We present a new set of isochrones in which the effect of the α-element enhancement is fully incorporated. The isochrone tables, together with interpolation routines in age and chemical composition, and in [α/Fe] are available on request as well as from the electronic version of our ApJ papers. Newly derived ages of Galactic globular clusters using these isochrones are 20 to 30% smaller than previous estimates.
