Context
Enables usage of PEP 563 postponed evaluation of annotations (from __future__ import annotations) towards #878 - which would otherwise break if applied, for users who attempt to install and run the latest releases using Python 3.6.
Upgrading enables removal of attrs dependency through migration to the 3.7+ native dataclasses (PEP 557) without installing backports and which provides improved type hinting and associated IDE support towards #878 - provided there are no constraints on retaining attrs.
