+Improvements
+############
+
+- In Abins the instrumental broadening implementation has been overhauled.
+
+ - Output spectra from Abins should now be smooth and free of artefacts.
+ - A fast approximate scheme is implemented and automatically applied
+ when appropriate for simulations of TOSCA spectra. Alternative
+ broadening implementations may be selected through the
+ AbinsParameters system, including slow reference methods.
+ - Spectra now follow the broader Mantid convention for histograms:
+ values correspond to frequencies at the mid-points of the
+ histogram bins. (Previously the values would correspond to one
+ bin-edge.)
