Release notes can be found on GitHub at [rabbitmq-server/release-notes](https://github.com/rabbitmq/rabbitmq-server/tree/v3.10.x/release-notes).

### Core Server

 * Configuration of fallback secrets for Shovel and Federation credential obfuscation.
   This feature allows for secret rotation during rolling cluster node restarts.

   Contributed by Lajos @luos Gerecs.

   GitHub issue: [#4852](https://github.com/rabbitmq/rabbitmq-server/pull/4852)

### CLI Tools

#### Enhancements

 * `rabbitmq-diagnostics status` now reports crypto library (OpenSSL, LibreSSL, etc)
   used by the runtime, as well as its version details.

   GitHub issue: [#4799](https://github.com/rabbitmq/rabbitmq-server/issues/4799)

#### Bug Fixes
 * CLI tools failed to run on Erlang 25 because of an old version of Elixir (compiled on Erlang 21)
   was used in the release pipeline. Erlang 25 no longer loads modules
   compiled on Erlang 21 or older.

 * `rabbitmqctl set_log_level` documentation clarification.

   Contributed by Péter @gomoripeti Gömöri (CloudAMQP).

   GitHub issue: [#4794](https://github.com/rabbitmq/rabbitmq-server/pull/4794)
