GWCS v0.22.1

Fix inequality sign for bounding box handling [#540]

GWCS v0.22.0

• Replace usages of copy_arrays with memmap [#503]

• Fix an issue with units in wcs_from_points. [#507]

• Fix incorrect units being returned in the low level WCS API. [#512]

• Synchronize region.py with the copies of it in JWST and Romancal. [#517]

• Add support for compound bounding boxes and ignored bounding box entries. [#519]

• Add gwcs.examples module, based on the examples located in the testing conftest.py. [#521]

• Force bounding_box to always be returned as a F ordered box. [#522]

• Move the bounding box attachment to the forward transform property. [#532]

• Adjust world_to_array_index_values to round to integer coordinates as specified by APE 14. [#525]

• Add warning filter to asdf extension to prevent the bounding_box order warning for gwcs objects originating from a file. [#526]

• Fixed a bug where evaluating the inverse transform did not
  respect the bounding box. [#498]

• Improved reliability of inside/outside footprint computations when evaluating
  inverse transform with bounding box. [#536]

GWCS v 0.21.0

• Improve documentation
• Introduce a minimum version of asdf-wcs-schemas

GWCS v 0.20.0

Changes in GWCS 0.20.0

• Replace pkg_resources with importlib.metadata. [#478]
• Serialize and deserialize pixel_shape with asdf. [#480]

GWCS v 0.19.0

GWCS v 0.19.0

Bug Fixes

• Synchronize array_shape and pixel_shape attributes of WCS objects. [#439]
• Fix failures and warnings woth numpy 2.0. [#472]

Other

• Remove deprecated old bounding_box. The new implementation is released with astropy v 5.3. [#458]
• Refactor CoordinateFrame.axis_physical_types. [#459]
• StokesFrame uses now astropy.coordinates.StokesCoord. [#452]
• Dropped support for Python 3.8. [#451]
• Fixed a call to astropy.coordinates in wcstools.wcs_from_points. [#448]
• Code and docstrings clean up. [#460]
• 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]

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]
