A new fit is done to obtain numerical values for the order $p^4$low-energy-constants $L_i^r$ in Chiral Perturbation Theory. This includes bothnew data and new calculated observables. We take into account masses, decayconstants, $K_{\ell4}$, $\pi\pi$ and $\pi K$ scattering lengths and slopes andthe slope of the pion scalar formfactor. We compare in detail where the changesw.r.t. to the 10 year old "fit 10" come from. We discuss several scenarios forestimating the order $p^6$ constants $C_i^r$ and search for possible values ofthem that provide a good convergence for the ChPT series. We present two suchsets. One big change is that the fits do not have the expected behaviour in thelimit of large $N_c$ as well as before.
