We are pleased to announce the latest release of Avogadro, including piles of
bug fixes and feature enhancements.

As part of the release, we've made it easier to download scripts and data,
including new input generators, molecule fragments, and build and analysis
commands. These scripts make it much easier to integrate Avogadro with many
open source chemistry Python tools, including RDKit, ASE, etc.
