  We outline a new technique for the fully-differential matching of final-state
parton showers to NNLO calculations, focussing here on the simplest case of
leptonic collisions with two final-state jets. The strategy is facilitated by
working in the antenna formalism, making use of NNLO antenna subtraction on the
fixed-order side and the sector-antenna framework on the shower side. As long
as the combined real-virtual and double-real corrections do not overcompensate
the real-emission term in the three-jet region, negative weights can be
eliminated from the matching scheme. We describe the implementation of all
necessary components in the VINCIA antenna shower in PYTHIA 8.3.
