Open Babel 2.3.0 was released on 2010-10-XX.

Release Notice

This release represents a major update and should be a stable upgrade, strongly recommended for all users of Open Babel. Highlights include a completely rewritten stereochemistry engine, 2D depiction, improved 3D coordinate generation, ..... Many formats are improved or added, including CIF, .... , and more. Improved developer API and scripting support and many, many bug fixes are also included.

What's New from 2.2.3

  • Completely rewritten stereochemistry perception, including support for tetrahedral, square planar, and higher-order stereochemistry.
  • Dramatically improved canonicalization algorithm (typically assigning different canonical SMILES).
  • 2D depiction, including SVG vector graphics generation.
  • New ChargeMethod API including support for partial charge assignment from Gasteiger, MMFF94, Qeq, QTPIE methods and plugin interface for adding more.
  • Improved 3D coordinate generation.
  • New conformer generation framework.
  • Improved user documentation.
  • Improved aromaticity / Kekule bond assignment.
  • Improved unit test suite using the CMake-based CTest program.
  • Improved support for crystallographic unit cells (e.g., in CIF format).
  • Improved UFF force field method, including hypervalent 5, 6, 7 and higher coordination numbers.
  • Support for the GAFF (Generalized Amber Force Field) method.
  • Support for reading geometry optimizations as multiple conformers from Gaussian, GAMESS-US, and other quantum chemistry packages.
  • Support for reading molecular orbital energies from quantum chemistry formats.
  • Several memory leaks fixed.
  • Fixed many compiler warnings.
  • Fixed support for MinGW and Cygwin environments.
  • Fixed bugs with Gaussian 09 output files.
  • Latest released version of the InChI library (1.0.3) generating standard InChI.
  • Many more bug fixes and small feature improvements.

Added Command-Line Operations

  • --unique: Only output unique molecules (as determined by InChI generation)
