The results of the three separate phases were already published, as well as the results of a combined analysis of the first two phases. The combination of the full 3-phase data set was recently finalized and submitted for publication. The new results were shown in this communication. The neutron signal identification and calibration in the third phase data was improved, as well the signal extraction and 3-flavor neutrino oscillation analyses. By making full use of the knowledge of correlated systematic uncertainties between phases, the combined 3-phase analysis provided the most accurate solar neutrino flux measurements from SNO, and the most precise constraints on the neutrino oscillation parameters.
