22.10.0

Bugfixes:

• Do not emit Y020 for empty strings. Y020 concerns "quoted annotations",
  but an empty string can never be a quoted annotation.
• Add special-casing so that Y020 is not emitted for __slots__ definitions
  inside class blocks.
• Expand Y035 to cover __slots__ definitions as well as __match_args__ and
  __all__ definitions.
• Expand Y015 so that errors are emitted for assignments to negative numbers.

Other changes:

• Since v22.8.1, flake8-pyi has emitted a FutureWarning if run with flake8<5,
  warning that the plugin would soon become incompatible with flake8<5. Due to
  some issues that mean that some users are unable to upgrade to flake8>=5,
  however, flake8-pyi no longer intends to remove support for running the
  plugin with flake8<5 before Python 3.7 has reached end-of-life. As such, the
  FutureWarning is no longer emitted.
