+with a ``dtype`` argument.
+
+.. code-block:: pycon
+
+    >>> from PIL import Image
+    >>> import numpy
+    >>> im = Image.new("RGB", (100, 100))
+    >>> numpy.array(im, dtype=numpy.float64)

+    TypeError: __array__() takes 1 positional argument but 2 were given
+    >>>
+
+Catch OSError when checking if destination is sys.stdout
+========================================================
+
+In 8.3.0, a check to see if the destination was ``sys.stdout`` when saving an image was
+updated. This lead to an OSError being raised if the environment restricted access.
+
+The OSError is now silently caught.
+
+Fixed removing orientation in ImageOps.exif_transpose
+=====================================================
+
+In 8.3.0, :py:meth:`~PIL.ImageOps.exif_transpose` was changed to ensure that the
+original image EXIF data was not modified, and the orientation was only removed from
+the modified copy.
+
+However, for certain images the orientation was already missing from the modified
+image, leading to a KeyError.
+
+This error has been resolved, and the copying of metadata to the modified image
+improved.

+
+Python 3.10 wheels
+^^^^^^^^^^^^^^^^^^
+
+Pillow now includes binary wheels for Python 3.10.
+
+The Python 3.10 release candidate was released on 2021-08-03 with the final release due
+2021-10-04 (:pep:`619`). The CPython core team strongly encourages maintainers of
+third-party Python projects to prepare for 3.10 compatibility. And as there are `no ABI
+changes`_ planned we are releasing wheels to help others prepare for 3.10, and ensure
+Pillow can be used immediately on release day of 3.10.0 final.
+
+Fixed regressions
+^^^^^^^^^^^^^^^^^
+
+* Ensure TIFF ``RowsPerStrip`` is multiple of 8 for JPEG compression (:pr:`5588`).
+
+* Updates for :py:class:`~PIL.ImagePalette` channel order (:pr:`5599`).
+
+* Hide FriBiDi shim symbols to avoid conflict with real FriBiDi library (:pr:`5651`).

+API Changes
+===========
+
+Deprecations
+^^^^^^^^^^^^
+
+ImagePalette size parameter
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``size`` parameter will be removed in Pillow 10.0.0 (2023-01-02).
+
+Before Pillow 8.3.0, ``ImagePalette`` required palette data of particular lengths by
+default, and the size parameter could be used to override that. Pillow 8.3.0 removed
+the default required length, also removing the need for the size parameter.
+
+API Additions
+=============
+
+Added "transparency" argument for loading EPS images
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This new argument switches the Ghostscript device from "ppmraw" to "pngalpha",
+generating an RGBA image with a transparent background instead of an RGB image with a
+white background.
+
+.. code-block:: python
+
+    with Image.open("sample.eps") as im:
+        im.load(transparency=True)
+
+Added WalImageFile class
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+:py:func:`PIL.WalImageFile.open()` previously returned a generic
+:py:class:`PIL.Image.Image` instance. It now returns a dedicated
+:py:class:`PIL.WalImageFile.WalImageFile` class.
+
+Security
+========
+
+TODO
+^^^^

+
+Other Changes
+=============
+
+Speed improvement when rotating square images
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Starting with Pillow 3.3.0, the speed of rotating images by 90 or 270 degrees was
+improved by quickly returning :py:meth:`~PIL.Image.Image.transpose` instead, if the
+rotate operation allowed for expansion and did not specify a center or post-rotate
+translation.
+
+Since the ``expand`` flag makes no difference for square images though, Pillow now
+uses this faster method for square images without the ``expand`` flag as well.
