The computational framework MATRIX is introduced, which has recently been published. The code allows for the evaluation of fully differential NNLO predictions for a wide class of processes in hadronic collisions, including the production of a single or a pair of color-neutral bosons. By accounting for all resonant and non-resonant diagrams, off-shell effects and spin correlations, all possible leptonic channels have become available for the first time. I review relevant phenomenological results for diboson production obtained with MATRIX and present novel NNLO results for two lepton plus missing ET signatures. Furthermore, the development of transverse-momentum resummation at NNLL for all processes available within the MATRIX framework is discussed.
