The Zwicky Transient Facility (ZTF) Bright Transient Survey aims to spectroscopically classify every extragalactic transient brighter than 18.5 mag that occurs within ZTF's 14000 square degree active footprint. After three years we have catalogued over 4500 spectroscopically confirmed SNe and a variety of other transients spanning more than six orders of magnitude in luminosity and two orders of magnitude in duration. We present the latest results from this effort, including: (1) a complete exploration of transient duration-luminosity parameter space; (2) new measurements of the SN Ia rate, core-collapse rate, and superluminous SN rate; (3) constraining limits on the influence of host-galaxy properties on the SN II to SN Ibc ratio; (4) new insight into the spectroscopic diversity of fast-evolving transients; (5) a new population of rare, very luminous nuclear transients of unknown origin. All classifications and substantial value-added information (including light curves, timescale and luminosity measurements, and host galaxies) are released in real time on the Transient Name Server and on our open project webpage.
