The kaons decaying into pions offer several opportunities to study direct CP violation. One of the most famous is given by ε'/ε, but several new observables can be provided also in K → 3π. In this talk, I will review the main features and new theoretical developments of the interesting observables in K → 3π. I will focus also on the importance of final state interactions and on the technics used to calculate them. The comparison of ε'/ε and the CP-violating observables of K → 3π can help a lot to understand the relevant hadronic matrix elements and finally the consistency of the Standard Model.
