  GENIE is a neutrino Monte Carlo event generator that simulates the primary
interaction of a neutrino with a nuclear target, along with the subsequent
propagation of the reaction products through the nuclear medium. It
additionally contains libraries for fully-featured detector geometries and for
managing various types of neutrino flux. This note details recent updates to
GENIE, in particular changes introduced into the newest production release,
version 2.10.0.
