CUDPP release 2.3 is a feature release that adds the new cudppMultiSplit parallel primitive. This function takes as input an array of elements (unsigned ints) and outputs an array where the elements have been split into ordered buckets. A second version of this function, cudppMutliSplitCustomBucketMapper, allows the user to specify a custom function that assigns an element to a bucket.
A full list of changes can be viewed in the change log. The release czar for CUDPP 2.3 was Jason Mak.
