What’s new from 1.99

• Bond order typing is performed when importing from formats with no notion of bonds (quantum chemistry programs, XYZ, etc.). -Now better conforms to the ISO C++ standard, should compile on most modern C++ compilers.
• Improved test suite, including “roundtrip” testing, ensuring more accurate translations.
• Support for the Chemical Markup Language (CML) and other file formats. (see below)
• Improved PDB support – should read PDB files more accurately and hew closer to the current PDB standard for export.
• Improved Gaussian input generation.
• Added support for the Chemical MIME standards, including command-line switches.
• Added support for using the babel program as a pipe for a “translation filter” for other programs.
• Can add hydrogen atoms based on pH.

• Fixed a wide variety of bugs in various file formats.
• Faster SMARTS matching and some overall speedups across the program.
