v0.2.5¶

Fix symmetry-adapted displacements for noisy and lower-symmetry inputs [#27]
- Require spgrep>=0.3.3 for robust treatment for selecting symmetry-adapted bases

v0.2.4¶

Fix get_translational_subgroup() for Gamma point

v0.2.3¶

Initial release to PyPI

Calculate representation matrices and irreps formed by phonon eigenmodes
Calculate isotropy subgroups of irreps of space groups on the fly
Generate modulated structures in selected order-parameter directions of isotropy subgroups
