CHANGES

@@ -3,6 +3,10 @@ Next release
 * ENH: New interfaces: nipy.Trim
 
 * ENH: Allow control over terminal output for commandline interfaces
+* ENH: New workflows for dMRI and fMRI pre-processing: added motion artifact correction
+       with rotation of the B-matrix, and susceptibility correction for EPI imaging using
+       fieldmaps. Updated eddy_correct pipeline to support both dMRI and fMRI, and new parameters.
+* ENH: Minor improvements to FSL's FUGUE and FLIRT interfaces
