"Python 2.8 is a backwards-compatible Python interpreter with new 
features from Python 3.x. It was produced by forking Python 2.7.12 and 
backporting some of the new syntax, builtins, and libraries from Python 
3. Python code and C-extensions targeting Python 2.7 or below are 
expected to run unmodified on Python 2.8 and produce the same output. 
But with Python 2.8, that code can now use some of the new features from 
Python 3.x."

Backported features:

  * Function annotations
  * Keyword-only arguments
  * async / await
  * no-argument super()
  * new metaclass syntax
  * yield from
  * typing module
  * inspect.signature()
  * matrix multiplication operator
  * fine-grained reworking of OSError
  * underscores in numeric literals
  * concurrent.futures
  * types.MappingProxyType
  * selectors module
