- Optimized window layout in tools Combinatorics, Quadratic equation and Rule of three for better displaying of the result values and error texts, and to make more room for longer translated texts in some languages
- If no valid language is specified in the settings.ini file, the program will try to use a language file according to the users system language
- Added Hungarian translation by Zsolt Nemeth
- Added Ukrainian translation by Bonsai
- Fixed manual file html validity errors in some translations
