+RabbitMQ `3.10.15` is a maintenance release in the `3.10.x` [release series](https://www.rabbitmq.com/versions.html).
+
+This series [**reaches end of general support** on July 31st, 2023](https://rabbitmq.com/versions.html).
+
+Please refer to the upgrade section from [v3.10.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.10.0)
+if upgrading from a version prior to 3.10.0.
+
+This release **requires Erlang 24.3** and supports Erlang 25.
+[RabbitMQ and Erlang/OTP Compatibility Matrix](https://www.rabbitmq.com/which-erlang.html) has more details on
+Erlang version requirements for RabbitMQ.
+
+
+### Minimum Supported Erlang Version
+
+Erlang 23 and 24 versions older than 24.3 have reached [end of support](https://www.rabbitmq.com/which-erlang.html).
+
+This release of RabbitMQ requires Erlang 24.3 or later versions. Nodes **will fail to start** on older Erlang releases.
+
+Erlang 25 is recommended: it offers much improved performance on ARM64 architectures, [profiling with flame graphs](https://blog.rabbitmq.com/posts/2022/05/flame-graphs/)
+across all architectures, and the most recent TLS 1.3 implementation.
+
+
+## Changes Worth Mentioning
+
+Release notes can be found on GitHub at [rabbitmq-server/release-notes](https://github.com/rabbitmq/rabbitmq-server/tree/v3.10.x/release-notes).
+
+
+### CLI Tools
+
+#### Features
+
+ * `rabbitmqctl hash_password` is a new command that produces a [hashed value](https://www.rabbitmq.com/passwords.html#computing-password-hash) of the provided password.
+
+   Contributed by @SimonUnge (AWS).
+
+   GitHub issue: [#5957](https://github.com/rabbitmq/rabbitmq-server/issues/5957)
+
+ * `rabbitmq-diagnostics check_port_connectivity` now supports a new optional flag, `--address`,
+   that makes the check connect to a specific IP address instead of resolving node's hostname.
+   This is useful when target node is configured to only listen for connections on one interface
+   but not others:
+
+   ``` shell
+   rabbitmq-diagnostics check_port_connectivity --address 127.0.0.1
+   rabbitmq-diagnostics check_port_connectivity --address "::1"
+   ```
+
+   GitHub issue: [#6853](https://github.com/rabbitmq/rabbitmq-server/issues/6853)
+
+
+### Management Plugin
+
+#### Bug Fixes
+
+ * User filtering combined with pagination in the management UI did not work as expected.
+
+   GitHub issue: [#4908](https://github.com/rabbitmq/rabbitmq-server/issues/4908)
+
+ * Correctly format JSON field value in channel detail API response.
+
+   Contributed @Syuparn.
+
+   GitHub issue: [#2684](https://github.com/rabbitmq/rabbitmq-server/issues/2684)
+
+
+### AMQP 1.0 Plugin
+
+#### Bug Fixes
+
+ * AMQP 1.0 connection churn resulted in a memory leak.
+
+   GitHub issue: [#6969](https://github.com/rabbitmq/rabbitmq-server/issues/6969)
