Uwe Kern asked me to add the list of changes to the xcolor 2.0 accouncement of a few minutes ago.
---------------------------------------------------------------------- 2004/07/04 v2.00 * New features: - extended functionality for color expressions: mix colors like a painter; - support for color blending: specify color mix expressions that are being blended with every displayed color; - xglobal command for selective control of globality for color definitions, blends, and masks; - multiple step operations (e.g. color{foo!!+++}) and access to individual members (e.g. color{foo!![7]}) in color series; - providecolor command to define only non-existent colors; - definecolorset and providecolorset commands to facilitate the construction of color sets with common underlying color model; - additional 147 predefined color names according to SVG 1.1 specification; - `xpdfborder' key for setting the width of hyperlink borders in a more driver-independent way if `dvips' is used. * Changes: - `color' package now completely integrated within `xcolor'; - `override', `usenames', `nodvipsnames' options and xdefinecolor command no longer needed; - `dvips' and `dvipsnames' options now independent of each other; - racingcolors's behaviour changed to make it more versatile and reduce log file size in standard cases; - divide's syntax made more flexible (divide by numbers and/or dimensions); - code restructured, some internal commands renamed; - documentation rearranged and enhanced. * Bugfixes: - definecolor{foo}{named}{bar} did not work (error introduced in v1.11); - more robust behaviour of conditionals within `pstricks' key-values. ----------------------------------------------------------------------
