Several changes have been made for the run 3 migration, two new algorithms were created, L1CaloCondAlg which is the replacement of L1CaloCondSvc for run 3 Athena, a test algorithm called L1CaloCondAlgReader which the user can run and check the Attributes are read correctly. A new jobOption for running the l1calocondalg, located in TrigT1CaloCondSvc/python/L1CaloCondConfig.py. Condition Containers have been updated using CONDCONT_DEF. A new condition container was created for storing a new set of Attributes located in /TRIGGER/L1Calo/V2/Configuration/ReadoutConfigJSON.
