 - [PR #1525](https://github.com/openforcefield/openff-toolkit/pull/1525): Some unrelesed force fields previously accesible from `"openff/toolkit/data/test_forcefields/"` are no longer implicitly available to the `ForceField` constructor.

 ### Improved documentation and warnings
 - [PR #1498](https://github.com/openforcefield/openff-toolkit/pull/1498): Improved documentation for `Molecule.remap()`, `Molecule.from_smiles()`, and `Molecule.from_mapped_smiles()`, emphasizing the relationships between these methods. In particular, the documentation now clearly states that `from_smiles()` will not reorder atoms based on SMILES atom mapping.
 - [PR #1525](https://github.com/openforcefield/openff-toolkit/pull/1525): Improves reporting failures when loading force fields.
