+## RabbitMQ 4.0.5
+
+RabbitMQ `4.0.5` is a maintenance release in the `4.0.x` [release series](https://www.rabbitmq.com/release-information).

+who hold a valid [commercial support license](https://tanzu.vmware.com/rabbitmq/oss).
+
+It is **strongly recommended** that you read [4.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.0.1)
+in detail if upgrading from a version prior to `4.0.0`.

+This release requires Erlang 26 and supports Erlang versions up to `27.2.x`.
+[RabbitMQ and Erlang/OTP Compatibility Matrix](https://www.rabbitmq.com/docs/which-erlang) has more details on
+Erlang version requirements for RabbitMQ.
+
+Nodes **will fail to start** on older Erlang releases.
+
+
+## Changes Worth Mentioning
+
+Release notes can be found on GitHub at [rabbitmq-server/release-notes](https://github.com/rabbitmq/rabbitmq-server/tree/v4.0.x/release-notes).
+
+### Core Broker
+
+#### Bug Fixes
+
+ * 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)
+
+ * The feature that warns when deprecated features are used in the cluster had a false positive that treated (and reported) any queue
+   as a "transient non-exclusive classic queue", even if the queue was of a different type, was not transient, and so on.
+
+   GitHub issue: [#12802](https://github.com/rabbitmq/rabbitmq-server/issues/12802)
+
+ * AMQP 1.0 clients with close to peak consumption rates with a high `max_link_creadit` setting could run into an exception
+   because RabbitMQ could set the incoming window size to a negative value.
+
+   GitHub issue: [#12816](https://github.com/rabbitmq/rabbitmq-server/issues/12816), [#12904](https://github.com/rabbitmq/rabbitmq-server/pull/12904)
+
+ * 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)
+
+ * Peer discovery resilience improvements.
+
+   GitHub issues: [#12801](https://github.com/rabbitmq/rabbitmq-server/pull/12801), [#12809](https://github.com/rabbitmq/rabbitmq-server/pull/12809)
+
+ * Deadlettering of some messages could result in an exception.
+
+   GitHub issue: [#12933](https://github.com/rabbitmq/rabbitmq-server/issues/12933), [#12938](https://github.com/rabbitmq/rabbitmq-server/pull/12938)
+
+#### Enhancements
+
+ * For virtual hosts that have a [default queue type]() configured, the DQT value is now injected into
+   queue definitions in exported definition documents.
+
+   GitHub issue: [#12776](https://github.com/rabbitmq/rabbitmq-server/issues/12776)
+
+ * Definition export files now have additional "type" markers that help distinguish a cluster-wide definition file from
+   that of a single virtual host.
+
+   GitHub issue: [#12835](https://github.com/rabbitmq/rabbitmq-server/issues/12835)
+
+
+### Prometheus Plugin and Grafana Dashboards
+
+#### Enhancements
+
+ * Two new stream metrics for streams.
+
+   Contributed by @gomoripeti and @markus812498.
+
+   GitHub issue: [#12765](https://github.com/rabbitmq/rabbitmq-server/pull/12765)
+
+
+### Management Plugin
+
+#### Bug Fixes
+
+ * Fixes a false positive that incorrectly reported deprecated feature use, specifically
+   the use of non-exclusive transient classic queues.
+
+   GitHub issue: [#12840](https://github.com/rabbitmq/rabbitmq-server/pull/12840)
+
+ * `GET /api/overview` did not format empty cluster and node list tags as an empty JSON object,
+   which was problematic for HTTP API clients with statically typed response data structures.
+
+   GitHub issue: [#12797](https://github.com/rabbitmq/rabbitmq-server/pull/12797)
+
+ * When a logged in user's JWT token was refreshed, the user identity displayed in the UI was changed.
+
+   GitHub issue: [#12818](https://github.com/rabbitmq/rabbitmq-server/pull/12818)
+
+
