## 1.0.0 - 2026-09-06

### Added

- Added configurable Diffie-Hellman parameter generation for one or more key sizes.
- Added global configuration options for temporary and persistent DH parameter directories.
- Added support for simple service definitions using the `service:owner` format.
- Added extended service definitions for per-service DH parameter deployment, destination ownership, and file permissions.
- Added support for both system-wide systemd services and per-user `systemctl --user` services.
- Added support for rootless container service units by executing user service actions with the configured service owner and `XDG_RUNTIME_DIR`.
- Added systemd state inspection through `LoadState`, `ActiveState`, `SubState`, and `Type`.
- Added automatic restart of active units after a successful optional service-specific DH parameter synchronization.
- Added automatic execution of inactive or failed `Type=oneshot` units after a successful DH parameter update.
- Added explicit validation and error reporting for missing users, missing units, unavailable user managers, incomplete service definitions, missing DH files, and failed file operations.
- Added secure, explicit ownership and permission handling for created target directories and deployed DH parameter files.
- Added cleanup and failure handling for temporary DH parameter files and the global synchronization step.

### Changed

- Changed service handling so that service-specific DH parameters are deployed before a service is restarted or a one-shot unit is started.
- Changed unit validation to distinguish missing services from inactive, failed, active, and transitional unit states.
- Changed reporting for per-user services to show the configured owner consistently for both status checks and service actions.
- Changed configuration parsing to preserve compatibility with `user.group` ownership syntax while converting it to `user:group` for `chown`.

### Fixed

- Fixed misleading success messages for services that do not exist on a host.
- Fixed the possibility of creating or synchronizing DH parameters to a configured target path when the corresponding systemd unit is missing.
- Fixed malformed error-handling blocks around destination-directory creation and DH parameter copy operations.
- Fixed validation of the configured `user.group` ownership field.
- Fixed user-service restart handling so that active `systemctl --user` services are restarted as their configured owner.
- Fixed handling of active `Type=oneshot` units with `SubState=exited` by using `ActiveState` for action decisions.
