==================
Backwards Incompatible Changes
------------------------------
- We now require gwcs 0.19+ and therefore astropy 5.3+ (`305 <https://github.com/DKISTDC/dkist/pull/305>`_)
Features
--------
- Add a new ``AsymmetricMapping`` model to allow a different mapping in the forward and reverse directions. (`305 <https://github.com/DKISTDC/dkist/pull/305>`_)
Bug Fixes
---------
- Fix the oversight where, when generating a model for a celestial WCS, the scale model was put before the affine transform in the pipeline. This means that the units for the affine transform matrix provided to ``VaryingCelestialTransform`` and ``generate_celestial_transform`` should be pixels not degrees. (`305 <https://github.com/DKISTDC/dkist/pull/305>`_)
- Fix missing references to parent transform schemas in ``Ravel`` and ``VaryingCelestialTransform`` ASDF schemas. (`305 <https://github.com/DKISTDC/dkist/pull/305>`_)
Trivial/Internal Changes
------------------------
- To improve compatibility with external libraries that provide ASDF serialization and
validation (like asdf-astropy) dkist schemas were updated to use tag wildcards
when checking tagged objects (instead of requiring specific tag versions). (`308 <https://github.com/DKISTDC/dkist/pull/308>`_)
