Abstract
We review the status of the determination of |V_{us}| from both flavor-breaking finite-energy sum rules based on inclusive non-strange and strange hadronic tau decay data and the recent lattice-based analysis of inclusive strange hadronic tau decay data. In particular, we update the results from these analysis frameworks taking into account recent improvements to a number of strange branching fractions reported by HFLAV at CKM2018 and this meeting. We find that inclusive tau decay data yields results for |V_{us}| compatible within errors with the expectations of three-family unitarity.

Report
The conference contribution under consideration presents slightly updated results already contained in two reviewed journal publications: Phys. Lett. B781 (2018) 206 as well as Phys. Rev. Lett. 121 (2018) 202003. It is reasonably well written and clear. Hence, in my opinion there is no need for a more detailed report.
