  Status of tau lepton decay Monte Carlo generator TAUOLA, and its main recent
applications are reviewed. It is underlined, that in recent efforts on
development of new hadronic currents, the multi-dimensional nature of
distributions of the experimental data must be taken with a great care. Studies
for H to tau tau; tau to hadrons indeed demonstrate that multi-dimensional
nature of distributions is important and available for evaluation of
observables where tau leptons are used to constrain experimental data. For that
part of the presentation, use of the TAUOLA program for phenomenology of H and
Z decays at LHC is discussed, in particular in the context of the Higgs boson
parity measurements with the use of Machine Learning techniques. Some
additions, relevant for QED lepton pair emission and electroweak corrections
are mentioned as well.
