Hi @cgohlke, please could we have Windows binaries for 9.1.1?

[cgohlke]

Here you go. You may not want to upload the wheels for Python 3.11b1 to PyPI.

[hugovk]

@cgohlke Thank you! Yep, I skipped the 3.11 beta ones. Nice to see they're building though :)

For 3.10 last year, we were going to do our October release as soon as 3.10 was released, but then decided to put out 3.10 wheels already during the RC period to help people test: #5569 (comment). So I expect we'll do something similar this year.

3.11 schedule:

• 3.11.0 beta 2: Monday, 2022-05-30
• 3.11.0 beta 3: Thursday, 2022-06-16
• 3.11.0 beta 4: Saturday, 2022-07-09
• 3.11.0 candidate 1: Monday, 2022-08-01
• 3.11.0 candidate 2: Monday, 2022-09-05
• 3.11.0 final: Monday, 2022-10-03

(Maybe even include a 3.11 in the July release? Anyway, we can discuss this stuff later.)

Installing 9.1.1 under python:3.10.4-slim-bullseye (M1 cpu) fails with the error below but 9.1.0 works fine. I'm not sure if this is something that went wrong with the release or a bug in the code.

It's trying a source build there.

If you install 9.1.0 with no cache, does it install a wheel?

For example, what output do you get with this?

python3 -m pip install --no-cache-dir pillow==9.1.0

Thanks, we're missing the aarch64 wheels, the others are built on GitHub Actions but these are built by Travis CI and for some reason didn't upload to GitHub Releases (and from there to PyPI):

https://app.travis-ci.com/github/python-pillow/pillow-wheels/builds/250747395

We'll look into it.

Seems okay now. Thanks a lot.

Thanks all! Pinned Tweet is up.

Issue python-pillow/pillow-wheels#295 and PR python-pillow/pillow-wheels#296 to help release aarch64 wheels for next time.
