Updates on the Columbia plot and its extended/alternative versions

We report on the status of ongoing investigations aiming at locating the deconfinement critical point with standard Wilson fermions and \(N_f=2\) flavors towards the continuum limit (standard Columbia plot); locating the tricritical masses at imaginary chemical potential with unimproved staggered fermions at \(N_f=2\) (extended Columbia plot); identifying the order of the chiral phase transition at \(\mu=0\) for \(N_f=2\) via extrapolation from non integer \(N_f\) (alternative Columbia plot).
