10.1.0
------

Backwards Incompatible Changes
==============================

Setting image mode
^^^^^^^^^^^^^^^^^^

If you attempt to set the mode of an image directly, e.g.
``im.mode = "RGBA"``, you will now receive an ``AttributeError``. This is
not about removing existing functionality, but instead about raising an
explicit error to prevent later consequences. The ``convert`` method is the
correct way to change an image's mode.

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

Accept a list in getpixel()
^^^^^^^^^^^^^^^^^^^^^^^^^^^

py:meth:`~PIL.Image.Image.getpixel` now accepts a list of coordinates, as well
as a tuple. ::

    from PIL import Image
    im = Image.new("RGB", (1, 1))
    im.getpixel((0, 0))
    im.getpixel([0, 0])

BoxBlur and GaussianBlur allow for different x and y radii
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

py:meth:`~PIL.ImageFilter.BoxBlur` and py:meth:`~PIL.ImageFilter.GaussianBlur`
now allow a sequence of x and y radii to be specified, rather than a single
number for both dimensions. ::

    from PIL import ImageFilter
    ImageFilter.BoxBlur((2, 5))
    ImageFilter.GaussianBlur((2, 5))

API Additions
=============

has_transparency_data
^^^^^^^^^^^^^^^^^^^^^

Images now have :py:attr:`~PIL.Image.Image.has_transparency_data` to indicate
whether the image has transparency data, whether in the form of an alpha
channel, a palette with an alpha channel, or a "transparency" key in the
:py:attr:`~PIL.Image.Image.info` dictionary.

Even if this attribute is true, the image might still appear solid, if all of
the values shown within are opaque.

Other Changes
=============

Added support for DDS BC5U and 8-bit color indexed images
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Support has been added to read BC5U DDS files as RGB images, and
PALETTEINDEXED8 DDS files as P mode images.

Support reading signed 8-bit YCbCr TIFF images
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

TIFF images with unsigned integer data, 8 bits per sample and a photometric
interpretation of YCbCr can now be read.
