  Status of tau lepton decay Monte Carlo generator TAUOLA is reviewed. Recent
efforts on development of new hadronic currents are presented. Multitude new
channels for anomalous tau decay modes and parametrization based on defaults
used by BaBar collaboration are introduced. Also parametrization based on
theoretical considerations are presented as an alternative.
  Lesson from comparison and fits to the BaBar and Belle data is recalled. It
was found that as in the past, in particular at a time of comparisons with CLEO
and ALEPH data, proper fitting, to as detailed as possible representation of
the experimental data, is essential for appropriate developments of models of
tau decays.
  In the later part of the presentation, use of the TAUOLA program for
phenomenology of W,Z,H decays at LHC is adressed. Some new results, relevant
for QED bremsstrahlung in such decays are presented as well.
