 PyO3 supports Python 3.5 and up. The minimum required Rust version is 1.39.0.

-PyPy is also supported (via cpyext) for Python 3.5 only, targeted PyPy version is 7.0.0.
+Building with PyPy is also possible (via cpyext) for Python 3.6, targeted PyPy version is 7.3+.
 Please refer to the [pypy section in the guide](https://pyo3.rs/master/pypy.html).

 You can either write a native Python module in Rust, or use Python from a Rust binary.
