    FilteredClassifier now extends SingleClassifierEnhancer. Note that this means that the double hyphen construct now needs to be used to specify the classifier options. Another change: Discretize is now the default filter.

    Decorate now extends RandomizableIteratedSingleClassifierEnhancer for simplified option handling. Unfortunately, the letters for the command line options had to be changed. What used to be I is now E, and what used to be M is now I. Also, the maximum and desired number of iterations are now both set to 10 by default (instead of 50 and 15 respectively).
