-## New features:
-
-  1. Add Benini distribution  `Ostap::Math::Benini`, `Ostap::Models::Benini`, `Benini_pdf`
-  1. Add cubic and 4th order terms to (modified) Benini distribution 
-  1, add the methods `min` & `max` to histogram objects 
-  1. make use for `ROOT::TDirectory::TContext` for `ROOTCWD`
-  1. imporve functions/pdf for Benini distribution allowing terms upto power 10
-  1. use 'RoMinimizer' instead of `RooMinuit` for fresh version of ROOT 
-  1. Improve treatment of `silent` for `PDF.chi2FitTo`
-  1. Add `Ostap::Math::Rational`           : simple rational function inspired by `Ostap::Math::FloaterHormann` interpolant
-  1. Add `Ostap::Math::RationalBernstein`  : rational function as ratio of Bernstein and positve Bernstein polynomials 
-  1. Add `Ostap::Math::RationalPositive`   : rational function as ratio of two positve Bernstein polynomials
-  1. Add `Ostap::Models::Rational`         : rational PDF  as ratio of two positve Bernstein polynomials
-  1. Add `Rational_pdf`                    : rational PDF  as ratio of two positve Bernstein polynomials
-  1. Add 1D-histogram parameterisations in terms      of rational functions: `rational_fun`, `rational` and `brational`
-  1. Add 1D-histogram parameterisations in terms of rational functions: `pdf_rational`
-  1. Improve a bit `tag` for 1D-Bernstein polynomials`
