We're still working... @geoffhutchison.net reports on new speedups coming in v2.1 scheduled for June 02 (6/02 in the states 😉) - 20-25x faster orbital and density calculations - 6-8x faster geometry optimizations using an adaptive FIRE+L-BFGS method discuss.avogadro.cc/t/may-2026-d... #compchem

One week of Avogadro 2.0 highlights - and we're just getting started… Download: avogadro.cc/install/ Join the community: discuss.avogadro.cc Thanks to everyone who helped make this release happen. Open science is a team effort! Got ideas on where to go next? 🧪 ⚗️ #opensource #openscience #compchem

Avogadro 2.0 isn't just a viewer and editor — it's an extensible platform for chemistry A plugin system lets you add ML & electrostatic models, new builders and tools. Already over 20 available… Build the tools you need: avogadro.cc/develop/plug... #avogadro #openscience #compchem #opensource

Sometimes you just want to see a molecule move. Run a quick MD simulation without leaving Avogadro — no scripts, no setup. The new auto-optimize tool includes a dynamics mode. Watch it move in real time. Great for teaching. Great for intuition. Just fun to watch. #openscience #compchem #opensource

Visualize molecular orbitals and electron density easily with Avogadro 2.0. Volumetric rendering of orbitals, plus van der Waals, solvent-accessible and solvent-excluded surfaces for biomolecular work. See the chemistry, not just the atoms. #compchem #openscience #opensource

Inorganic and organometallic chemists — Avogadro 2.0 is for you... A new template tool lets you build octahedral, tetrahedral, and other complexes in seconds. Click to add functional groups. Avogadro also detects symmetry and displays symmetry elements #compchem #openscience #opensource

Avogadro 2.0's rendering was rebuilt for modern GPUs. Smooth even with tens of thousands of atoms. Real-time shadows and ambient occlusion give depth and clarity — and a new layer system lets you hide solvent, toggle styles, and focus on what matters. #opensource #openscience #compchem

No fooling, Avogadro 2.0.0 is finally here! Rebuilt from the ground up: fast modern rendering, improved stability, designed for the next generation of molecular, biomolecule, and materials research & education. 🧪 ⚗️ avogadro.cc/install/ discuss.avogadro.cc #opensource #openscience #compchem

Something big is coming on 1 April – and no, it's not a joke. 🧪 ⚗️ #opensource #openscience #compchem

Avogadro 2.0 drops April 1st — and no, that's not a joke! 🧪⚗️ Now's the perfect time to help improve translations before release. Every language matters for chemistry worldwide. #opensource #openscience hosted.weblate.org/engage/avoga...

Coming soon in Avogadro 2.0… 👀 Loadable energy plugins, including ML (ANI, AIMNET, MACE …) and XTB (GFN-FF, GFN1, GFN2) Easy to add .. what models would you want to see?

Coming soon... electrostatic model plugins 👀 #openscience #compchem

Has @avogadro.cc helped your research? Teaching? As we prepare Avogadro 2.0 for release this spring, I'm hoping to feature some stories (and citations). #compchem #opensource #openscience ⚗️ Let me know: discuss.avogadro.cc/t/avogadro-s...

Avogadro Stories (for 2.0 Release)

As we finish up the 2.0 (final!) release, I’d like to feature some stories (and citations) about how Avogadro has shaped research and teaching. So if Avogadro has helped your research, please let me ...

discuss.avogadro.cc

It's 06-02, so a new release - v 1.103 Highlights include new volumetric rendering, faster orbital calculation, return of the peptide builder, new keyboard shortcuts to add functional groups and ligands, better support for open-shell orbitals, and much more... discuss.avogadro.cc/t/avogadro-1...

Obviously a lot is going on (gestures widely) Amid chaos, I cope by doing *something* -- anything. Lately, it's been coding for @avogadro.cc because it feels like some small change I can do myself For *years* I've wanted to show electron density volumes .. little clouds ☁️☁️ #compchem

We are aiming for a release of Avogadro 2.0 on 06-Feb (06/02 😉) If you are running into bugs or problems, please report them soon! #compchem discuss.avogadro.cc

We just passed 3M downloads worldwide! 🎉 🎉 Thanks to all our users - it's been a great start and we look forward to more great things to come! #chemsky #compchemsky

👀

We just uploaded a video showing off the new template tool, building up triphenyl phosphine oxide. You can easily add atoms with specific geometries, and click to add functional groups. We include over 150 with 2D previews. Suggestions always welcome: discuss.avogadro.cc youtu.be/RC4NZp6nnD8

Tested out some water clusters during lunch. - MMFF94 has point charges and hydrogen bonds - UFF does not (so water molecules push apart) At some point I'll add some simple dynamics… #compchem #compchemsky

If you've been wondering about the status of the AutoOptimize interactive optimization in Avogadro2 - coming later this month 👀

👀 Coming soon...

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...
