# Added availableModelsMatch and deniedModels managed settings for precise model version control

> New managed settings allow organizations to pin exact model versions with availableModelsMatch set to 'exact', requiring explicit allowlisting before new model releases can be used. deniedModels blocks specific models even when generally allowed, enabling stricter governance over model deployments.
