Qalculate! 4.1

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, physical constants, symbolic calculations (including integrals and equations), arbitrary precision, uncertainty propagation, interval arithmetic, plotting, and a user-friendly interface (GTK, Qt, and CLI).

General changes:

• Use non-breaking narrow space as digit separator in reasonably short numbers, and between quantity and unit
• Update value of austronomical unit
• Fix segfault (when compiled with -D_GLIBCXX_ASSERTIONS) with local digit grouping when separator is empty (e.g. with ignore locale)
• Fix freezes and crashes with extrememly large vectors and matrices
• Fix segfault (when compiled with -D_GLIBCXX_ASSERTIONS) in matrix multiplication
• Minor bug fixes and feature improvements

GUI changes:

• Add option to show only parsed or entered expression, or both, in history
• Add option to clear expression history
• Do not add duplicate results to history
• Improved result copying, with proper html format and ASCII option
• Do not replace *, -, / with Unicode operators if cursor is within quotation marks (apply same principles on paste)
• Improve window focus retrieval method on Windows
• Improve appearance of icons with display scaling (Qt)
• Fix display of result with quoted symbol in history (GTK)
• Improvements and fixes for interaction with history (GTK)
• Do not change result color when window loses focus (GTK)
• Fix completion visible after expression cleared with key repetition (GTK)
• Do not perform automatic (continuous) conversion, from conversion view, if result contains no unit (GTK)
