The paper reports first magnetic measurements performed on MBE grown epilayers of zinc-blende Cd_{1-x}Mn_{x}Se. For all samples studied in the concentration range 0.24 < x < 0.63 we find at low temperatures a history-dependent magnetic response, suggesting a transition to a spin-glass-like state. The central result of the paper is the presentation of a new, complete magnetic phase diagram for this material.
