- The upgrade to Mathematica 12 broke several features. These have been fixed or workarounds used
- Formating of the exchange multiplets has been improved
- Formatting of the stationary vector groups has been updated for clarity and to try to reduce confusion with the isotropy groups of Isodistort (amongst the differences, here I use the group of Gk only and not physically irreducible representations)
- An error in the phasing k vector was fixed. This would have impacted some cases where the propagation vector was rotated in order to match Kovalev’s selection
