Since the beginning of LHC Run 2, many improvements have been made to the tau lepton reconstruction algorithm at CMS. The hadrons-plus-strips (HPS) tau leptons reconstruction algorithm now benefits from a dynamic strip reconstruction, and has been extended to a version intended for highly Lorentz-boosted topologies. In addition, multivariate discriminators used for tau lepton identification now combine isolation with lifetime variables. The methodology and performance of the newly developed
