The neutrino mixing angle �13 is at the focus of current neutrino research. From a global analysis of the available oscillation data in a 3� framework, we previously reported [Phys. Rev. Lett. 101, 141801 (2008)] hints in favor of �13 > 0 at the 90% C.L. Such hints are consistent with the recent indications of �µ ! �e appearance in the T2K and MINOS long-baseline accelerator experiments. Our global analysis of all the available data currently provides > 3� evidence for nonzero �13, with 1� ranges sin 2 �13 = 0.021 ± 0.007 or 0.025 ± 0.007, depending on reactor neutrino flux systematics. Updated ranges are also reported for the other 3� oscillation parameters (�m 2 , sin 2 �12) and (�m 2 , sin 2 �23).
