Documentation

Make sure the default version for Read the Docs is the latest release version, e.g. 3.1.x rather than latest: https://readthedocs.org/projects/pillow/versions/

@python-pillow/pillow-team How are we doing on this one folks?

@hugovk

@hugovk Any interest in driving this one? If so, let me know and I'll add you as a Maintainer to PyPI (which will allow you to upload).

Yes, can do. I'm hugovk on PyPI too.

It would be great to get the Python 3.7 wheels in:

Release wheels for latest stable for Python 3.7 #3074 issue
Add Python 3.7 pillow-wheels#90 PR, pending this:
Add Python 3.7 pillow-wheels#90 PR

Also, a PR would be good to update release notes if anyone would like to look at that.

@hugovk

@hugovk Done, thanks

I'll whip something up to pass as release notes shortly.

Done all the merging that's going to be merged for this one, will let the CIs settle then start on https://github.com/python-pillow/Pillow/blob/master/RELEASING.md.

@cgohlke

Hi @cgohlke, please could we have Windows binaries for 5.2.0? Thank you!

Here you go.

However, the tests fail and quit:

@cgohlke

Thanks @cgohlke, uploaded!

I wonder what's causing that failure, and why AppVeyor isn't also failing.

I can't reproduce this outside the tests.

Status:

Uploaded source tarball, Mac and Linux wheels, and Windows binaries.

We don't yet have Python 3.7 wheels for Mac/Linux as the wheel builder is not quite ready for 3.7 (Release wheels for latest stable for Python 3.7 #3074, Add Python 3.7 pillow-wheels#90). We can do those when they're available and building from source should be fine until then.

Manually hide old versions on PyPI such that only the latest major release is visible when viewing https://pypi.org/project/Pillow/ (https://pypi.org/manage/project/Pillow/releases/)

I think this step is no longer applicable for the new PyPI (aka Warehouse).

(a) I no longer see a list of versions at https://pypi.org/project/Pillow/. https://pypi.org/project/Pillow/#history is a reverse chronological list of all releases.
(b) I also don't have permission to access https://pypi.org/manage/project/Pillow/releases/, but given (a), I don't think it matters.

Finally, I've confirmed pip install -U pillow installs the latest 5.2.0 from wheel/binary on:

Windows 7 + Python 2.7
Ubuntu 14.04 (Trusty Tahr) + Python 2.7, 3.4-3.6
macOS High Sierra + Python 2.7

And from source on:

Ubuntu 14.04 (Trusty Tahr) + Python 3.7
macOS High Sierra + Python 3.7

Mac / Linux wheels for 3.7:

python-pillow/pillow-wheels#90 is now merged and Pillow-5.2.0-cp37-cp37m-*.whl are in the Pillow Wheel Builder container.

http://a365fff413fe338398b6-1c8a9b3114517dc5fe17b7c3f8c63a43.r19.cf2.rackcdn.com/

I can upload them to PyPI tomorrow, unless someone else can do it before then.

Done, I think: #3074 (comment)

👍 Confirmed wheel available for 3.7 on macOS:

I've made a new issue to track the Windows test fail: #3228.

The checklist was very useful and had everything I needed. Here's a PR to update a few little things: #3229.

I think we're all done here, closing this issue, thanks everyone!

@radarhere

Great!

@python-pillow/pillow-team While we are at it, let's cue up another Maintainer. @radarhere any interest in driving next release?

Okay, sure, it can be my turn to do it.

@radarhere

@radarhere Are you @radarhere on PyPI?

@aclark4life

@aclark4life yes. I imagine I'll also need to be part of the pillow-wheels team here.

@radarhere

@radarhere Done and done, thanks.
