There is new minor version of json-rpc library I developed during last month.
Little bit than one month ago I realised, that there are no convenient implementations of json-rpc transport specification for python. None of them supports python3, moreover all of the libraries work with JSON-RPC 2.0.
This realisation supports both JSON-RPC standards, works with python2 and python3, has syntactic sugar and does not implement anything else, such as server of client. Welcome everybody to test it!
