Using new four-loop results for the heavy quark vacuum polarization and new data for bottom quark production in electron-positron annihilation, an update on the determination of charm-and bottom-quark masses through sum rules has been performed. The previous result for the charm-quark mass, m(c)(3 GeV) = 0.986(13) GeV, based on the lowest moment, is supported by the new results from higher moments which lead to consistent values with comparable errors. The new value for the bottom quark, mb(10 GeV) = 3.610(16) GeV, corresponding to m(b)(m(b)) = 4.163(16) GeV, makes use of both the new data and the new perturbative results and is consistent with the earlier determination.
