Fix %s and %r formatting of a greenlet on Python 2. Previously it would result in a Unicode string instead of a native string. See issue 218.
Add the ability to set a greenlet’s PEP 567 contextvars context directly, by assigning to the greenlet’s
gr_contextattribute. This restores support for some patterns of using greenlets atop an async environment that became more challenging in 0.4.17. Thanks to Joshua Oreman, Mike bayer, and Fantix King, among others. See PR 198.
The repr of greenlet objects now includes extra information about its state. This is purely informative and the details are subject to change. See issue 215.
greenletmodule is now a package. There are no API changes, so all existing imports, including from C code, should continue to work.
(C API) The undocumented
GREENLET_VERSIONmacro that defined a string giving the greenlet version is now deprecated and will not be updated.
(Documentation) Publish the change log to https://greenlet.readthedocs.io
Drop support for Python 2.4, 2.5, 2.6, 3.0, 3.1, 3.2 and 3.4. The project metadata now includes the
python_requiresdata to help installation tools understand supported versions.
Add partial support for AIX ppc64 and IBM i. Thanks to Jesse Gorzinski and Kevin Adler. See PR 197.
Require setuptools to build from source.
Stop asking setuptools to build both .tar.gz and .zip sdists. PyPI has standardized on .tar.gz for all platforms.
Stop using a custom distutils command to build extensions. distutils is deprecated.
Remove the ability to use the deprecated command
python setup.py test. Run greenlet tests with your favorite unittest-compatible test runner, e.g.,
python -m unittest discover greenlet.tests. See issue 185.
The directory layout and resulting sdists have changed. See issue 184.
greenlet is now always built with support for tracing and garbage collection, and, on Python 3.7 and above, support for context variables. The internal and undocumented C preprocessor macros that could be used to alter that at compile time have been removed (no combination other than the defaults was ever tested). This helps define a stable ABI.

Greenlet has an instance dictionary now, which means it can be used for implementing greenlet local storage, etc. However, this might introduce incompatibility if subclasses have __dict__ in their __slots__. Classes like that will fail, because greenlet already has __dict__ out of the box.
Greenlet no longer leaks memory after thread termination, as long as terminated thread has no running greenlets left at the time.
