Released: September 17, 2021

bug

[bug] [typing] Added missing attributes from context stubs.

References: #900
[bug] [mypy] Fixed an import in one of the .pyi files that was triggering an
assertion error in some versions of mypy.

References: #897
[bug] [ops] [regression] Fixed issue where registration of custom ops was prone to failure due to
the registration process running exec() on generated code that as of
the 1.7 series includes pep-484 annotations, which in the case of end user
code would result in name resolution errors when the exec occurs. The logic
in question has been altered so that the annotations are rendered as
forward references so that the exec() can proceed.
