The Neil Gehrels <i>Swift</i> Observatory was launched in Nov. 20, 2004. The Burst Alert Telescope (BAT) onboard <i>Swift</i> has detected more than 1200 Gamma-ray Bursts (GRBs), of which about 1/3 of GRBs have redshift measurements, ranging from z = 0.01 to z = 9.38. We present the analyses of the BAT-detected GRBs for the past ~11 years up through GRB 151027B in <A HREF="https://arxiv.org/abs/1606.01956">the third Swift/BAT GRB catalog</A>. The result summaries and data products are available at the public website: <A HREF="http://swift.gsfc.nasa.gov/results/batgrbcat/">The Swift/BAT GRB Catalog</A>, which is continued to be updated with recent bursts.
