Avogadro 1.95.0

Changes

We are pleased to announce the latest release of Avogadro, including piles of bug fixes and feature enhancements.
Thanks to many for suggestions, bug reports, and discussions.

This release includes many new features, including new protein ribbon / cartoon renderings and the new "Layer"
system as part of Google Summer of Code by @serk12.

Draft developer documentation can be found at https://two.avogadro.cc

If you have comments or suggestions, please join us at https://discuss.avogadro.cc and as always, help and contributions
in many forms are very welcome, particularly if you'd like to help with user documentation.

We anticipate several more releases over fall 2021 as we finish up our 2.0 release.
