Hi all,

Cython 0.27 is finally out, with several fixes even since the release
candidate. This is a major feature release that implements most of the new
functionality in Python 3.6, as well as some long awaited Cython language


These are the major new features:

- PEP 484/526 annotation typing
- PEP 525/530 async generators
- automatic "__richcmp__()" generation from "__eq__()" & friends
- support for Python object references in C++ classes
- PGO compilation mode in Jupyter notebooks

Plus many little enhancements and bug fixes. For a longer list of
improvements, see the changelog:


Hope you like it.
