* **libimagequant** provides improved color quantization
* Pillow has been tested with libimagequant **2.6-2.17.0**
* Pillow has been tested with libimagequant **2.6-4.0**
* Libimagequant is licensed GPLv3, which is more restrictive than
the Pillow license, therefore we will not be distributing binaries
with libimagequant support enabled.
