We present a concise overview on CP violation in hyperon decays, including past, present, and future efforts to search for it. We highlight in particular the most recent results of the BESIII experiment using a quantum-entangled pair of hyperon and antihyperon produced by a charmonium resonance formed in e+e- annihilation. The subsequent nonleptonic decays of these hyperon pairs allow for the simultaneous determination of various parameters pertaining to CP violation in the decays. We compare the reported data with the corresponding current predictions for CP asymmetries within the standard model of particle physics. Moreover, we touch on how much these asymmetries might be enhanced by possible new physics beyond the standard model. We also comment briefly on the importance of the proposed super tau-charm factories in future quests for hyperon CP-violation.
