In the recent year many new results from kaon decays have been reported from both the NA48 experiment at CERN and the KTeV experiment at Fermilab. Both experiments have new and improved measurements of the parameter Re(epsilon'/epsilon) of direct CP violation in the neutral kaon system. Also several new results on rare and very rare K_L decays were reported. In addition, the NA48 collaboration has performed special high-intensity K_S run periods, with the first results now being available.
