  * added orphaned events support to `EventDataCollector`
  * `ExceptionListener` now logs exceptions at priority `0` (previously logged at `-128`)
- * Deprecated `service:action` syntax with a single colon to reference controllers. Use `service::method` instead.
+ * Added support for using `service::method` to reference controllers, making it consistent with other cases. It is recommended over the `service:action` syntax with a single colon, which will be deprecated in the future.
  * Added the ability to profile individual argument value resolvers via the
