 - `services.taskchampion-sync-server` module have been added an option `services.taskchampion-sync-server.dynamicUser` to use systemd's DynamicUser feature. This is enabled by default when stateVersion is at least 26.05, and disabled otherwise. If you need this feature, you need to set `services.taskchampion-sync-server.dynamicUser` to `true` and migrate `/var/lib/taskchampion-sync-server` to `/var/lib/private/taskchampion-sync-server`.
 
+- Package `jellyseerr` has been renamed to `seerr` following the upstream rename.
+
 - The default packages in `services.jenkins.packages` have been dropped, since not every Jenkins installation needs any package at all. It's more reasonable to leave it empty and let users configure what they need.

 - `geph` package's built-in GUI `geph5-client-gui` has been [removed](https://github.com/geph-official/geph5/commit/f2221fb8386312daf2cef05483ebb353ff48bdb4) by the upstream. All users who wish to continue using the GUI should install the `gephgui-wry`, which is consistent with the official release version.
 
+- `services.jellyseerr` has been renamed to `services.seerr` following the upstream changes. Notable breaking changes:
+  - systemd service name changed accordingly.
+  - Default config directory moved from `/var/lib/jellyseerr/config` to `/var/lib/seerr/`.
+    - If `stateVersion` is older than `26.05`, the module fall backs to the legacy path value.

 - `services.vikunja` has been updated to Vikunja [v1.0.0](https://vikunja.io/changelog/whats-new-in-vikunja-1.0.0/), which introduces multiple breaking changes.
