Sourced from aiosignal's releases.

1.4.0

Features

• Added decorator functionality to Signal as a convenient way to add a callback -- by @Vizonex. [#699](https://github.com/aio-libs/aiosignal/issues/699) <https://github.com/aio-libs/aiosignal/pulls/699>_

• Improved type safety by allowing callback parameters to be type checked (typing-extensions is now required for Python <3.13).
