2.0.01 Apr 2026
Highlights
- New plugin system will load menu commands, input generators, file formats, energy and electrostatic models, including installation of any required libraries and tools using [`pixi`](https://pixi.prefix.dev/latest/installation/) on Mac and Windows. (Highly recommended on Linux too)
- New plugin install window and index, including over 20 plugins (and growing)
- Faster geometry optimizations ~50% faster on all models, and up to 5-10x faster on large molecules using UFF.
- Added a faster protocol for using external energy models, including ML potentials, XTB, and more.
- Added a simple molecular dynamics mode to the AutoOpt tool, including with energy models.
- Improved ORCA input generator, including syntax highlighting
