API Additions
=============
ImageDraw.circle
^^^^^^^^^^^^^^^^
Added :py:meth:`~PIL.ImageDraw.ImageDraw.circle`. It provides the same functionality as
:py:meth:`~PIL.ImageDraw.ImageDraw.ellipse`, but instead of taking a bounding box, it
takes a center point and radius.

Python 3.13 beta
^^^^^^^^^^^^^^^^
TODO
To help others prepare for Python 3.13, wheels have been built against the 3.13 beta as
a preview. This is not official support for Python 3.13, but simply an opportunity for
users to test how Pillow works with the beta and report any problems.
