The NA48 experiment, conceived primarily to look for direct CP violation in neutral kaon decays, has recently published the so far most precise determination of the epsilon'/epsilon parameter. After reviewing shortly this result, we report on the 2001 data-taking, which concluded the epsilon' program by collecting a substantial amount of data with different beam intensity conditions. We also present new precision measurements of the K0 and eta masses and of the K-short lifetime, that provide consistency checks of our analysis. Finally, the prospects for the future experimental program are discussed.
