This page lists the recent changes in versions of PyPhot.

[November 11, 2025]

major refactoring of the codebase: remove code duplication due to the split astropy vs. pint
- import pyphot.astropy as pyphot replaced by import pyphot (default backend is ‘astropy’)
- set units with pyphot.config.set_units_backend('astropy') or pyphot.config.set_units_backend('pint') (default is ‘astropy’)
adapters to interface transparently with varied unit frameworks (e.g., astropy.units, pint) - pyphot.config.set_units_backend() to switch between different unit frameworks - default priority is astropy, pint, ezunits[legacy]

added type hints (incl. pyphot.typing)
- hint typing checked with pyright, not mypy.
a more robust and general unit ensuring decorator pyphot.units_adapter.enforce_default_units() which also updates the docstring accordingly
vega flavor can now be switched globally
- use pyphot.config.set_vega_flavor() (see Details on the internal Vega reference spectra documentation)
- remains available at the filter definition (since v.1.7.0)
internal simpletable removed in favor of pandas
- pyphot.io for ascii, fits, hdf5, and votable adapted from mfouesneau/simpletable
removed astropy dependency for SVO interface (still currently needed for fits)
more comprehensive unit tests (coverage > 70%)
updated documentation, pyphot Quickstart, and More examples with Pyphot
