• python-pillow/pillow-wheels#175

Ok, I've created #5133

[hugovk]

@radarhere Are you up for this one?

[radarhere]

@hugovk sure, I can do that. Would you mind merging in the security-related items first? You've been more across that than I have.

[radarhere]

@wiredfool should I continue going ahead with this release, or wait for #5062?

[wiredfool]

I would have liked #5602 to get in, because I think it's potentially a fix for a pretty serious issue, but we are looking at sending a pretty significant change out without decent smoke testing there.

[radarhere]

Thanks.

@cgohlke could we have Windows binaries for 8.1.0?

[nulano]

One significant change in #5062, if/when it makes it in, is that it removes support for dynamically loading Raqm, which will require all Windows users to switch from installing libraqm.dll to fribidi.dll.

[radarhere]

Thanks.

And we're done - https://twitter.com/PythonPillow/status/1345465680028569600

We had disabled Travis to conserve credits (#5028 (comment)), shall we chance building manylinux aarch64 wheels with the remaining credits?

• Remove 'latest' jobs from Travis CI to build aarch64 wheels pillow-wheels#182

[wiredfool]

Might as well try.

✅ Merged python-pillow/pillow-wheels#182
✅ Triggered https://travis-ci.com/github/python-pillow/pillow-wheels/builds/212162757
✅ Wheels built and uploaded as to https://github.com/python-pillow/pillow-wheels/releases/tag/untagged-16ee6820e47366c4ca5b
✅ Now at 1100 credits remaining, down from 2250? We should have one more build left until we're out.
👉 Show up as "untagged" on GH because the build wasn't a tag build, I think that's fine and the wheel files themselves look correctly versioned
👉 Would someone be able to test one of those before we upload to PyPI?

Testing on GHA with aptman/qus mostly OK, fails at Image.show test (probably no viewer is available): https://github.com/nulano/Pillow/runs/1655645234?check_suite_focus=true

Edit: Disabling fast-fail, there are also two failures due to missing extra test images, everything else passes: https://github.com/nulano/Pillow/runs/1655692661?check_suite_focus=true#step:7:1751
