What is the different between feature and endpoint in elasticsearch?

What is the different between feature and endpoint in elasticsearch?

I have try with

GET my_index/_mappings

or

GET my_index/_mapping

and both return same result

Looking at the source code of RestGetMappingAction, they are merely synonyms and handled the same way.

I think both are still there for backward compatibility's sake.
