I wonder if the fix is to upgrade the Pillow version to the latest release: https://github.com/python-pillow/Pillow/releases/tag/11.1.0?

I wonder if the fix is to upgrade the Pillow version to the latest release: https://github.com/python-pillow/Pillow/releases/tag/11.1.0?

This does seem to fix the problem on my local branch. Could anyone point me towards any resources that would help me to make this fix correctly so I can make a PR out of it?

I want to change the file
build/pkgs/pillow/package-version.txt
to update the version number and make the corresponding changes to the checksums in
build/pkgs/pillow/checksums.ini

But I am unsure where to get the correct checksums from, and where to point the code to download the new tarball from. @dimpase do you have any advice?

we already have a positively reviewed PR bumping up pillow and cffi to the versions good for Python 3.13.
