We report results from a new study of lattice QCD with decreased lattice spacing and using two flavours of light dyanamical quarks at finite temperature and chemical potential through the method of Taylor series expansions. With a factor of two in lattice spacings covered to date, the approach to the continuum limit is controlled better. In units of the inverse Compton wavelength of the light pion, the lattice volumes remain as large as before. We construct ratios of susceptibilities along the freezeout curve, thus improving upon previous results and allowing us to make more reliable predictions of the results of experiments on the shape of event-to-event fluctuations of various conserved quantities in heavy-ion collisions.
