cartoon_gap_cutoff: draw dashed cartoon over gaps of size < cartoon_gap_cutoff
auto_show_classified: When loading a file, show cartoon for polymer, sticks for organic, and spheres for inorganic molecules (Setting > Auto Show… > … by Classification)
ignore_case_chain setting (ignore_case=1 default restored in 1.8.0.5)
collada_background_box (off by default, previous versions unconditionally created a large box to mimic the scene background color)
File Import/Export
support atom name/resn/segi with more than 4 letters (e.g. from CIF files)
MOL2
loading
improve resn reconstruction from subst_name
improve formal_charge guessing
export
write SUBSTRUCTURE record for chain support
MAE loading: sort atoms
amber topology loading: set all bond orders to 1 instead of 0
Misc
