- [wg-access-server](https://github.com/freifunkMUC/wg-access-server/), an all-in-one WireGuard VPN solution with a web ui for connecting devices. Available at [services.wg-access-server](#opt-services.wg-access-server.enable).

- [Playerctld](https://github.com/altdesktop/playerctl), a daemon to track media player activity. Available as [services.playerctld](option.html#opt-services.playerctld).

## 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)).
