Abstract//

The decay of the eta meson to three pions is directly related to the 
light quark mass difference (mu-md). A good understanding of this decay 
would give a constraint on the light quark masses. However, at the 
moment there are considerable discrepancies between data and theoretical 
calculations. More data, with high statistics and detailed kinematic 
dependence, can give insight into these discrepancies and even be used 
as input for new theoretical calculations. In this talk I will present 
analysis of the Dalitz plot from the world largest data set of 
eta->pi+pi-pi0 decays collected at the KLOE detector. I will also give a 
short status of the upgraded KLOE detector, KLOE-2, and the ongoing 
experimental run at DAFNE e+e- collider.
