The fork author’s goal is to foster and support active development of PIL through:

Why a fork?¶
PIL is not setuptools compatible. Please see this Image-SIG post for a more detailed explanation. Also, PIL’s current bi-yearly (or greater) release schedule is too infrequent to accommodate the large number and frequency of issues reported.
What about PIL?¶
Prior to Pillow 2.0.0, very few image code changes were made. Pillow 2.0.0 added Python 3 support and includes many bug fixes from many contributors.
As more time passes since the last PIL release, the likelihood of a new PIL release decreases. However, we’ve yet to hear an official “PIL is dead” announcement. So if you still want to support PIL, please report issues here first, then open corresponding Pillow tickets here.
Please provide a link to the first ticket so we can track the issue(s) upstream.
