We give a status report on the automation of next-to-leading order processeswithin the Monte Carlo event generator WHIZARD, using GoSam and OpenLoops asprovider for one-loop matrix elements. To deal with divergences, WHIZARD usesautomated FKS subtraction, and the phase space for singular regions isgenerated automatically. NLO examples for both scattering and decay processeswith a focus on e+e- processes are shown. Also, first NLO-studies ofobservables for collisions of polarized leptons beams, e.g. at the ILC, will bepresented. Furthermore, the automatic matching of the fixed-order NLOamplitudes with emissions from the parton shower within the POWHEG formalisminside WHIZARD will be discussed. We also present results for top pairs atthreshold in lepton collisions, including matching between a resummed thresholdcalculation and fixed-order NLO. This allows the investigation of moreexclusive differential observables.
