Stdatamodels

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

- Added ALL_MRS to allowed values for keyword MRSPRCHN in core
schema. [285]

- Provide existing ``AsdfFile`` instance to ``validate`` to
speed up assignment validation ``check_value``. [276]

- Deprecate ``deprecate_class`` unused by downstream. [274]

- Add cache to hdu accesses during ``_load_from_schema``
to speed up file opening. [278]

- Remove ``TEXPTIME`` keyword from the JWST core datamodel schema
because it duplicates the information of ``XPOSURE``. [277]

- Deprecate ``check_memory_allocation``. This function did not
work as intended. [273]

- Decrease size of ``SPECTYP`` and ``TARGET`` columns in
``OI_TARGET`` table of oifits schema to 16 characters. [281]

- Change ``integration_number`` from int16 to int32 in ``group``
schema. [283]

- Fix datamodel schema ids for abvegaoffset, keyword_lampmode, nrsfs_apcorr [258]

- Drop support for python 3.9 [287]

- Convert ``FITS_rec`` instances read from old files where a
hdu was linked in the old schema (but is no longer linked)
when rewriting files. [268]

- Deprecate ``skip_fits_update`` and environment variable
``SKIP_FITS_UPDATE``. Future behavior will be as if
``skip_fits_update`` was ``False`` and the FITS headers
will always be read [270]

- Increase minimum required asdf version [288]

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

Bug Fixes
---------

- Adding "IMAGER" as another allowed value for the "MRSPRCHN"
keyword, in order to support proper handling of MIRI MRS
and Imager exposures done in parallel. [259]

- Fix mask schema to allow for non-integer ngroups selectors [256]

Changes to API
--------------

- Add ``NRMModel`` for new NIRISS NRM reference file [253]

Other
-----

- Add ``grating`` keyword to JWST ``barshadow`` ref file schema to match
parkeys on crds [260]

- Add ``average_dark_current`` in both scalar keyword and array extension
options to ``DarkModel`` and ``MIRIDarkModel``. Add the array extension
to the ``RampModel``, for tracking the average dark current. [265]

- Add ``EXTRXSTR``, ``EXTRXSTP``, ``EXTRYSTR``, and ``EXTRYSTP`` keywords
to the jwst ``MultiSpec`` schema. [264]

Changes to API
--------------

- Remove ``json_id`` argument use for callbacks passed
to ``asdf.treeutil.walk_and_modify`` [244]

Other
-----

- Add ``ngroups`` keyword to JWST ``mask`` ref file schema to match
parkeys on crds [249]

- Added keywords ``noutputs`` and ``bunit`` to the JWST
readnoise and superbias datamodel schemas. [250]

- Updated JWST core datamodel schema to include the new
``TMEASURE`` keyword for measurement time. [248]

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

Bug Fixes
---------

- Fix search in documentation [241]

Changes to API
--------------

- Deprecate ``cast_arrays`` argument to ``from_fits_hdu`` and
``cast_fits_arrays`` argument to ``Datamodel.__init__`` [214]

- Use ``DataModel.__init__`` ``memmap`` argument when opening ASDF
files [232]

Other
-----

- Updated JWST core datamodel schema to include the new step status keyword
"S_NSCLEN" for the new "nsclean" calibration step. [237]

- Adding emicorr datamodel and schema, as well as
corresponding completion and reference file keywords [200]

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

Bug Fixes
---------

- Fixed ``ValidationError`` during ``AmiOIModel.update`` [234]

- Fix ``rebuild_fits_rec_dtype`` handling of unsigned integer columns
with shapes [213]

- Fix unit roundtripping when writing to a datamodel with a table
to a FITS file [242]

Changes to API
--------------

- Sort keyword files used for schema_editor to make output non-arbitrary
copy schema before merging to avoid schema modification [227]

Other
-----

- Add mrsptcorr ref_file to core.schema [228]

- Avoid unnecessary validation during ``DataModel.clone`` [230]

- Replace uses of ``utcnow`` (deprecated in python 3.12) [231]

- Updated JWST MIRI imager photom model to include time-dependent correction
coeffs. [235]

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

Other
-----

- Add ``channel`` keyword to MIRI MRS Apcorr schema [224]
