  The Fortran-versions of the CORSIKA air shower simulation code have been at
the core of simulations for many astroparticle physics experiments for the last
30 years. Having grown over decades into an ever more complex software,
maintainability of CORSIKA has become increasingly difficult, though its
performance is still excellent. In 2018, therefore a complete rewrite of
CORSIKA has begun in modern modular C++. Today, CORSIKA 8 has reached important
milestones with a full-fledged implementation of both the hadronic and
electromagnetic cascades, the ability to simulate radio and Cherenkov-light
emission from air showers and an unprecedented flexibility to configure
simulation media and their geometries.
  This presentation will discuss the current status of CORSIKA 8, highlight the
new possibilities already available, and future prospects of this new air
shower simulation framework.
