 ## Backward Incompatibilities {#sec-release-24.11-incompatibilities}
 
 - `transmission` package has been aliased with a `trace` warning to `transmission_3`. Since [Transmission 4 has been released last year](https://github.com/transmission/transmission/releases/tag/4.0.0), and Transmission 3 will eventually go away, it was decided perform this warning alias to make people aware of the new version. The `services.transmission.package` defaults to `transmission_3` as well because the upgrade can cause data loss in certain specific usage patterns (examples: [#5153](https://github.com/transmission/transmission/issues/5153), [#6796](https://github.com/transmission/transmission/issues/6796)). Please make sure to back up to your data directory per your usage:
