Present status of light flavoured scalar resonances

Abstract

This talk is a brief account of recent developments on light scalar meson spectroscopy. I mostly focus on the major revision of the $\sigma$ or $f_0(500)$ meson in the Review of Particle Physics, driven by new data and the accummulation of rigorous dispersive studies, but I also comment on recent updates of other scalars and future progress.
