 3.11.21
is a maintenance release in the 3.11.x
release series.
This release series goes out of community support on Dec 31, 2023.
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
-
Certain diagnostics operations during rolling upgrades from 3.10 to 3.11 could fail
if thelistener_records_in_ets
feature flag was enabled in the middle of the upgrade.Contributed by @gomoripeti (CloudAMQP).
GitHub issue: #8984
-
On Windows, PowerShell will no longer be used as a fallback for
handle.exe
for computing how many file and socket handles a node uses.If a user does not have
handle.exe`` installed in the
PATH`` of their Windows system,
a message will be logged once, and then the total handles being used will be set to 0.PowerShell ended up being a CPU-intensive alternative that's not worth the gains
for many installations.GitHub issue: #8700
-
Node maintenance state was not replicated to all nodes, even though it was accessible
from any node (and for any node).GitHub issue: #9011
