- The 2D coordinate generation can now optionally use templates when working with complex ring systems. We will continue to improve this functionality in future releases.
- There’s now a single function which allows you to calculate all available 2D descriptors for a molecule: Descriptors.CalcMolDescriptors()
- Support for working with organometallic molecules has improved: drawings of these structures are now better and there’s new code for switching back and forth between dative and multi-center views of the bonding in systems like ferrocene.
- The fingerprint generator code has been improved and expanded with the idea of allowing user to switch entirely to the new code for the supported fingerprint types: Morgan, RDKit, topological torsion, and atom pairs.
