OpenMM is a toolkit for molecular simulation using high performance GPU code.

This is a patch release. It contains a small number of bug fixes, as well as changes to enable two significant additions to the supported platforms.

First, this release provides preliminary support for ARM based Macs. The support has not been extensively tested and should be treated as beta quality. Please try it out and let us know if you encounter any bugs while using it.

Second, we are now providing conda packages for use with Pypy. This is an alternate Python interpreter that uses just-in-time compilation to provide much faster execution than CPython. You can create a conda environment that uses Pypy with the command

conda create -c conda-forge --name pypy pypy
