  • Upgraded to the new InChI 1.02 release to produce standardized InChI and InChIKey output.
  • Fixed many stereochemistry errors when reading/writing SMILES. This is part of a larger project which will be finished in the 2.3 release.
  • Fixed compilation and installation on Cygwin and MinGW platforms.
  • Significantly improved aromaticity and Kekule bond assignment.
  • Improved 2D -> 3D coordinate generation
  • Improved coordinate generation using the --gen3d command-line operation
  • Improved performance for coordinate generation.
  • New --fillUC command-line operation for babel.
  • Fixes to pH-dependent hydrogen addition.
  • Added support for reading vibrational data from Molden, Molpro, and NWChem output files.
  • Updated atomic radii from recent theoretical calculations.
  • Fixed bug when reading gzip-compressed Mol2 or XML files.
  • Close files after an error. Fixes a bug with Pybel where files would remain open.
  • Many more bug fixes and small feature improvements. ==New File Formats== Import & Export:
  • Molpro input and output.

New in version 2.2.1 (June 1st, 2009)

  • Improved scripting interfaces, including Python 3 support and improved Java and C# support.
  • Added support for MACCS fingerprints. Thanks to the RDKit project.
  • Many fixes and enhancements to the force field code. In particular, the UFF force field implementation should handle many more molecules.
  • Improved 3D coordinate generation, particularly with ring fragments. You can give this a try with the obgen utility.
  • Fixed a variety of PDB import errors with atom types.
  • Added support for reading charges and radii from PQR file formats.
  • Added support for reading and writing unit cells in PDB formats.
  • New "output" file format for taking generic ".out", ".log", and ".dat" files and reading with appropriate file type based on contents. Currently works extremely well for quantum chemistry packages.
  • Added improved error handling and reporting when unable to load file formats.
  • Improved CIF file format support.
  • Many, many, many additional bug fixes and small enhancements.
