• Register all available asdf extension manifests from asdf-wcs-schemas except 1.0.0 (which contains duplicate tag versions). [#469]
• Register empty extension for 1.0.0 to avoid warning about a missing extension when opening old files. [#475]

What's Changed

• Fix pixel scale formula used by iterative inverse by @mcara in #423
• refactor for Tox 4 by @zacharyburnett in #428
• Improve stability of SIP fitting. Fix constant term - CRPIX - in SIP by @mcara in #427
• use canonical name of RTD config and enable nitpicky mode to catch broken links in docs by @zacharyburnett in #430
• add downstream tests for JWST and Roman calibration pipelines by @zacharyburnett in #415

Full Changelog: 0.18.2...0.18.3

GWCS v 0.18.2

GWCS v 0.18.2 is a bug fix release to support the JWST pipeline.

• Corrected the reported requested forward SIP accuracy and reported fit
  residuals by to_fits_sip() and to_fits(). [#413, #419]

• Fixed a bug due to which the check for divergence in _fit_2D_poly() and
  hence in to_fits() and to_fits_sip() was ignored. [#414]

GWCS 0.18.1

GWCS 0.18.1 is a maintenance release.

GWCS 0.18.0

GWCS v 0.18.0 (2021-12-22)

Bug Fixes

Updated code in region.py with latest improvements and bug fixes from stsci.skypac.regions.py [#382]

New Features

Enabled CompoundBoundingBox support for wcs. [#375]
Moved schemas to standalone package asdf-wcs-schemas. Reworked the serialization code to use ASDF converters. [#388]

GWCS 0.17.1

• Fixed a bug with StokesProfile and Quantities.

GWCS 0.17.0

New Features

• wcs_from_points now includes fitting for the inverse transform. [#349]
• Generalized WCS.to_fits_sip to be able to create a 2D celestial FITS WCS from celestial subspace of the WCS. Also, now WCS.to_fits_sip` supports arbitrary order of output axes. [#357]

API Changes

• Modified interface to wcs_from_points function to better match analogous function in astropy. [#349]
• Model._BoundingBox was renamed to ``Model.ModelBoundingBox`. [#376, #377]

Bug Fixes

• world_axis_object_components and world_axis_object_classes now ensure unique keys in CompositeFrame and CoordinateFrame. [#356]
• Fix issue where RuntimeWarning is raised when there are NaNs in coordinates in angle wrapping code [#367]
• Fix deprecation warning when wcs is initialized with a pipeline [#368]
• Use CD formalism in WCS.to_fits_sip(). [#380]
