New Results on Tau Lepton

This is a review of new results on the Tau lepton. The lifetime has been measured with improved precision, allowing the test of lepton universality to 0.2% level. There are several new measurements of the branching ratios for the hadronic decays, including much improved measurements for the Cabibbo-suppressed decays. All results are consistent with the Standard Model expectations.
