It is an update to PEP 484, adding support for type-checking decorators.

https://www.python.org/dev/peps/pep-0484/

I don't understand what you mean by "what type is it".

When does it happen: if there are no strong or conclusive objections
(and I don't think there have been) it may have already happened by now.
If not, then soon. Depends on Guido's schedule.

As for when it will actually be visible in Python, the original post 
already answered that: Guido hopes to add it to Python 3.6.2 and 3.5.4. 
I don't think this will have much visible impact unless you're using 
MyPy for type checking.

By the way, the original post was less than fifty lines. That already 
is a summary.
