Developments in perturbative QCD

14 pages; invited talk at XXII International Symposium on Lepton-Photon Interactions at High Energy, Uppsala, July 2005; v2 includes extra referencesA brief review of key recent developments and ongoing projects in perturbative QCD theory, with emphasis on conceptual advances that have the potential for impact on LHC studies. Topics covered include: twistors and new recursive calculational techniques; automation of one-loop predictions; developments concerning NNLO calculations; the status of Monte Carlo event generators and progress in matching to fixed order; analytical resummation including the push to NNLL, automation and gap between jets processes; and progress in the understanding of saturation at small x
