In the previous version, the newly merged Drude codes caused ForceBalance to crash when using the SMIRNOFF force field. This is now fixed. The Gromacs version has been pinned in the GitHub Actions CI (though most Gromacs tests are still skipped because there is no double precision builds as of now). molecule.py now uses importlib when available, in an ongoing effort to reduce the number of warnings when running tests.

Many additions to the code, including: (1) Objective function for experimental density of water. (2) OpenMM interface for evaluating interactions in OpenMM, and reading / writing XML files. (3) Internal test case (006) which should run correctly without any external software. There is also an OpenMM interface for reading and writing XML files, and evaluating the interactions using OpenMM.

Old force matching code (ForTune) developed by Lee-Ping Wang and Jiahao Chen at MIT. It has some features not ported over to ForceBalance yet, for example the self consistent parameterization cycles.
