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 algorithms and discriminators are presented using 35.9 $\textrm{fb}^{-1}$ and 41.4 $\textrm{fb}^{-1}$ of proton-proton data collected with CMS in the 2016 and 2017 LHC runs.
