3.3.0
-----
Libimagequant support
=====================
There is now support for using libimagequant as a higher quality
quantization option in ``Image.quantize()`` on Unix-like
platforms. This support requires building Pillow from source against
libimagequant. We cannot distribute binaries due to licensing
differences.
New Setup.py options
====================
There are two new options to control the ``build_ext`` task in ``setup.py``:
* ``--debug`` dumps all of the directories and files that are
checked when searching for libraries or headers when building the
extensions.
* ``--disable-platform-guessing`` removes many of the directories
that are checked for libraries and headers for build systems or
cross compilers that specify that information in via environment
variables.
Image Metadata
==============
The return type for binary data in version 2 Exif and Tiff metadata
has been changed from a tuple of integers to bytes. This is a change
from the behavior since ``3.0.0``.
