    Release Notes: This release adds a min/max quality option (the number of colors is automatically adjusted for the desired quality level), a switch of option parsing to getopt_long (a syntax such as -s1 and --ext=ext is supported), significantly-improved performance thanks to custom partial sorting, an optional Cocoa (Mac OS X) image reader for color profile support, 20% reduced memory usage, and remapping improvements for very low numbers of colors.

      Release Notes: This release adds a new, accurate RGBA color similarity algorithm, a change of the optional SSE3 code to SSE2 which is always enabled on x86-64, optional OpenMP-based parallelization of remapping, and a change of long options to use double hyphens (-force to --force).

        Release Notes: This release changes the dithering algorithm to add noise only on flat areas of the image, makes remapping adapt to contrast and noise in the image, increases the quality of post-processing palettes, and improves speed.

              Release Notes: Version 1.0 is primarily confirmation that 0.95 was more than stable enough to have been called 1.0 itself. The Unix makefile has also been cleaned up, and the Linux/glibc binary was recompiled against zlib 1.1.4 for karmic maximization.
