    What's new in 3.7.10?

    Some highlights
    ---------------

    In core weka:

    * HoeffdingTree. Ported from the MOA implementation to a Weka classifier
    * MergeInfrequentNominalValues filter
    * MergeNominalValues filter. Uses an CHAID-style merging routine
    * Zoom facility in the Knowledge Flow
    * Epsilon-insensitive and Huber loss functions in SGD
    * More CSVLoader improvements
    * Class specific IR metric based evaluation in WrapperSubsetEval
    * GainRatioAttributeEval now supports instance weights
    * New command line option to force batch training mode when the classifier is an incremental one
    * LinearRegression is now faster and more memory efficient thanks to a contribution from Sean Daugherty
    * CfsSubsetEval can now use multiple CPUs/cores to pre-compute the correlation matrix (speeds up backward searches)
    * GreedyStepwise can now evaluate mutliple subsets in parallel

    In packages:

    * New kernelLogisticRegression package
    * New supervisedAttributeScaling package
    * New clojureClassifier package
    * localOutlierFactor now includes a wrapper classifier that uses the LOF filter
    * scatterPlot3D now includes new Java3D libraries for all major platforms
    * New IWSS (Incremental Wrapper Subset Selection) package contributed by Pablo Bermejo
    * New MODLEM package (rough set theory based rule induction) contributed by Szymon Wojciechowski

    As usual, for a complete list of changes refer to the changelogs.

    Cheers,
