Missing N1QL REST API documentation for 4.1

There is a N1QL REST API for Couchbase Server 4.1.

It is documented in the 4.0 docs: http://developer.couchbase.com/documentation/server/4.0/n1ql/n1ql-rest-api/index.html

It is documented in the 4.5 docs: http://developer.couchbase.com/documentation/server/4.5/n1ql/n1ql-rest-api/index.html

But I can't find the documentation in the 4.1 docs.

(I don't know if there are any differences in the N1QL REST API between 4.0 and 4.1).
