CHANGELOG.md

@@ -9,6 +9,7 @@ Changelog
 * Fixed ``--stiffen-rotamers`` placing the minimum of every stiffened dihedral at 0 degrees (cis), which eclipsed the ghosts with the anchor and stacked multiple ghosts on the same bridge. The minimum is now the dihedral angle measured in the end state where the ghosts are physical [#19](https://github.com/OpenBioSim/ghostly/pull/19).
 * Added ``--single-well-anchors`` and ``--k-single-well`` to replace surviving anchor dihedrals with a single-well cosine potential whose minimum is the geometry of the end state where the ghost is physical. Multi-well anchors, e.g. the n=2 term of a dummy hydrogen on a carbonyl oxygen, can trap ghosts in an alternative well at intermediate lambda, giving hysteresis between independently equilibrated windows. Anchors with zero force constants or an ill-defined reference dihedral are left unchanged. (Default: False, 5 kcal/mol) [#19](https://github.com/OpenBioSim/ghostly/pull/19).
 * Record the options used for each modification in a ``ghostly_options`` property on each modified molecule, and raise an error when modifying a system that has already been modified, unless ``--force`` is used. Forced modifications are applied on top of the existing ones [#20](https://github.com/OpenBioSim/ghostly/pull/20).
+* Added support for Python 3.13 and 3.14, and dropped support for Python 3.10 and 3.11.
