  We present an up-to-date global analysis of solar, atmospheric, reactor, and
accelerator neutrino data in the framework of three-neutrino oscillations. We
provide results on the determination of theta_13 from global data and discuss
the dependence on the choice of reactor fluxes. We study in detail the
statistical significance of a possible deviation of theta_23 from maximal
mixing, the determination of its octant, the ordering of the mass states, and
the sensitivity to the CP violating phase, and discuss the role of various
complementary data sets in those respects.
