+Version 1.5.0
+=============
+*2024 December*
+WebbPSF IS BEING MIGRATED TO A NEW REPOSITORY: STPSF (Space Telescope PSF)
+To reflect its broader support for Roman as well as James Webb, WebbPSF is being migrated to a new repository: STPSF (Space Telescope PSF).
+This transition is being done in such a way as to maintain back-compatibility for existing code, and existing installations will continue to run as-is.
+This release will be among the final releases to WebbPSF and the initial release to STPSF.
+
+This release requires new data webbpsf-data-1.5.0 https://stsci.box.com/s/oyoih9ibuaowksxzaia02ua4t6g1bbp1
+For more information on this new data please view https://github.com/spacetelescope/webbpsf/pull/937
