As a preparation for the next major update, we've refactored the update system and fixed two bugs.
- New update system that checks the requirements before upgrading to a new major version.
- Fixed a bug that caused special characters to display incorrectly in the design settings (#66, reported by @Silbad).
- Fixed wrong return values from the CLI commands (#71, reported by @Digi92).
- Updated the translations for the backend.
