Here we update the global fit of neutrino oscillations in Refs.[T. Schwetz, M. Tortola, and JWF Valle, New J. Phys. 13, 063004 (2011); T. Schwetz, M. Tortola, and JWF Valle, New J. Phys. 13, 109401 (2011)] including the recent measurements of reactor antineutrino disappearance reported by the Double Chooz, Daya Bay, and RENO experiments, together with latest MINOS and T2K appearance and disappearance results, as presented at the Neutrino-2012 conference. We find that the preferred global fit value of θ 13 is quite large: sin 2 θ 13≃ 0.025 for normal and inverted neutrino mass ordering, with θ 13= 0 now excluded at more than 10 σ. The impact of the new θ 13 measurements over the other neutrino oscillation parameters is discussed as well as the role of the new long-baseline neutrino data and the atmospheric neutrino analysis in the determination of a non-maximal atmospheric angle θ 23.
