*   The C API type `TF_SessionWithGraph` has been renamed to `TF_Session`,
    indicating its preferred use in language bindings for TensorFlow. What was
    previously `TF_Session` has been renamed to `TF_DeprecatedSession`.
*   Renamed `TF_Port` to `TF_Output` in the C API.
*   Removes RegisterShape from public API. Use C++ shape function registration
    instead. indexing now starts from 1 instead of 0, and `bus_id==0` is used
