I just heard version 11.3 of ChemDoodle 2D software has been released.

ChemDoodle 2D v11.3 is a feature update. The main new feature is expert IUPAC naming support for free radicals. Other major features include new image output sizing options with previews, and stoichiometry table options.

ChemDoodle 2D is a popular and extensively featured Chemical Drawing and cheminformatics software tool.
