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

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

Allow default ImageDraw font to be set
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Rather than specifying a font when calling text-related ImageDraw methods, or
setting a font on each ImageDraw instance, the default font can now be set for
all future ImageDraw operations::

    from PIL import ImageDraw, ImageFont
    ImageDraw.ImageDraw.font = ImageFont.truetype("Tests/fonts/FreeMono.ttf")

Saving multiple MPO frames
^^^^^^^^^^^^^^^^^^^^^^^^^^

Multiple MPO frames can now be saved. Using the ``save_all`` argument, all of
an image's frames will be saved to file::

    from PIL import Image
    im = Image.open("frozenpond.mpo")
    im.save(out, save_all=True)

Additional images can also be appended when saving, by combining the
``save_all`` argument with the ``append_images`` argument::

    im.save(out, save_all=True, append_images=[im1, im2, ...])


Security
========

Decode JPEG compressed BLP1 data in original mode
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Within the BLP image format, BLP1 data may use JPEG compression. Instead of
telling the JPEG library that this data is in BGRX mode, Pillow will now
decode the data in its natural CMYK mode, then convert it to RGB and rearrange
the channels afterwards. Trying to load the data in an incorrect mode could
result in a segmentation fault. This issue was introduced in Pillow 9.1.0.

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

Added DDS ATI1, ATI2 and BC6H reading
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Support has been added to read the ATI1, ATI2 and BC6H formats of DDS images.

Show all frames with ImageShow
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

When calling :py:meth:`~PIL.Image.Image.show` or using
:py:mod:`~PIL.ImageShow`, all frames will now be shown.
