- Update to version 3.4.3:
  + Makefile.*
    Add missing copyright/licenses
  + liblinear, libsvm:
    add license from original author
  + roc.m: number of data points limited to about 5000
    add final data point at (1,1).
- Update to version 3.4.0:
  + quadratic classifiers:
    check for positive-definiteness of covariance matrix
    and return no classification (encoded as NaN), if not.
  + mad, meandev:
    make sure source is ascii/utf-8 compliant
- Update to version 3.3.0:
  + detrend: the 2nd output (trend) can be interpolated and should
    not contain NaNs.
  + train_sc: some supported classifiers should not be used
    with the short-cut for two-class problems.
  + xval: report also results w/o crossvaliation
  + ecdf: fix ylim in case data contains missing values.
- Update to version 3.2.3:
  + <NEW> ROC is included. ROC is derived
    from the implementation in "biosig for octave and matlab"
    	biosig-code/biosig4matlab/t490_EvaluationCriteria/

    sample sizes smaller than N=25
  + corrcoef: improve documentation on one-
    and two- pass algorithm
  + histogram functions (histo.m) included
  + upgrade to liblinear 2.2.1
    weightening of samples not supported anymore
