RabbitMQ 3.12.12

Core Broker

Bug Fixes

Environments with a lot of quorum queues could experience a large Erlang process
build-up. The build-up was temporary but with a sufficiently large number of
quorum queues it could last until the next round of periodic operations,
making it permanent and depriving the node of CPU resources.

RabbitMQ core failed to propagate more authentication and authorization context, \ 
for example,
MQTT client ID in case of MQTT connections, to authN and authZ backends. This \ 
was not intentional.

Nodes now takes more precaution about persisting feature flag state
(specifically the effects of in-flight changes) during node shutdown.

Enhancements

Simplified some type specs.

Stream Plugin

One returned error value did not match the RabbitMQ Stream Protocol specification.

MQTT Plugin

Bug Fixes

Recovering connections from QoS 0 consumers (subscribers) could fail if they \ 
were previously connected to a failed node.
