11.0.0
------
Backwards Incompatible Changes
==============================
Python 3.8
^^^^^^^^^^
Pillow has dropped support for Python 3.8,
which reached end-of-life in October 2024.
Python 3.12 on macOS <= 10.12
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The latest version of Python 3.12 only supports macOS versions 10.13 and later,
and so Pillow has also updated the deployment target for its prebuilt Python 3.12
wheels.
PSFile
^^^^^^
The :py:class:`!PSFile` class was removed in Pillow 11 (2024-10-15).
This class was only made as a helper to be used internally,
so there is no replacement. If you need this functionality though,
it is a very short class that can easily be recreated in your own code.
PyAccess and Image.USE_CFFI_ACCESS
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Since Pillow's C API is now faster than PyAccess on PyPy, ``PyAccess`` has been
removed. Pillow's C API will now be used on PyPy instead.
``Image.USE_CFFI_ACCESS``, for switching from the C API to PyAccess, was
similarly removed.
TiffImagePlugin IFD_LEGACY_API
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
An unused setting, ``TiffImagePlugin.IFD_LEGACY_API``, has been removed.
WebP 0.4
^^^^^^^^
Support for WebP 0.4 and earlier has been removed; WebP 0.5 is the minimum supported.
Deprecations
============
FreeType 2.9.0
^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
Support for FreeType 2.9.0 is deprecated and will be removed in Pillow 12.0.0
(2025-10-15), when FreeType 2.9.1 will be the minimum supported.
We recommend upgrading to at least FreeType `2.10.4`_, which fixed a severe
vulnerability introduced in FreeType 2.6 (:cve:`2020-15999`).
.. _2.10.4: https://sourceforge.net/projects/freetype/files/freetype2/2.10.4/
Get internal pointers to objects
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
``Image.core.ImagingCore.id`` and ``Image.core.ImagingCore.unsafe_ptrs`` have been
deprecated and will be removed in Pillow 12 (2025-10-15). They were used for obtaining
raw pointers to ``ImagingCore`` internals. To interact with C code, you can use
``Image.Image.getim()``, which returns a ``Capsule`` object.
ICNS (width, height, scale) sizes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
Setting an ICNS image size to ``(width, height, scale)`` before loading has been
deprecated. Instead, ``load(scale)`` can be used.
Image isImageType()
^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
``Image.isImageType(im)`` has been deprecated. Use ``isinstance(im, Image.Image)``
instead.
ImageMath.lambda_eval and ImageMath.unsafe_eval options parameter
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
The ``options`` parameter in :py:meth:`~PIL.ImageMath.lambda_eval()` and
:py:meth:`~PIL.ImageMath.unsafe_eval()` has been deprecated. One or more
keyword arguments can be used instead.
JpegImageFile.huffman_ac and JpegImageFile.huffman_dc
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
The ``huffman_ac`` and ``huffman_dc`` dictionaries on JPEG images were unused. They
have been deprecated, and will be removed in Pillow 12 (2025-10-15).
Specific WebP Feature Checks
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. deprecated:: 11.0.0
``features.check("transp_webp")``, ``features.check("webp_mux")`` and
``features.check("webp_anim")`` are now deprecated. They will always return
``True`` if the WebP module is installed, until they are removed in Pillow
12.0.0 (2025-10-15).
API Changes
===========
Default resampling filter for I;16* image modes
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The default resampling filter for I;16, I;16L, I;16B and I;16N has been changed from
``Image.NEAREST`` to ``Image.BICUBIC``, to match the majority of modes.
API Additions
=============
Writing XMP bytes to JPEG and MPO
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
XMP data can now be saved to JPEG files using an ``xmp`` argument::
im.save("out.jpg", xmp=b"test")
The data can also be set through :py:attr:`~PIL.Image.Image.info`, for use when saving
either JPEG or MPO images::
im.info["xmp"] = b"test"
im.save("out.jpg")
Other Changes
=============
Python 3.13
^^^^^^^^^^^
Pillow 10.4.0 had wheels built against Python 3.13 beta, available as a preview to help
others prepare for 3.13, and to ensure Pillow could be used immediately at the release
of 3.13.0 final (2024-10-07, :pep:`719`).
Pillow 11.0.0 now officially supports Python 3.13.
Support has also been added for the experimental free-threaded mode of :pep:`703`.
Python 3.13 only supports macOS versions 10.13 and later.
C-level Flags
^^^^^^^^^^^^^
Some compiling flags like ``WITH_THREADING``, ``WITH_IMAGECHOPS``, and other
``WITH_*`` were removed. These flags were not available through the build system,
but they could be edited in the C source.
