  Recent progress on colour reconnection within the Pythia framework is
presented. A new model is introduced, based on the SU(3) structure of QCD and a
minimization of the potential string energy. The inclusion of the epsilon
structure of SU(3) gives a new baryon production mechanism and makes it
possible simultaneously to describe hyperon production at both $e^+e^-$ and pp
colliders. Finally, predictions for $e^+e^-$ colliders, both past and potential
future ones, are presented.
