  • It is now possible to use the OpenGL pipeline for rendering
  • Memory configuration options have been added
  • Improvements in assignment table display and
  • Improvements in the Drag&Drop assignment process

The possibility to employ the OpenGL rendering pipeline for the data improves the softwares performance on Linux systems significantly. Note that a graphics card, capable of OpenGL 1.5 is required. Most recent (and most older) graphics cards offer driver support for OpenGL.

The following bugs have been fixed:

  1. Multiplet ddd bug. This bug lead to incorrect calculation and display of coupling constants in the multiplet display routine.
  2. Draw parameter dialog fixed: A wrong limitation in spinner values caused the offset setting of peaks and multiplets to "stuck". Fixed.
  3. JCAMP loader for processed data got wrong # of datapoints. Fixed.

The 2.1 version is released for Microsoft Windows only: The Linux version is under development.
