RabbitMQ 3.12.4 is a maintenance release in the 3.12.x release series.
Please refer to the upgrade section from the 3.12.0 release notes
if upgrading from a version prior to 3.12.0.
This release requires Erlang 25 and supports Erlang versions up to 26.0.x.
RabbitMQ and Erlang/OTP Compatibility Matrix has more details on
Erlang version requirements for RabbitMQ.
Minimum Supported Erlang Version
As of 3.12.0, RabbitMQ requires Erlang 25. Nodes will fail to start on older Erlang releases.
Users upgrading from 3.11.x (or older releases) on Erlang 25 to 3.12.x on Erlang 26
(both RabbitMQ and Erlang are upgraded at the same time) must consult

Core Server
Bug Fixes
-
Consumer churn on quorum queues could result in some messages not being delivered
to consumers in certain cases. This mostly affected queue federation links.GitHub issue: #9158
Management Plugin
Bug Fixes
-
Quorum queue replica management operations over the HTTP API now can be
disabled. This can be useful in environments where replica management
is done by the platform team and tooling, and should not be exposed to
cluster users.Contributed by @SimonUnge (AWS).
GitHub issue: #9151
Federation Plugin
Bug Fixes

Queue federation links that connected quorum queues could get stuck
(stop transferring messages even when there were no other consumers on the upstream).GitHub issue: #9158
LDAP AuthN/AuthZ Backend Plugin
Bug Fixes

LDAP plugin did not interpolate values with non-ASCII characters correctly.
