 Summary of important user-visible changes for statistics 1.6.0:
-------------------------------------------------------------------

 Important Notice: 1) dependency changed to Octave>=7.2.0
                   2) various distribution functions have been
                       renamed, deprecated, or modified extensively
                       so that backwards compatibility is broken
                   3) `mad`, `mean`, `median`, `std`, `var` functions
                       shadow core Octave's respective functions
