The keynote specified that it's backwards compatible to 13. It was introduced in 13.4 but Apple didn't talk about it until now. Some developers found it in previous iOS betas but weren't sure what it was for. I'm presuming it was out earlier for testing with cars in development before iOS 14 came out. (and it's still not out)
