API Changes
===========

TODO
^^^^
Added alpha_quality argument when saving WebP images
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

TODO
When saving WebP images, an ``alpha_quality`` argument can be passed to the encoder. It
is an integer value between 0 to 100, where values other than 100 will provide lossy
compression.

Negative kmeans error
^^^^^^^^^^^^^^^^^^^^^

When calling :py:meth:`~PIL.Image.Image.quantize`, a negative ``kmeans`` will now
raise a :py:exc:`ValueError`, unless a palette is supplied to make the value redundant.

Negative P1-P3 PPM value error
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If a P1-P3 PPM image contains a negative value, a :py:exc:`ValueError` will now be
raised.
