What’s New in Astropy 4.1?


Astropy 4.1 is a major release that contains bug fixes and new features since the 4.0.x series of releases.

In particular, this release includes:

  1. Support for the -TAB algorithm in FITS WCS as described in WCS Paper III . In particular, astropy.wcs will be able to support -TAB in WCS if already defined in the astropy.io.fits.HDUList object.

  2. Support for units on otherwise unitless models via the Model.coerce_units method.
