Comment on ``Next-to-next-to-leading order vacuum polarization function of heavy quark near threshold and sum rules for b bar b system'' and ``Next-to-next-to-leading order relation between R(e^+e^-to bbar b) and Gamma_(rm sl)(bto clν_l) and precise determination of |V_(cb)|''

The most recent recalculation of the two-loop correction to the static quark-antiquark potential gave the numerical value different from the previously known one. We comment on the effect this change produces on the numerical estimates of the bottom quark pole mass $m_b$, the strong coupling constant $\al_s$ and the Cabibbo-Kobayashi-Maskawa matrix element $|V_{cb}|$ obtained in our papers [1,2].
