I present new results and updates for total cross sections and differential distributions in topantitop pair and single-top production. Soft-gluon corrections are added to exact fixed-order results to provide the best predictions at approximate N3LO for tt¯ production and approximate NNLO for single-top production. Total cross sections and top-quark transverse-momentum and rapidity distributions are presented and compared with data at LHC and Tevatron energies. The cusp anomalous dimension at three and higher loops is also discussed.
