9.3.0

Backwards Incompatible Changes

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, ...])
