We report on the status of an update of our collaboration’s previous computation [1] of light and
strange quark masses in QCD with $N_f=2+1$ dynamical flavours. Bare quark masses are extracted
from CLS ensembles, using 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 ∼ 0.038 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.
