  This review addresses the practical convergence of the ChPT series in the
p-regime. In the SU(2) framework there is a number of new results, and improved
estimates of \bar\ell_3 and \bar\ell_4 are available. In the SU(3) framework
few new lattice computations have appeared and the improvement in the precision
of the low-energy constants L_i is comparatively slow. I sketch some of the
convergence issues genuine to extensions of ChPT which include additional
sources of chiral symmetry breaking (finite lattice spacing) and/or violations
of unitarity (different sea and valence quark masses). Finally, it is pointed
out that the quark mass ratios m_u/m_d, m_s/m_d happen to be such that no
reordering of the chiral series is needed to accommodate the experimental pion
and kaon masses.
