  • Other:
  • New utility gwyddion-thumbnailer creates SPM file thumbnails for desktop environments. In this release, GNOME, XFce and KDE4 are fully supported with thumbnails created on-the-fly. In other TMS-conforming environments the thumbnailer must be run manually to batch-create the thumbnails.

  • libgwyddion: libgwyddion/gwymathfallback.h is the preferred header to define the math fallback functions now, for compatibility libgwyddion/gwymath.h works too.
  • libgwyddion: All the math fallback functions are public inline functions (not macros) named gwy_math_fallback_foo(), so it's possible to take their addresses if necessary.
  • libgwyddion: Defining GWY_MATH_NAMESPACE_CLEAN before including gwymathfallback.h prevents the definition of unprefixed aliases such as cbrt for math functions not provided by the platform (gwy_math_fallback_cbrt() remains available). Use in the case of possible name clash.
