This will obviously be a bigger change than dropping other minor versions, so it's a good idea to start thinking about how to proceed and to communicate that sooner rather than later.

Looking at Pillow's PyPI stats, Python 3 accounts for 60% of downloads and is increasing.

Here's the pip installs for pillow from PyPI for January 2019:

category	percent	downloads
3	59.17%	3,138,659
2	40.03%	2,123,506
null	0.79%	42,021
Total		5,304,186

Pip has started warning that Python 2 support will be dropped in a future version and a number of other projects have pledged to drop it no later than 2020. The latest Django 2.x has already dropped it and:

Django 1.11 is the last version to support Python 2.7. Support for Python 2.7 and Django 1.11 ends in 2020.

What should Pillow do?
