pytypes 1.0 beta 3 has been released.

The most notable new feature is enhanced support for TypeVars.
Besides this it is mainly a bugfix release.

pytypes is a toolbox for PEP-484 style typing, explicitly supporting
Python >= 3.3, Python 2.7, Jython >= 2.7.1, PyPy 3.

Its main features include:

- Runtime typechecking

- Auto-annotating code from runtime observations in form of stubfiles

- Utility functions:
  * PEP 484 aware subtype and instance checking: is_of_type(obj, tp) and is_subtype(subtype, supertype)
  * get_type_hints that takes stubfiles and type comments into account

- Typesafe method overriding

- Pull type information from stubfiles or type comments into __annotations__ for use by other tools

- support for all versions of typing module

- support for Python 2.7, 3.3, 3.4, 3.5, 3.6, Jython 2.7.1, PyPy

- all features smoothly work with OOP, i.e. methods, static methods, class methods, properties

pytypes is still in beta phase. File issues as the occur. Help is welcome!
