Release of Open Babel 2.3

As announced by Geoff on the Open Babel mailing lists:
I am very happy to finally announce the release of Open Babel 2.3.0, the next major release of the open source chemistry toolbox.

Open Babel has been downloaded over 160,000 times and is used in over 40 projects.

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, Spectrophore descriptor generation, 2D depiction, improved 3D coordinate generation, conformer searching, and more. Many formats are improved or added, including CIF, PDBQT, SVG, and more. Improved developer API and scripting support and many, many bug fixes are also included.

What's new? See the full release notes.

See the new user guide.

See the updated developer documentation.

For more information, see the project website.

I would like to personally thank a few people for extra effort in improving this release. In alphabetical order Chris Morley, Noel O'Boyle, Tim Vandermeersch, and Silicos NV, which donated their Spectrophore(TM) framework to Open Babel 2.3.

This is a community project and we couldn't have made this release without you. Many thanks to all the contributors to Open Babel including those of you who submitted feedback, bug reports, and code.
