- `services.soju` now has a wrapper for the `sojuctl` command, pointed at the service config file. It also has the new option `adminSocket.enable`, which creates a unix admin socket at `/run/soju/admin`.

- `services.stalwart-mail` uses the legacy version 0.6.X as default because newer `stalwart-mail` versions require a [manual upgrade process](https://github.com/stalwartlabs/mail-server/blob/main/UPGRADING.md). Change [`services.stalwart-mail.package`](#opt-services.stalwart-mail.package) to `pkgs.stalwart-mail` if you wish to switch to the new version.

- `services.stalwart-mail` has been renamed to `services.stalwart` to align with upstream re-brand as an e-mail and collaboration server. Other notable breaking changes to module:

  - `systemd.services.stalwart` owned by `stalwart:stalwart`. The `user` and `group` are configurable via `services.stalwart.user` and `services.stalwart.group`, respectively. By default, if `stateVersion` is older than `26.05`, will fallback to legacy value of `stalwart-mail` for both `user` and `group`.

  - Default value for `services.stalwart.dataDir` has changed to `/var/lib/stalwart`. If `stateVersion` is older than `26.05`, will fallback to legacy value of `/var/lib/stalwart-mail`.

- Ethercalc and its associated module have been removed, as the package is unmaintained and cannot be installed from source with npm now.

- `services.cgit` before always had the git-http-backend and its "export all" setting enabled, which sidestepped any access control configured in cgit's settings. Now you have to make a decision and either enable or disable `services.cgit.gitHttpBackend.checkExportOkFiles` (or disable the git-http-backend).
