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, Qt, and CLI).
Changes:
- Fixes and improvements for expression field below history
- Option to show expression status in status bar
- Option to change the default currency
- Customizable status bar font
- Colorize icons if the button text color differs visibly from the default icon color
- Improve interpretation of function expressions with x, y, or z in object names (e.g. "x year"), or within quotation marks

- Show error when function or variable disabled by "--disable-insecure" is used (libqalculate)
- Fix infinite loop during factorization on Windows (libqalculate)
