I will discuss recent developments on the subject of acceleration and transport of Galactic Cosmic Rays. Recent observations, and the data collected by AMS02 in particular, have revealed a number of unexpected features in the spectra of both primary and secondary cosmic rays. These findings seem to challenge the standard description of cosmic-ray propagation through the Galaxy and also impact our theories on the origin of these particles. I will discuss how at least some, if not all, of the presumed anomalies allow for an explanation based on non-linear effects associated with CR transport, and more generally what they suggest about the origin and propagation of Galactic Cosmic Rays.
