Version 0.9.1
This minor release resolves several bugs and occasional installation issues and updates behind-the-scenes package infrastructure for consistency with current astropy and numpy releases. There are small improvements to a few aspects of JWST models as detailed below (in particular for wavelength dispersion in NIRCam LW coronagraphy and in tools for modeling time-dependent WFE) but the vast majority of JWST PSF calculations are not changed in any way.
