Query: High precision determination of $\alpha_s$ from a global fit of jet
  rates   We present state-of-the-art extractions of the strong coupling based on
N$^3$LO+NNLL accurate predictions for the two-jet rate in the Durham clustering
algorithm at $e^+e^-$ collisions, as well as a simultaneous fit of the two- and
three-jet rates taking into account correlations between the two observables.
The fits are performed on a large range of data sets collected at LEP and PETRA
colliders, with energies spanning from $35$ GeV to $207$ GeV. Owing to the high
accuracy of the predictions used, the perturbative uncertainty is considerably
smaller than that due to hadronization. Our best determination at the $Z$ mass
is $\alpha_s(M_Z) = 0.11881 \pm 0.00063(exp.) \pm 0.00101(hadr.) \pm
0.00045(ren.) \pm 0.00034(res.)$, which is in agreement with the latest world
average and has a comparable total uncertainty.
