On Sat, 26 Nov 2005 Uwe Kern submitted an update to the
  xcolor
package.
This package pProvides easy driver-independent access to several kinds of
color tints, shades, tones, and mixes of arbitrary colors.  It allows a
user to select a document-wide target color model and offers complete
tools for conversion between eight color models.  Additionally, there is a
command for alternating row colors plus repeated non-aligned material
(like horizontal lines) in tables.  Colors can be mixed like
color{red!30!green!40!blue}.

----------------------------------------------------------------------
2005/11/25 v2.08
 * New features:
     - more flexibility for fcolorbox arguments, e.g.,
       fcolorbox[gray]{0.5}[wave]{580}{test};
     - oxframe returns a frame of given dimensions;
     - new implementation of f(rame)box and fcolorbox as an extension
       of bug report latex/3655 to reduce pixel positioning errors in
       output devices;
     - `kernelfbox' option for those who prefer the previous f(rame)box
       approach;
     - experimental `xcdraw' option uses PostScript commands to draw
       frames and color boxes in case of `dvips'.
 * Bugfixes:
     - insufficient expression type detection within colorlet;
     - wrong calculation in the unit interval reduction for negative
       integers (affecting color series and extended color expressions).
