Recent developments in thermal leptogenesis are reviewed. Neutrino mixing data support a simple picture where the asymmetry is generated by the decays of the heavy Majorana neutrinos mildly close to thermal equilibrium and, remarkably, in the full non relativistic regime. Neutrino masses larger than 0.1 eV are not compatible with the minimal scenario. We also discuss how this result is stable turning to the supersymmetric scenario or under addition of decoupled species or considering degenerate heavy neutrino mass spectrum.
