The Lexichem name parsing routines now handle a small number of structural abbreviations when parsing names. For example, it can now handle names like ‘3-CF3-5-NO2-benzoic acid‘. The usual improvements in name parsing, including more entries for common names in the Lexichem dictionary. Support for names containing multiple explicit hydrogen locants, such as ‘pyrimidine-2,4(1H,3H)-dione‘ and ‘2,4(1H,3H)-pyrimidinedione‘.
A serious bug that could cause a core dump when naming thioperoxoic acids has been fixed. The performance of compound naming has been improved. The usual improvements in the names generated (following the IUPAC standards more closely).
