Qalculate! is a multi-purpose cross-platform desktop calculator. It is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a user-friendly interface (GTK+ and CLI).

List of main changes:
- Redesigned keypad with a lot more functionality.
- Multiline expression entry with undo/redo.
- Alternative simplified function creation dialog.
- Percentage calculation tool.
- Binary installer for Microsoft Windows.
- Date functions have been rewritten and now support much larger numbers.
- Trigonometric functions with angle unit other than radians have been fixed.
- Functions with more than one argument can now also be applied to the RPN stack.
- New functions: airy(), arg(), besselj(), bessely(), conj(), digamma(), erf(), erfc()
- Many minor enhancements and bug fixes.
