Adjusted the handling of isotopes in the CIP algorithm to match the latest Hanson paper.Corrected issue where an implicit hydrogen and explicit hydrogen on the same side of a double bond would not disqualify the stereochemical configuration.Fixed the automatic updating of cis/trans stereochemical configurations.Corrected issue where stereochemical configurations were not automatically resolving for meso centers.Added option to add PAIR headers to SDF file output in the Files panel.Added support for mmCIF, BinaråIF and PDBML.Perfect support for bezier curve objects in ChemDraw CDX/CDXML files.Better handling of cases where a bezier curve drawing is cancelled. The first intersect point's first anchor will now appear and be editable if the custom shape is closed. All micro edits can now be undone and redone. You are now able to change the locations of control points independently of their mirror, but the default behavior is to keep them symmetrical. Bezier curve editing has been vastly improved.Users now have control over the CIP ligand cutoff length.You may turn these double bond configurations back on in the Functions panel. Double bonds in ring sizes of 7 or smaller are no longer designated stereochemical configurations by default, as designated by the IUPAC Blue Book 2013.Stereochemistry is preserved for these centers. Allene and cumulene coordinates are now properly assigned by the 2D structure cleaning function.There is a style to change M/P displays to Ra/Sa instead.

Full support for allene and cumulene stereochemistry, both for odd numbers of bonds (E/Z) and even numbers of bonds (M/P).menu item with no reaction selected, and a form will appear for you to input the typed chemical equation. Simply select the Reaction>Stoichiometry. Stoichiometry tables can now be generated from typed chemical equations, in addition to drawn chemical reactions.Full support for InChI stereochemistry, including allenes and cumulates. Updated InChI support to the current v1.06.There are two new options as well: (1) to enable/disable chain replacement nomenclature (on by default) and (2) to allow a minimum of 2 replacements (3 required by default). Excellent IUPAC naming support for chain replacement nomenclature.ChemDoodle 2D v11.8 includes significant improvements to many features, including excellent chain replacement nomenclature in IUPAC naming, support for allene/cumulene stereochemistry, improved bezier curve tools, current InChI support and more file options.
