It is well-known that infrared singularities arise in scattering amplitudes due to the emission of soft (low energy) gluons and / or gravitons. These are important for collider predictions, but also give us all-order insights into perturbation theory. This talk will review a number of recent developments in this area, such as: the structure of IR singularities in multiparton scattering amplitudes; the relationship between Yang-Mills theory and gravity in the soft limit; the classification of amplitudes beyond the soft approximation.
