+This new version introduces some major changes. In particular, it introduces
+the use of measured microphone and source directivities. This new feature
+allows to simulate more accurately real recording equipments. See the

the current default is ``False`` to match past behavior, but will be changed to
``True`` in the next release because the filters have less oscillations this way.
+- New parameter ``min_phase`` of class ``Room``. If set to ``True``, the band-pass
+ filters are designed as minimum phase filters.
+
- Simulation with measured directivity responses in SOFA format (limited file types) is
possible with the image source model.
+
+ - A flexible and extensible SOFA file reader with optional spherical interpolation.
+ - A small database of files is bundled, including the `DIRPAT database

+- Introduces a new class ``pyroomacoustics.directivities.Rotation3D`` to specify

- Adds `soxr `_ as a dependency since resampling
can often be necessary when working with SOFA files.
