We've got a new release 1.101, which should particularly fix some bugs with Windows and Mac, and of course a variety of new features. Highlights include support for constraints for geometry optimizations, tweaking bond lengths when changing elements, and more... discuss.avogadro.cc/t/avogadro-1...

Thanks to a suggestion from a user, we've been working on some tweaks to the draw tool... Now you can click on a hydrogen atom to change the element and the bond will grow longer or shrink as needed Coming soon to the next release (or in a nightly build)

To be clear, volumetric rendering of molecular orbitals, electron density, etc. will soon be available: discuss.avogadro.cc/t/volumetric... Colors are configurable...

What's this? 🤔 Working on something new... #opensource #compchem

We're starting off 2025 with a new release - 1.100 Highlights include new blur and fog rendering, faster orbital surfaces, return of the MO table, translucent balls-and-sticks, conformer properties, an improved molecular properties window, and more... discuss.avogadro.cc/t/avogadro-1...

We're finishing up a new release, but trying to track down some bugs 🪲 #compchem Some Windows users report Avogadro 1.99 won't even launch. If this is you and you're willing to test a new build, please let us know at discuss.avogadro.cc

I wrote up a 2024 Year in Review for @avogadro.cc 🧪⚗️ #opensource #chemsky In short, the community is amazing. Significant translations into 17 languages including 🇭🇷🇫🇷🇭🇺🇰🇷🇷🇴🇪🇸Tamil, 🇺🇦🇨🇳🇬🇪🇩🇪🇯🇵🇵🇹🇧🇷🇷🇸🇹🇷 .. and of course dozens of features and bug fixes discuss.avogadro.cc/t/2024-year-...

We've got a "Cyber Monday" special discount too! Download a nightly build today 🧪 #chemsky

In honor of Black Friday in the US, we've got a special discount! Use "Open Source" and you can get Avogadro 1.99 for free! Wait, you *never* need a discount code? It's #opensource and #openscience Visit two.avogadro.cc and discuss.avogadro.cc to see what we've been doing for Avogadro v2.

We're back with a new release! 🎉 Highlights include improved force field optimizations, faster surfaces & orbitals, vibration spectra plots, and new tool icons, plus dozens of bug fixes, features, and new script plugins discuss.avogadro.cc/t/avogadro-1...

As someone who went to grad school as an inorganic chemist, it gives me some pleasure to finally have a free tool to click-click-click assemble iron bipyridine complexes or Ziegler-Natta catalyst models in @avogadro.cc in about the same time it takes to build an organic compound. #chemsky 🧪

We're happy to announce v1.98, the latest beta of Avogadro2, including piles of new features and bug fixes, including support for 3Dconnexion devices on Windows and Mac #compchem Lots more - see: discuss.avogadro.cc/t/avogadro-1...
