[dependabot]

Bumps jwst from 1.18.1 to 2.0.1.

Changelog

Sourced from jwst's changelog.

2.0.1 (2026-05-06)

assign_wcs (image2, spec2)

• Fix a bug where attempting to generate transforms for stripes present in the specwcs file but not the regions file caused crashes for NIRCam DHS stripe1 and stripe2 subarray data. ([#10453](https://github.com/spacetelescope/jwst/issues/10453) <https://github.com/spacetelescope/jwst/issues/10453>_)

picture_frame (detector1)

• Fix array broadcasting error for input ramp exposures with more than one integration. ([#10470](https://github.com/spacetelescope/jwst/issues/10470) <https://github.com/spacetelescope/jwst/issues/10470>_)

2.0.0 (2026-04-13)

Breaking Changes

• Make wfss_contam expect the direct image to have a WCS object instead of the segmentation map ([#9935](https://github.com/spacetelescope/jwst/issues/9935) <https://github.com/spacetelescope/jwst/issues/9935>_)
• Drop support for datamodels without int_times table ([#10042](https://github.com/spacetelescope/jwst/issues/10042) <https://github.com/spacetelescope/jwst/issues/10042>_)
• Remove deprecated AmiAverageStep (deprecated since 1.18.1) ([#10057](https://github.com/spacetelescope/jwst/issues/10057) <https://github.com/spacetelescope/jwst/issues/10057>_)
• Fix a bug where accessing array-like attributes that did not exist would set them to default values. For example, creating ImageModel((10,10)) and then accessing model.err no longer sets model.err to its default (in this case, a 10x10 array of zeros). model.get_default() must now be used instead. Setting the value must be done explicitly, e.g. model.err = model.get_default("err"). ([#10267](https://github.com/spacetelescope/jwst/issues/10267) <https://github.com/spacetelescope/jwst/issues/10267>_)
• Fix a bug where accessing metadata attributes that did not exist would set them to their schema-defined default, if one was defined. For example, creating an empty SlitModel() and then accessing model.source_id no longer sets model.source_id to its default of 0. Instead, it remains empty until specifically set. Use ``model.source_id =
