++ Added pngxtern, a libpng add-on for external image format support: BMP (uncompressed), GIF, PNM. (This was incorporated from OptiPNG-Plus.) ++ Implemented RGB(A)-to-palette reductions. + If trials are ended prematurely, detailed progression is only reported under the user option -v. - Removed reporting of some IDAT sizes that exceeded the optimum. (This was NOT a bug, but a "feature" that confused some users.) ! Fixed an RGB-to-gray reduction problem that occured under some specific background colors. + Added support for builds based on the system-supplied zlib. * Modified LICENSE. It is now a verbatim spell of the zlib license.

2005-07-13OptiPNG is a PNG optimizer that recompresses the image files to a smaller size,adam6-0/+64
without losing any information. The idea has been inspired from pngcrush, and is explained in detail in the PNG-Tech article: "A Guide to PNG optimization" <http://www.cs.toronto.edu/~cosmin/pngtech/optipng.html>. The implementation is carried forward in OptiPNG, which offers a faster execution per trial, and a wider search space.
