0.21.0 (2024-03-10) ------------------- - Improve documentation. [#483] - Add a minimum version requirement for ``asdf-wcs-schemas``. [#491] - Fix ``WCS.__str__`` for instances without transforms. [#489] 0.20.0 (2023-11-29) ------------------- - Replace ``pkg_resources`` with ``importlib.metadata``. [#478] - Serialize and deserialize ``pixel_shape`` with asdf. [#480] 0.19.0 (2023-09-15) ------------------- Bug Fixes ^^^^^^^^^ - Synchronize ``array_shape`` and ``pixel_shape`` attributes of WCS objects. [#439] - Fix failures and warnings with 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] 0.18.3 (2022-12-23) ------------------- Bug Fixes ^^^^^^^^^ - Fixed a bug in the estimate of pixel scale in the iterative inverse code. [#423] - Fixed constant term in the polynomial used for SIP fitting. Improved stability and accuracy of the SIP fitting code. [#427] 0.18.2 (2022-09-07) ------------------- Bug Fixes ^^^^^^^^^ - 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] New Features ^^^^^^^^^^^^ 0.18.1 (2022-03-15) ------------------- Bug Fixes ^^^^^^^^^ - Remove references to the ``six`` package. [#402] 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] - Added support to ``_compute_lon_pole()`` for computation of ``lonpole`` for all projections from ``astropy.modeling.projections``. This also extends support for different projections in ``wcs_from_fiducial()``. [#389] 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] 0.17.1 (2021-11-27) ------------------- Bug Fixes ^^^^^^^^^ - Fixed a bug with StokesProfile and array types. [#384] 0.17.0 (2021-11-17) ------------------- 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] 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] 0.16.1 (2020-12-20) ------------------- Bug Fixes ^^^^^^^^^ - Fix a regression with ``pixel_to_world`` for output frames with one axis. [#342] 0.16.0 (2020-12-18) ------------------- New Features ^^^^^^^^^^^^ - Added an option to `to_fits_sip()` to be able to specify the reference point (``crpix``) of the FITS WCS. [#337] - Added support for providing custom range of degrees in ``to_fits_sip``. [#339] Bug Fixes ^^^^^^^^^ - ``bounding_box`` now works with tuple of ``Quantities``. [#331] - Fix a formula for estimating ``crpix`` in ``to_fits_sip()`` so that ``crpix`` is near the center of the bounding box. [#337] - Allow sub-pixel sampling of the WCS model when computing SIP approximation in ``to_fits_sip()``. [#338] - Fixed a bug in ``to_fits_sip`` due to which ``inv_degree`` was ignored. [#339]
