===============

v1.4 (2021-10-15)
-----------------

* add guidance around the use of ``Py_FindMethod`` (thanks to David Aguilar)

Fixes:

* Avoid compiler warning about unused function
* Fix ``DESTDIR`` support in the Makefile (thanks to David Aguilar)

v1.3.1 (2021-01-07)
-------------------

Packaging:

* Allow building the documentation without sphinx_rtd_theme

There is no neeed to update to 1.3.1 unless you are having trouble building
the documentation.


v1.3 (2020-11-29)
-----------------

Compatibility:

* Tested with Python 3.9.0

Additions:

* To help avoid compiler warning about uninitialized members, extra members
  are added to the ``PyModuleDef`` structure for Python 2: ``m_slots``,
  ``m_traverse``, ``m_clear`` and ``m_free``.
  Under Python 2, they must be set to NULL (usually by continuing to leave
  them out).


v1.2 (2020-06-27)
-----------------

Compatibility:

* Tests updated to pass with Python 3.9.0b3

Build:

* ``make install`` now honors DESTDIR to support staged installations


v1.1 (2019-10-04)
-----------------

Compatibility:

* Tests updated to pass with Python 3.8.0rc1
* Python versions 2.6 and 3.3 are no longer tested (due to lack of CI support)


v1.0 (2018-02-06)
-----------------

Additions:

* Add Py_UNREACHABLE from Python 3.7
* Add Py_RETURN_RICHCOMPARE from Python 3.7

Deprecations:

Tests:

-----------------

Tests:

* Adapt tests to Python 3.7 regarding const correctness (thanks to Marcel Plch)

Build:

* Fix includedir substitution on OS X (thanks to Branko Čibej)
