Thank you Yury and Elvis for working on this! I have few more suggestions for What's New: * collections.abc.Reversible (http://bugs.python.org/issue25987). * various ABCs in collections.abc now have means for explicit "anti-registration" by setting a corresponding attribute to None (http://bugs.python.org/issue25958, https://docs.python.org/3.6/reference/datamodel.html#special-method-names). * implementation improvements (such as caching of generic types) in typing module give up to 30x seep-up and reduce memory footprint. * typing.py now supports generic type aliases (https://github.com/python/typing/pull/195 and https://github.com/python/typing/pull/308, see mypy docs for usage examples). * typing.py supports PEP 526 syntax for typed NamedTuple (https://github.com/python/typing/pull/282). (I see that there are already several items about typing, so please feel free to keep only the most important changes.)
