Description
We report on the status of an update of our previous computation of light and strange quark masses in QCD with $N_f=2+1$ dynamical flavour. Bare quark masses are extracted from CLS ensembles, using $\mbox{O}(a)$-improved Wilson fermions, and the mass renormalization is performed non-perturbatively in the Schrödinger functional scheme over a wide range of scales to make safe contact with perturbation theory. Results for five lattice spacings, down to $a \approx 0.038 \,\mathrm{fm}$, and pion masses reaching the physical value are included in the analysis. This allows for the exploration of different models for cutoff and chiral effects, and a controlled extrapolation to the physical point.
