Breaking Changes This is the last release including official support for Python 3.5. It will likely work for some time but mBuild will not be tested on Python 3.5 during development. Features * Residue names can optionally be inferred from compound names in conversion to ParmEd (475) * Custom cross-interactions (NBFIXES in ParmEd jargon) can now be written to LAMMPS data files (456) * The LAMMPS writer now prints helpful comments to more verbosely describe which atom types are associated with each potential (535) Maintenance * Some stylistic changes were made as suggested by various linters (522) * Appveyor now tests on Python 3.6 (520) Documentation * Installation docs were updated to explicitly list supported Python versions (532) * A comment pointing to the `glozter` Anaconda channel has been updated to point to `conda-forge` (534) Miscellaneous * Some tests depending on `foyer` are now properly skipped when it it not installed (521) * Some examples were updated in accordance with their new structure as internal recipes (536, 538)
Features * A plugin or "recipe" architecture has been added to allow external modules to be imported inside of mBuild (501) * Python 3.6 is now explicitly supported and tested (518) Maintenance * A contributor's guide (500) and `.github` issue & pull request templates (498) have been added * A redundant and unused block of code was removed (515) * The `glotzer` and `bioconda` channels, which are now obsolete in this scope, have been dropped (516)
Breaking Changes * When writing hoomdxml files, units will now be in kJ/mol & nm instead of kcal/mol & ang, so particle positions will differ by a factor of 10. Features * A `to_networkx` function was added to convert the hierarchy of a compound to a graph (484) * Packing functions now use XYZ files while running PACKMOL, bypassing some issues with PDB files (422) * When saving hoomdxml files, `auto_scale=True` will scale reference units from max forcefield parameters. (488) Maintenance * Switched to codecov for code coverage testing (485) * Some dependencies accidentally missing in earlier PRs were cleaned up (493) Bugfixes * `update_coordinates` now behaves well when passed an XYZ file or operating on simple hierarchies (496) * Internal conversion from ParmEd structures to HOOMDXML files was improved (463, see above)
