@radarhere Are you okay to do this one?

[radarhere]

Yep.

[hugovk]

Are we doing the release already today (31 June) or tomorrow (1 July)? Fine either way for me :)

[radarhere]

@hugovk I started, then stopped and wondered if I was doing it too early. However, in an hour and twenty minutes, it will be the 1st in UTC +14, so as long as I'm not finished before then...

Turns out there is a problem when pillow-wheels tries to upload PyPy wheels

• Skipping Pillow-7.2.0-pp36-pypy36_pp73-macosx_10_10_x86_64.whl: Invalid or unsupported Python version tag in filename Pillow-7.2.0-pp36-pypy36_pp73-macosx_10_10_x86_64.whl - https://travis-ci.org/github/python-pillow/pillow-wheels/jobs/703441814#L5518
• Skipping Pillow-7.2.0-pp36-pypy36_pp73-manylinux2010_x86_64.whl: Invalid or unsupported Python version tag in filename Pillow-7.2.0-pp36-pypy36_pp73-manylinux2010_x86_64.whl - https://travis-ci.org/github/python-pillow/pillow-wheels/jobs/703441815#L6132

Looks like wheelhouse-uploader just doesn't support PyPy - https://github.com/ogrisel/wheelhouse-uploader/blob/01ee128247a2284813c84ab9d8cd48105f2d9e06/wheelhouse_uploader/utils.py#L120-L131

I've uploaded the rest of the files to PyPI.

I've uploaded the rest of the files to PyPI.

Good find, I've created ogrisel/wheelhouse-uploader#37 to help wheelhouse-uploader to support PyPy.

[hugovk]

Thanks for the release!

[hugovk]

And the macOS and manylinux 7.2.0 wheels for PyPy are now available on PyPI!
