  The Daya Bay reactor neutrino experiment observed electron antineutrino
disappearance associated with $\theta_{13}$ with a significance better than
$5\sigma$ in 2012. The final two of eight antineutrino detectors were installed
in the summer of 2012. Including the 404 days of data collected with the full
detector configuration resulted in a 3.6 times increase of statistics over the
previous result with the 6-AD configuration. With improvements of the
systematic uncertainties and better estimation of backgrounds, Daya Bay has
measured $\sin^22\theta_{13} = 0.084\pm0.005$ and $|\Delta
m^2_{ee}|=2.42^{+0.10}_{-0.11}\times 10^{-3}$~eV$^2$. This is the most precise
measurement of $\sin^22\theta_{13}$ to date and the most precise measurement of
of $|\Delta m^2_{ee}|$ via electron antineutrino disappearance. Several other
analysis results are presented, including an independent measurement of
$\theta_{13}$ using inverse-beta decays associated with neutron capture on
hydrogen, a measurement of reactor antineutrino flux and spectrum, and a search
for light sterile neutrino mixing.
