- API Add clone() args (min, max, data, etc)
- API histogram(): add normalize_to=nn param to simplify pictures
- BUG Rewrite add_data_hash to handle -Inf properly (as in 'forget this data')
- BUG Fix stdev/variance calculation, fix pod
- TST save-load.pl: read pairs; min|max|trim|noize; - for STDIN/OUT; summary
- TST Use proper RE for numbers across examples
- TST Rewrite example/gen-sample.pl: arbitrary formulas + some std. distros

0.08 Tue May 12 2015
- API Change default base 10**1/48 (~5%) => 10**1/232 (~1%);

- that at least works for discrete distributions;
- API add_data_hash() can be used to forget data if needed;
- API Add cdf(x,y) for probability of value between x and y;
- BUG Make all methods return undef if there's no data;
- DOC Add more examples to POD: basic usage, save/load, histogram;
- DOC Add examples/save-load.pl (works with JSON files);
- DOC Cleanup examples (summary, png) in examples directory;
- DOC Add README.md for github
0.07 Mon Apr 27 2015
- DOC Rename buckets => bins in POD and comments
- API Add linear approximation approximation around zero
- ('linear_width' and 'linear_thresh' parameters in new())
- API Add TO_JSON() method which returns unblessed hash
- API Add 'data' parameter to new() to add initial data
- API Deprecate old zero handling (zero_thresh)
0.06 Wed Jul 10 2013
- TST Add png example
- API Add histogram() - better frequency_distribution_ref
- API Add scale_sample() to gradually "forget" data
- API Add find_boundaries to get (min, max) of selected sample part
