Qalculate! is a multi-purpose cross-platform desktop calculator. It is simple to use but provides power and versatility normally reserved for complicated math packages, as well as useful tools for everyday needs (such as currency conversion and percent calculation). Features include a large library of customizable functions, unit calculations and conversion, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting, and a user-friendly interface (GTK+ and CLI).

- Option to hide left or right part of the keypad
- Replace fraction mode combo box with a single toggle button
- Disable prefixes by default in scientific, engineering, and pure modes, and change behaviour of composite modes when user changes separate options

- Split long numerical results in two lines and show bit position for binary number that does not fit in window
- Improved text layout in result
- Brazilian Portuguese and Spanish translations
- Fix Insert button in insert function dialog
- Examples in manual
- Improved exact simplification of roots (e.g. sqrt(2)-2/sqrt(2)=0) (libqalculate)
- Only apply negative exponents option to units, and always use negative exponents instead of division for unit expressions with only negative exponents (libqalculate)
- Support use of right arrow (including "->") as alternative to "to" for conversion (e.g. 5m->ft) (libqalculate)
- Use middle dot instead of multiplication x in unit expressions (libqalculate)
