-------------------

-------------------

- Improve documentation. [483]

- Add a minimum version requirement for ``asdf-wcs-schemas``. [491]

- Fix ``WCS.__str__`` for instances without transforms. [489]

-------------------

- Replace ``pkg_resources`` with ``importlib.metadata``. [478]

- Serialize and deserialize ``pixel_shape`` with asdf. [480]

-------------------

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]

-------------------
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]

-------------------
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]
