  RooFit is a toolkit for statistical modelling and fitting, and together with
RooStats it is used for measurements and statistical tests by most experiments
in particle physics. Since one year, RooFit is being modernised. In this talk,
improvements already released with ROOT will be discussed, such as faster data
loading, vectorised computations and more standard-like interfaces. These allow
for speeding up unbinned fits by several factors, and make RooFit easier to use
from both C++ and Python.
