 Several versions of the Python interpreter are available on Nix, as well as a
 high amount of packages. The attribute `python3` refers to the default
-interpreter, which is currently CPython 3.8. The attribute `python` refers to
+interpreter, which is currently CPython 3.9. The attribute `python` refers to
 CPython 2.7 for backwards-compatibility. It is also possible to refer to
 specific versions, e.g. `python38` refers to CPython 3.8, and `pypy` refers to
 the default PyPy interpreter.
