===================

- Allow assignment to or creation of node attributes using dot notation of object instances
with validation. [284]

- Add ``meta.wcs`` to ``maker_utils``. [302]

- Remove duplicate validation during ``DataModel.to_asdf``, replace assumed validation
during ``AsdfFile.__init__`` with call to ``AsdfFile.validate`` [301]

===================

- Allow DNode and LNode subclass instances to be assigned to tree attributes and support
validation of all such instances. [275]

- Update minimum version of astropy to 5.3.0 in order to fix a bug due to a breaking
change in astropy. [258]

- Update minimum version of numpy to 1.22 as this is the oldest version of numpy
which is currently supported. [258]

- Fix the initialization of empty DataModels and clean up the datamodel core. [251]

- Add slope and error to dark RefModel and tests. [280]

- Added truncation to exposure. [283]

- Added optional dq array to science raw maker utility and test. [282]

- Updated the WFI_Mosaic datamodel, maker utilities, and tests to a more streamlined metadata design for level 3 products. [288]

===================

- Fix newly required units from rand [256]

===================

- Add checks for for association processing [241]

- Make a shallow copy when opening an existing datamodel, rather than
a full copy. [232]

- Remove the ``random_utils`` module and make ``maker_utils`` entirely deterministic. [217]

- Add tests to ensure consistency between file-level schemas in RAD and the corresponding
datamodels in ``roman_datamodels``. [214]

- Make ``maker_utils`` return the node when writing the node to a file. [218]

- Clean up overlooked randomness in ``maker_utils`` and tests. [236]

- Remove the unused ``target`` keyword from ``rdm_open`` and fix the original issue that the
keyword was meant to address; namely, passing a datamodel instance to the constructor for
that datamodel instance should return the instance back with no modifications. [235]

- Use ValidationError from asdf.exceptions instead of jsonschema. Increase minimum
asdf version to 2.15.0. [234]

- Update ``maker_utils`` to support the new ``cal_step`` keys. [228, 243]

- Clean up the ``rdm_open`` function. [233]

- Include tests in coverage and turn testing warnings into errors. [238]

- Add ``__repr__`` to ``DNode``. [245]
