 * **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.
