When people talk about "the new files API" (#1764), is there some online documentation which shows its differences versus the "old API"?

Or is it the same API (same access point, same documentation), where some things have changed along time ... so an old script could now be failing because of the changes?

I have just discovered Zenodo and this is the only documentation I found. But it doesn't say it is new or old:
