  During the last 15 years the Radio MonteCarLow Working Group has been
providing valuable support to the development of radiative corrections and
Monte Carlo event generators for low energy $e^+e^-$ data and $\tau$-lepton
decays. While the working group has been operating for more than 15 years
without a formal basis for funding, parts of our program have recently been
included as a Joint Research Initiative in the group application of the
European hadron physics community, STRONG2020, to the European Union, with a
more specific goal of creating an annotated database for low-energy hadronic
cross sections in $e^+e^-$ collisions. In parallel the theory community is
continuing its effort towards the realization of improved Monte Carlo
generators with for low energy $e^+e^-$ data into hadrons. Full NNLO
corrections in the leptonic sector are to be combined with an improved
treatment of radiative corrections involving pions. This is of relevance for
the precise determination of the leading hadronic contribution to the muon g-2.
We will report on these initiatives.
