- Primary and lowest eT dielectron trigger (with L1_2EM15VHI seed (previously unavailable))
- Single photon trigger g120_loose_L1EM22VHI
- Updated configuration for athenaMT monitoring to include new electron and photon isolated chains discussed in ATR-20756
- Updated configuration also in legacy monitoring missing in 8th round validation (ATR-21986)
