Python Changes
--------------

Packaging
~~~~~~~~~

-  Dropped support for Python 3.6 and added support for Python 3.9
   (`#246 <https://github.com/dhermes/bezier/pull/246>`__).

Documentation
~~~~~~~~~~~~~

-  Typo fix in ``BEZ_curve_intersections`` (C ABI) for the upper bound on
   ``intersections_size``
   (`#232 <https://github.com/dhermes/bezier/pull/232>`__).
   H/T to `@KIKI007 <https://github.com/KIKI007>`__.
-  Adding documentation for the ``BEZIER_DLL_HASH`` environment variable
   (`#239 <https://github.com/dhermes/bezier/pull/239>`__). This environment
   variable is an escape hatch used during build and testing; it does not apply
   to ``bezier`` at runtime.

Breaking Changes
~~~~~~~~~~~~~~~~

-  Moved non-public / experimental ``bezier._clipping`` module to
   ``bezier.hazmat.clipping``
   (`#225 <https://github.com/dhermes/bezier/pull/225>`__).
-  Removed normalization from
   ``bezier.hazmat.clipping.compute_implicit_line()``
   (`#233 <https://github.com/dhermes/bezier/pull/233>`__). This avoided
   unnecessary flops and allowed the ``clip_range()`` docstring example to
   produce an exact answer instead of an approximate one.
