The support for Japanese chemical names found in Japanese legal documents has been vastly improved.

Some syntaxes for benzofused ring systems were not supported.

The support for functional groups containing Selenium and Tellurium atoms has been improved.

Chain ester names used as substituents are now recognized.

All locants are now supported in tryptamine.

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.

The numbering of flavanone has been fixed.

Multiple custom dictionaries can be specified using the 'dict' format option: dict=<dictionary_path_1>;<dictionary_path_2>

The 'systematic' name format option does not disable the conversion of other name types anymore.

Names containing the keyword "substituted" are now supported, for instance: "2,4-disubstituted pyridine".

More syntaxes for carbon count in homology groups are recognized, for instance "(C1-6) alkyl".

The "Heterocyclyl" homology group is now supported.

Fix new OCR error in Japanese.

CAS Registry Numbers can now be converted when entered with extra whitespace before or after the number. This is especially useful when using copy-paste in end-user applications.

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.

Esters of nitric acid were imported with a radical instead of the C-O bond.

Some additional OCR error correction is performed in Chinese.

Some lists of names improperly separated lead to extremely long processing time.

β-alanine wrongly had a chiral stereocenter.

The file size of the naming component has been reduced by 10%, leading to reduced startup time in the applet.

Japanese names with fullwidth full stop characters were not supported.

Some E/Z and R/S stereodescriptors were not honored correctly.

Some more rarer acids are now supported, including those based on an Antimony atom.

Names containing the "sulfonato" prefix were converted incorrectly.

Japanese names containing the '=' separator character (for instance in esters) were not supported.

Support was added for acetimidamides and the imidamido suffix.

Failures from a custom naming webservice are now reported as an exception, to make it easier to solve misconfiguration of the service.

Conversion of systematic names is improved by supporting more functional groups.

Added support for the olato suffix in inorganic nomenclature.

Parent homology groups such as alkyl or hydroxyalkyl are now generated with an attachment point.

Custom name to structure webservice and CAS number resolution now try to use the system HTTP proxies, when available.

Naming webservice URLs can now contain a [DOMAIN] parameter that get replaced by the Windows domain name of the machine, or by the network domain name on non-Windows computers. This information can be used by the webservice, for instance for simple access control or user-based customization of the result.

Japanese and Chinese names with full-width curly braces were not supported.

Corporate IDs (registry numbers) can be converted using the API and class chemaxon.naming. n2s .DatabaseNameConverter.

Support for organo-metallic names was extended.

Support for CAS names was improved.

Halonium ions are imported correctly.

Substituted ferrocene and analogues are now supported.

CAS number conversion and naming webservice calls could run for a long time or even not return if the webservice was not responsive.

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.

Additional OCR error correction is performed.

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.
