   release notes of [v19](https://github.com/systemd/mkosi/releases/tag/v19) and
   [v20](https://github.com/systemd/mkosi/releases/tag/v20) for a list of changes.
 
+- The `services.vikunja` systemd service now uses `vikunja` as dynamic user instead of `vikunja-api`. Database users might need to be changed.
+
 - The `woodpecker-*` packages have been updated to v2 which includes [breaking changes](https://woodpecker-ci.org/docs/next/migrations#200).
 
 - `services.nginx` will no longer advertise HTTP/3 availability automatically. This must now be manually added, preferably to each location block.
