  We present an implementation of the vector boson pair production processes
ZZ, W+W- and WZ within the POWHEG BOX V2. This implementation, derived from the
POWHEG BOX version, has several improvements over the old one, among which the
inclusion of all decay modes of the vector bosons, the possibility to generate
different decay modes in the same run, speed optimization and phase space
improvements in the handling of interference and singly resonant contributions.
