Abstract: We report on the status of a long term project to determine the nature of the thermal transition in QCD (the fundamental theory of strongly interacting matter composed of quarks and gluons) as a function of the number of quark flavours, their masses, imaginary chemical potential for baryon number and the lattice spacing. Our knowledge on the order of the thermal QCD transition depending on these parameters is summarised in what is known as Columbia plot. Besides showing the structure of the theory, it is important to constrain the QCD phase diagram realised by nature, which cannot be simulated directly due to a severe sign problem at real baryon chemical potentials. Having determined the qualitative structure of the Colombia plot in earlier studies, current efforts focus on reducing the lattice spacing and understanding discretisation effects, which need to be removed to arrive at continuum results.
