0.2.0 Biopolymer Support and Toolkit Adoption

0.2.0 Biopolymer Support and Toolkit Adoption

This release targets biopolymer support alongside version of 0.11.0 of the OpenFF Toolkit. Interchange now serves as the backend for OpenMM System creation in ForceField.create_openmm_system as part of the toolkit API, which also added ForceField.create_interchange. For more details on changes to the toolkit, see the OpenFF Toolkit release notes.

• #312 Adds conversion from InterMol System objects.
• #316 Adds an experimental GROMACS parser.
• #230 Adds experimental exports to some Amber files (.inpcrd and .prmtop).

Bug Fixes

• #308 Fixes a bug involving duck-types NumPy types.
• #322 Fixes a bug in which the Amber driver would not work with some mainline OpenFF force fields.

See the documentation for more information.
