  Monte Carlo methods cannot probe far into the QCD phase diagram with a real
chemical potential, due to the famous sign problem. Complex Langevin
simulations, using adaptive step-size scaling and gauge cooling, are suited for
sampling path integrals with complex weights. We report here on tests of the
deconfinement transition in pure Yang-Mills SU(3) simulations and present an
update on the QCD phase diagram in the limit of heavy and dense quarks.
