new energy-flow algorithm, optimized for better compatibility with pile-up subtraction added possibility of computing pile-up density in different eta regions via the RhoEtaRange parameter in FastJetFinder module implemented correct efficiency/resolution for high pt muons in CMS cards removed pile-up subtraction on missing energy added possibility to read re-weighting information from LHEF input files added UsePTSum and PTSumMax parameters to isolation module added possibility of specifying the shape of pile-up distribution (via the PileUpDistribution parameter in the PileUpMerger module) added pile-up Vertex collection to the output tree
