Version 1.8

Hello all,
Version 1.8 is here. This release focused on the CBCT/CatPhan module. Highlights include deprecating the CBCT class in favor of individual classes: CatPhan504, CatPhan503, CatPhan600. This was done for two reasons. 1) Each Catphan has slight differences that require a different solution and 2) users have taken CT scans with their CatPhans (good idea) but pylinac cannot determine the CatPhan model via the manufacturer anymore (bad), thus this has to be explicitly stated. The upgrade should be done via pip as I’m having some trouble with the conda packaging.
