v1.2.0

• Improvements:

  • Euphonic now tests on Python 3.11
  • Euphonic now provides PyPI wheels for Python 3.11

• New features:

  • You can now perform linear interpolation of phonon frequencies and
    eigenvectors with the Brille <https://brille.github.io/stable/index.html>_
    library using the new
    euphonic.brille.BrilleInterpolator object. This should provide
    performance improvements for large unit cells which require the
    dipole correction.
  • There is a new command-line tool euphonic-brille-convergence to
    assist with choosing the BrilleInterpolator.from_force_constants
    arguments to achieve the desired accuracy.
  • Brille interpolation can be accessed from the euphonic-powder-map tool
    using the new --use-brille, --brille-grid-type, --brille-npts
    and --brille-npts-density arguments.
