.: 2017-07-24 :. Qalculate! version 1.0 released

Qalculate! version 1.0 includes the following changes:
  • Increased efficiency and stability. Slow calculations can in most cases now be terminated in a controlled manner and the application should no longer potentially crash when trying to calculate extremely large numbers.
  • Enhanced factorization.
  • Revised temperature unit handling.
  • Enhanced automatic unit conversion, including a new default mode which keeps original non-SI units if no better alternative (that uses fewer units and exponents) is found.
  • A long list of bug fixes and minor feature enhancements.
For a complete list of changes see the git logs for libqalculate and qalculate-gtk.
