+  for detecting and fitting 2D spectral tilt from arc lamp images. [#303]
 
 - Added new ``specreduce.tilt_solution`` module with a ``TiltSolution`` class
   that stores the fitted tilt model and provides bidirectional coordinate
-  transforms between detector and tilt-corrected frames,
-  flux-conserving 2D resampling, GWCS export via a ``gwcs`` property, and
-  reconstruction from a GWCS object via ``TiltSolution.from_gwcs()``.
