This file describes changes in various CARAT versions.

  • X.Y (YYY-MM-DD)

    • CARAT has been moved to GitHub.
    • Many bugs were fixed, including crashes, wrong results, data corruption and purely cosmetic ones
    • The build system was replaced with a completely new one, which made it easy to enable additional compiler warnings, which helped track down bugs
    • The C source code for CARAT underwent a major overhaul; constructs from old C versions (so called K&R C) were modernized; countless compiler warnings were fixed; most turned out harmless, but a seizable number still lead us to discover and fix various bugs

  • 2.0 (2003-04-11)

    • The new function Graph calculates the graph of inclusions of a geometric class of space groups.
    • The new function KSubgroups calculates maximal klassengleich subgroups.
    • The new function KSupergroups calculates minimal klassengleich supergroups
    • The new function TSubgroups calculates maximal translationengleich subgroups.
    • The new function TSupergroups calculates minimal translationengleich supergroups.
    • Bugfixes have been made for Z_equiv, Name and Presentation.
    • Extract -r -D writes space groups directly into files.
    • Conv now also converts groups and converts to TeX.
    • Name -c gives the name of a (space-)group in a short form. The Hermann-Mauguin-Symbols can be calculated in dimension 2 and 3 now (Name -M).
    • Extensions/Vectorsystems -S writes representatives of the affine classes in files.
