The study of gluon radiation in QCD, in the limit of small ("soft") momentum, remains an active research area, with a variety of phenomenological and theoretical applications. Soft gluon emission leads to large logarithms in perturbation theory which have to be summed up to all orders in the coupling, and also governs the structure of infrared singularities. Recently, new techniques and mathematical structures have been discovered, which enhance our understanding of these all-order properties. This talk will review a number of key topics, including: (i) the structure of infrared divergences in multiparton scattering; (ii) constraints from the high energy limit; (iii) intriguing relations between the soft limits of QCD and quantum gravity.
