N2 - We briefly overview the historical controversy around Standard Model predictions of ϵ ′/ϵ and clarify the underlying physics. A full update of this important observable is presented, with all known short-and long-distance contributions, including isospin-breaking corrections. The current Standard Model prediction, Re(ϵ ′/ϵ) = (14 ± 5) • 10-4 [1, 2], is in excellent agreement with the experimentally measured value.
