v0.7.0

• Added full support for conjunctive nomenclature e.g. 1,3,5-benzenetriacetic acid
• Added basic support for CAS names
• Added trivial poly-noncarboxylic acids and more trivial carboxylic acids
• Added support for spirobi/spiroter/dispiroter and the majority of spiro(ring-locant-ring) nomenclature
• Indicators of the direction that a chemical rotates plane polarised light are now detected and ignored
• Fixed many cases of trivial names being interpreted systematically by adding more trivial names and detecting such cases
• Names such as oxalic bromide cyanide where a halide/pseudohalide replaces an oxygen are now supported
• Amino acid ester named from the neutral amino acid are now supported e.g. glycine ethyl ester
• Added more heteroatom replacement terms
• Allowed creation of an OPSIN parse through NameToStructure.getOpsinParser()
• Added support for dehydro - for unsaturating bonds
• Improvements to element symbol locant assignment and retrieving appropriate atoms from locants like N2
• OPSIN's SMILES parser now accept specification of number of hydrogens in cases other than chiral atoms
• Mixtures specified by separating components by semicolonspace are now supported
• Many internal improvements and bug fixes

v0.6.1

• Counter ions are now duplicated such as to lead to if possible a neutral compound
• In names like nitrous amide the atoms modified by the functional replacement can now be substituted
• Allowed number for specifying superscripts
• Vocabulary improvements
• Added quinone suffix
• Tetrahedral sulfur stereochemistry is now recognised
• Bug fixes to fix incorrect interpretation of some names e.g. triphosgene is now unparseable rather than 3 x phosghene, phospho has different meanings depending on whether it used on an amino acid or another group etc.

v0.6.0

• OPSIN is now a mavenised project consisting of two modules: core and inchi. Core does name -->CML, inchi depends on core and allows conversion to inchi
• Instead of CML an OpsinResult can be returned which can yield information as to why a name was not interpretable
• Added support for unlocanted R/S/E/Z stereochemistry. Removed limit on number of atoms that stereochemistry code can handle
• Added support for polymers e.g. poly(ethylene)
• Improvements in handling of multiplicative nomenclature
• Improvements to fusion nomenclature handling: multiplied components and multi parent systems are now supported
• Improved support for functional class nomenclature; space detection has been improved and support has been added for anhydride,oxide,oxime,hydrazone,semicarbazone,thiosemicarbazone,selenosemicarbazone,tellurosemicarbazone,imide
• Support for the lambda convention
• Locanted esters
• Improvements in dearomatisation code
• CML output changed to being CML-Lite compliant
• Speed improvements
• Support for greek letters e.g. as alpha or $a or α
• Added more infixes
• Added more suffixes
• Vocabulary improvements
• Systematic handling of amino acid nomenclature
• Added support for perhydro
• Support for ylium/uide
• Support for locants like N-1 (instead of N1)
• Fixed potential infinite loop in fused ring numbering
• Made grammar more lenient in many places e.g. euphonic o, optional sqaure brackets
• Sulph is now treated like sulf as in sulphuric acid
• and many misc fixes and improvements
