The article presents a selected set of recent results from numerical investigations of QCD at finite temperature. It is focused  (i) on the present understanding of thermodynamic properties of QCD in the presence of dynamical quarks at various masses and at small yet phenomenologically relevant values for the baryon density and  (ii) on a fairly new approach to studying thermal hadronic excitations.
