For an E –2 spectrum, the observed 90% C.L. flux upper limits are ~10^–12 TeV^–1 cm^–2 s^–1 for energies between 1 TeV and 1 PeV in the northern sky and ~10^–11 TeV^–1 cm^–2 s^–1 for energies between 100 TeV and 100 PeV in the southern sky. This represents a 40% improvement compared to previous publications, resulting from both the additional year of data and the introduction of improved reconstructions. In addition, we present the first results from an all-sky search for extended sources of neutrinos. We update the results of searches for neutrino emission from stacked catalogs of sources and test five new catalogs; two of Galactic supernova remnants and three of active galactic nuclei.
