We present new νμ→νe, νμ→νμ, ¯νμ→¯νe, and ¯νμ→¯νμ 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 νe, vμ, ¯νe, and ¯νμ 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 θ23 mixing angle, with Δm232=(2.41±0.07)×103eV2 and sin2θ230.57+0.03−0.04. The data disfavor combinations of oscillation parameters that give rise to a large asymmetry in the rates of νe and ¯νe appearance. This includes values of the charge parity symmetry (CP) violating phase in the vicinity of δCP=π/2 which are excluded by 

>3σ for the inverted mass ordering, and values around δCP=3π/2 in the normal ordering which are disfavored at 

2σ confidence.
