分支作者的愿景是通过以下途径活跃 PIL 的开发：
和PIL一样，Pillow 使用 MIT-like PIL Software License

PIL 不兼容setuptools，请阅读 this Image-SIG post 获取更多解释。而且 PIL 计划一年更新两次太慢了不能解决大量issues报告。
注解
Pillow 2.0.0 之前，Pillow相对于 PIL 更改很少。Pillow 2.0.0 开始增加 Python 3 的支持进行了很多 Bug 修正。
距离上次 PIL 发布更新的时间越久，PIL 更新的可能性越小。然而，PIL官方还没有正式宣布PIL死亡，如果你还想支持 PIL 可以先报告给 PIL： report issues here first, 然后报告给 Pillow： open the corresponding Pillow tickets here.
报告给 Pillow 的时候请带上 PIL 的链接方便我们跟踪。
