Requests maintainer Nate Prewitt is planning to add support for type hints to Requests in the next three months. Right now the feature is available as a development branch but will later be published to PyPI as a pre-release version. The goal is to find and fix issues before rolling the change out to users to avoid unnecessary breakage.

Shipping large changes to codebases this popular is difficult without breaking users. This is where you come in: Requests needs your help! If your project or application uses Requests as a dependency, try installing and running the development branch with type hints. This is especially useful if your project uses type hints and a type checker like Mypy, Pyright, or Ty.
