The common names of 220 more pesticides have been added to the dictionaries.
Some CAS Registry Numbers that were converted to a structure with only aliases representing the amino-acid 3 letter codes, for instance 98059-61-1. The underlying chemical meaning of each amino-acid is now automatically added when absent.
The common name dictionary has been significantly updated and extended with 30 thousand new names and synonyms.
For CAS Registry Numbers(R), when one of the remote webservices is unavailable, the conversion will not block for as much time as before.
Some CAS Registry Number lookups were incorrectly cached in version 18.30.
Some CAS Registry Numbers were converted to invalid structures in version 18.30.

The common names of 5 thousand herbicides and pesticides are now included in the dictionary.
Names containing a 'dehydro' corresponding to a triple bond are now supported.
Names containing the term 'carboaryl' are now converted using the corresponding homology group instead of the broader group 'aryl'.
Longer common names are now supported.
CAS Registry Numbers with invalid check digits are now reported as errors with a specific error message. This happens in particular for CAS Numbers which have been entered with a typo.
String of the form X-XX-X were wrongly recognized as CAS Registry Numbers.
The common name dictionary is extended to include INCI names (International Nomenclature of Cosmetic Ingredients).
The new nameField format option can be used to set which field/property stores the original name (instead of the molecule title).
Some nucleosides and nucleotides had incorrect stereochemistry.
CAS number conversion was failing since version 17.9 in .NET 32 bit applications.
The homology group haloalkyl is now represented more accurately.
More ASCII syntaxes are supported for superscript numbers in bridged ring system names.
The name format was not detected for names contain the special "soft-hyphen" character.
Ring fusions involving multiple bonds are now supported.
The traditional steroid numbering of cyclopenta[a]phenanthrene is now supported in addition to the IUPAC numbering.
Capital S- is now understood as sym- where appropriate.
Names with added space characters are better recognized.
More disconnected structures are now supported, for instance pyridine acetate.
Names separated by ';' were not detected from arbitrary text formats. This affected in particular JChem for Excel.
Some element names were wrongly detected and represented as structures.
The support for functional groups containing Selenium and Tellurium atoms has been improved.
Support has been added for more cases of accidental spaces in name (often caused by OCR), such as "m ethyl".
Support has been improved for parent names starting with a symbol, such as s - and as -indacene.
Additional OCR error correction allows to convert more names from scanned documents and patents.
Spiro names that mistakenly lack a prime on the second spiro atom locant are now automatically fixed.
The accuracy in the conversion of Chinese names to structures is improved.
Several improvements increase the conversion of systematic names.
Names with small typographical errors, such as added spaces or missing dashes, are better supported. This especially improves the extraction of names from lower quality sources, such as patent texts generated by OCR.
Some lists of names improperly separated lead to extremely long processing time.
OCR error correction is improved.
Lowercase d- and l- stereo-descriptors are now interpreted as D- and L-, since names are sometimes (wrongly) converted to all lowercase. This is correct most of the time since the old usage of d- and l- for optical activity (dextrorotatory and levorotatory) is out of use and replaced by (+) and (-).
Names with (r) and (s) pseudo-asymmetric stereo centers are now fully supported.
Chinese name to structure coverage was improved by about 3 percentage points.
Some names designating multiplied fused systems failed to be converted.
Some names referring to the locant of spiro atoms were failing to be converted to structure or were missing stereochemistry on those atoms.
Some partially saturated polyacenes and polyaphenes were not supported.
Some Chinese and Japanese chemical names with punctuation characters were were not supported by the automatic format recognizer.
Double bonds in large rings that are part of fused systems had unknown stereochemistry. They now have cis stereochemistry.
Some substituents separated by a space from an acid parent were wrongly interpreted as esters.
The naming webservice was not working in the applet.
