Release Notes: This release improves support for more modern C++ compilers, improves performance, and adds new commandline options.
Release Notes: The dithering algorithms have been completely rewritten, offering a very sophisticated set of parameters to the quantization and dithering of animations and static images. Support was also added for formulaic image transformations using a high performance function parser library.
Release Notes: This release adds new pixel methods and adds an entirely new class of features aiming to compensate for areas in source pictures marked unusable ("masked"). The color quantization (palettization) and dithering features were also significantly improved.
