RFC 5789: PATCH Method for HTTP

This looks like another April 1st RFC (but it's apparently not):

Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.

    RFC 5789 claims to make PATCH idempotent. It’s “a bit” underspecified in RFC 2068. But you’re right; they had weird ideas before ;)
