A comprehensive measurement of solar neutrino fluxes has been completed using the Borexino Phase-II data in an extended energy range. The measurement reports pp, 7Be, and pep neutrino fluxes with the highest precision ever achieved, 8B with the lowest energy threshold, the first Borexino limit on hep neutrinos, as well as the best limit on CNO neutrinos. These results and their physics interpretations concerning the so-called solar metallicity puzzle and the electron-neutrino survival probability, as well as other highlights of the analysis, have been summarized in this talk.
