  [BUG FIXES]

  - Changed how CPAN::Reporter::PrereqCheck attempts to load modules to

  [OTHER]

  - Bumped IPC::Cmd prereq to 0.76 to avoid failures on some platforms

        - Thanks to Salvatore Bonaccorso and the Debian Perl Group

3.0601      May 11, 2012

        - It was used by the tests and not specified in

        - Add the following public methods: add_data_with_samples(),
        set_smoother(), get_smoothed_data() to the main module.
        - Add the lib/Statistics/Descriptive/Smoother.pm and
        lib/Statistics/Descriptive/Smoother/Exponential.pm

3.0400      March 01, 2012
    - Fix https://rt.cpan.org/Ticket/Display.html?id=74890
        - some function should return undef() in list context so they can
        be easily assigned to values in hash initialisations.
        - thanks to SLAFFAN for a preliminary patch which was modified
        by SHLOMIF (the current Statistics-Descriptive maintainer).

3.0300      February 11, 2012
    - Now mean() and median() and other routines return undef() if there are
    no data.
    - Somewhat incompatible change: some methods that returned undef() under
    list context now return an empty list (so it will be false).
        - it is generally not recommended to call such methods in list context
        as they should always be called in scalar context.
    - Resolves https://rt.cpan.org/Ticket/Display.html?id=74693
        - thanks to Shawn Laffan for the report and the patch.

3.0203      November 17, 2011
    - Fix https://rt.cpan.org/Ticket/Display.html?id=72495 .
        - percentile should not die and should return undef if there are
        no elements in the collection.
Updated math/p5-Statistics-Descriptive to 3.0604
Add one more patch from Jan Beich,
mainly fix DragonFly build.
Does not build on python25; it tries to print a message saying it needs a
newer Python version, but croaks while doing so.
