A controlled chiral extrapolation of these lattice results to the physical point suggested that the state, identified with the famed H dibaryon, is most likely slightly unbound (by 13 $\\pm$ 14 MeV) with respect to the $\\Lambda--\\Lambda$ threshold. We report the results of an updated analysis which finds the H unbound by 26 $\\pm$ 11 MeV.
