Abstract: The present status of Chiral Perturbation Theory in the meson sector is discussed concentrating on recent developments.This write-up contains short discussions on a listing of a few historical papers, the principles behind ChPT, two-flavour ChPT including some comments about the pion polarizability, three-flavour ChPT with a discussion of the recently found relations as tests of ChPT and preliminary results of a new fit of the NLO low-energy-constants (LECs).It discusses somewhat deeper η → 3π and the arguments for the existence of a "hard pion ChPT" and its application to K → 2π.
