We present new ?µ??e, ?µ??µ, ?¯µ??¯e, and ?¯µ??¯µ oscillation measurements by the NOvA experiment, with a 50% increase in neutrino-mode beam exposure over the previously reported results. The additional data, combined with previously published neutrino and antineutrino data, are all analyzed using improved techniques and simulations. A joint fit to the ?e, ?µ, ?¯e, and ?¯µ candidate samples within the 3-flavor neutrino oscillation framework continues to yield a best-fit point in the normal mass ordering and the upper octant of the ?23 mixing angle, with ?m322=(2.41±0.07)×10-3 eV2 and sin2?23=0.57-0.04+0.03. The data disfavor combinations of oscillation parameters that give rise to a large asymmetry in the rates of ?e and ?¯e appearance. This includes values of the charge parity symmetry (CP) violating phase in the vicinity of dCP=p/2 which are excluded by >3s for the inverted mass ordering, and values around dCP=3p/2 in the normal ordering which are disfavored at 2s confidence.
