Abstract
The recent release of improved lattice data has revived again the interest on precise theoretical calculations of the direct CP-violation ratio $\varepsilon'/\varepsilon$. We present a complete update of the Standard Model prediction [1,2], including a new re-analysis of isospin-breaking corrections which are of vital importance in the theoretical determination of this observable. The Standard Model prediction, $\mathrm{Re} (\epsilon'/\epsilon) = (14\pm 5)\cdot 10^{-4}$, turns out to be in good agreement with the experimental measurement.
