[-]Add support for Python 3.11[/-][+]Add support for Python 3.12[/+]on Feb 11, 2023 - pinned this issue
on Apr 11, 2023 deadsnakes decided not to support Python 3.12 on Bionic, the last 32-bit Ubuntu. We've discussed dropping support for 32-bit briefly before, so the simplest thing is for us to not release 32-bit Linux Python 3.12 wheels.
That should be fine.
Looking at a couple of projects:
We (NumPy) will continue to test (but not provide wheels for) 32-bit linux.
We [pyca/cryptography] stopped testing on 32-bit Linux, and stopped building 32-bit Linux wheels several years ago, and that produced no problems.

Looking at some numbers, here's a week's worth of Pillow file downloads from PyPI, fetched using https://github.com/ofek/pypinfo:
pypinfo --days 7 --limit 1000 pillow version fileFiltering for the most recent release, for Python 3.11, and Linux (
grep "9.5.0-cp311.*linux" 1000.txt) shows a very small number for i686:version file download_count percentage 9.5.0 Pillow-9.5.0-cp311-cp311-manylinux_2_28_x86_64.whl 219,628 91.71 % 9.5.0 Pillow-9.5.0-cp311-cp311-manylinux_2_28_aarch64.whl 7,407 3.09 % 9.5.0 Pillow-9.5.0-cp311-cp311-musllinux_1_1_x86_64.whl 5,810 2.43 % 9.5.0 Pillow-9.5.0-cp311-cp311-manylinux_2_17_x86_64.manylinux2014_x86_64.whl 5,233 2.19 % 9.5.0 Pillow-9.5.0-cp311-cp311-musllinux_1_1_aarch64.whl 771 0.32 % 9.5.0 Pillow-9.5.0-cp311-cp311-manylinux_2_17_aarch64.manylinux2014_aarch64.whl 405 0.17 % 9.5.0 Pillow-9.5.0-cp311-cp311-manylinux_2_17_i686.manylinux2014_i686.whl 226 0.09 % total 239,480 100.00 % Whilst we're here, Windows is quite low for win32:

Reacted by Hugo van KemenadeSounds good.
So let's not create 32-bit wheels for 3.12. Do we still want to test 32-bit for 3.12?
The next Pillow 10.0.0 is a major bump so it's a good opportunity to drop things:
-
For 3.11, shall we drop 32-bit wheels and/or testing?
-
And older ones, 3.10-3.8?

python-pillow/pillow-wheels#383 has added Python 3.12 macOS and Linux wheels, excluding 32-bit wheels, and albeit without fribidi, harfbuzz and raqm on macOS until #7167 is resolved.
Pillow-9.5.0 works well on Python 3.12.0b2 on Windows:

I suggest we drop all the 32-bit wheels and testing. If there's a lot of demand or very good reason, we can always add something back (e.g. 3.8 on Windows has a slightly larger percentage).
Sorry, I'm on holiday here so this is a little late --
I'm not sure if there are any remaining platforms were 32 bit is really a going concern, but I'd view it as a minor platform in the same way that we support S390 or Big Endian -- good to keep compatibility with from a correctness POV, but we're not building wheels. There's nothing in 32 bit to my knowledge where dropping it really streamlines our code.
Okay, let's keep some representative testing of 32-bit on the CI. I'd say we can leave the docker-images changes as is.
There's nothing in 32 bit to my knowledge where dropping it really streamlines our code.
Yeah, #7228 was mostly test bits and pieces.
We later also restored a Windows 32-bit job - #7234 (comment)

on Jun 4, 2024 Hi!
is there a plan to release a wheel for Pillow 9.5 with python 3.12? Plone, for example, uses Pillow and supports python 3.12 but still reference Pillow 9.5.0. Thanks for any info!Hi. There isn't a plan to do so, no. In general, we would encourage you to upgrade to the latest version of Pillow to receive recent security fixes.
