Python 2.6 and 3.2 Dropped¶
Pillow 4.0 no longer supports Python 2.6 and 3.2. We will not be creating binaries, testing, or retaining compatibility with these releases. This release removes some workarounds for those Python releases, so the final working version of Pillow on 2.6 or 3.2 is 3.4.2.
Support added for Python 3.6¶
Pillow 4.0 supports Python 3.6.
OleFileIO.py has been removed as a vendored file and is now installed
from the upstream olefile pypi package. All internal dependencies are
redirected to the olefile package. Direct accesses to
PIL.OlefileIO raises a deprecation warning, then patches the
upstream olefile into
sys.modules in its place.
SGI image save¶
It is now possible to save images in modes
RGBA to the uncompressed SGI image format.
Zero sized images¶
Pillow 3.4.0 removed support for creating images with (0,0) size. This has been reenabled, restoring pre 3.4 behavior.
Internal handles_eof flag¶
handles_eof flag for decoding images has been removed, as there
were no internal users of the flag. Anyone maintaining image decoders
outside of the Pillow source tree should consider using the cleanup
function pointers instead.
The stretch function on the core image object has been removed. This used to be for enlarging the image, but has been aliased to resize recently.
