+
+#### Bug Fixes
+
+ * AMQP 0-9-1 channel exception generator could not handle entity names (say, queue or stream names)
+   that contained non-ASCII characters.
+
+   This affected applications that use passive queue declarations, such as the Shovel plugin.
+
+   Contributed by @bpint.
+
+   GitHub issue: [#12888](https://github.com/rabbitmq/rabbitmq-server/pull/12888)
+
+ * Reintroduced transient flow control between classic queue replicas and AMQP 0-9-1 channels,
+   MQTT connections.
+
+   Flow control between these specific parts of the core were unintentionally
+   removed in `4.0.0` together with classic queue mirroring.
+
+   Contributed by @gomoripeti.
+
+   GitHub issue: [#12907](https://github.com/rabbitmq/rabbitmq-server/pull/12907)
+
+ * AMQP 1.0 connections with a higher consumption rate could set the incoming window field
+   on the flow frame to a negative value, which resulted in an exception that affected the consumer.
+
+   GitHub issues: [#12816](https://github.com/rabbitmq/rabbitmq-server/issues/12816)
+
+ * In rare cases quorum queue could end up without an elected leader because
+   chosen candidate replica was not verified for aliveness.

+
+ * When a new replica is added to a quorum queue, the node that handles this request will now wait
+   the operation to complete. Previously an early return could result in confusing `cluster_change_not_permitted`
+   errors for subsequent operations, for example, an addition of another replica.
+
+   GitHub issue: [#12837](https://github.com/rabbitmq/rabbitmq-server/pull/12837)
+
+ * In very rare cases, RabbitMQ could fail to notify stream consumers connected to follower replicas
+   about newly committed offsets as quickly as it usually happens for consumers connected to the stream leader.

+### CLI Tools
+
+#### Enhancements
+
+ * New major version of `rabbitmqadmin`, a CLI tool that targets RabbitMQ's HTTP API, is maturing.
+   Unlike its predecessor, the tool is distirbuted via GitHub as as a standalone native binary.
+
+   There are minor command line interface changes and a slightly different configuration file
+   format ([TOML](https://toml.io/en/) instead of `ini`)

+   GitHub repository: [`rabbitmq/rabbitmqadmin-ng`](https://github.com/rabbitmq/rabbitmqadmin-ng)
