2016/05/11 v2.12
* New features:
- \nopagecolor command as introduced in `color' v1.1a
(example added to xcolor3.tex);
- `luatex' driver option (code provided by DPC) to fix
incompatibilities due to changes in new LuaTeX version.
* Bugfixes:
- possible name conflict by \XC@ifxcase call;
- incorrect internal \@hex@@Hex macro.
2007/01/21 v2.11
* New features:

colors.
* Bugfix:
- incorrect \XC@strip@comma call within `hyperref'-related options.
2006/11/28 v2.10
* New features:
- `fixinclude' option prevents dvips from explicitly resetting
current color to `black' before actually inserting an .eps file
via \color{red}\includegraphics{foo}.
* Changes:
- \colorbox and \fcolorbox made robust;
- obsolete package option `pst' removed;
- several changes to internal macros.
* Bugfixes:
- incorrect processing of cmyk-type current color `.'.
2005/12/21 v2.09
* New features:
- \definecolor and \color now accept space-separated color
specifications, e.g., \color[rgb]{1 .5 0};
- experimental `xcdraw' option extended to `pdftex' and `dvipdfm'
drivers.
* Changes:
- test file xcolor2.tex made compatible with recent changes in
`pstricks';
- test file xcolor3.tex extended;
- driver test file xcolor4.tex extended to demonstrate the different
frame drawing approaches;
- more efficient implementation of driver-specific code.
2005/11/25 v2.08

\fcolorbox[gray]{0.5}[wave]{580}{test};
- \boxframe 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).
2005/11/12 v2.07
* New features:
- color model `Hsb' allows to specify hue in degrees;
- color model `tHsb' (`tuned Hsb') for user-defined hue
configuration on color wheels;
- easy generation of color harmonies derived from `Hsb' or `tHsb'
color wheels, e.g., \color{red>wheel,1,12} yields an `analogous'
color to `red' on a 12-spoke wheel;
- additional 317 predefined color names according to rgb.txt, which
is part of Unix/X11 distributions;
- `svgnames' option extended by 4 colors taken from rgb.txt;

* Bugfixes:
- wrong calculation of color series components in some cases of
negative step parameters.
2005/10/15 v2.06
* New features:
- color model `wave' for (approximate) visualisation of light
wavelengths, still somewhat experimental;
- pseudo-model `ps' for colors defined by literal PostScript code
in conjunction with `pstricks and `dvips'; an illustrative
example for a gamma-correction approach is given in xcolor2.tex;
- \substitutecolormodel command for replacement of missing or
faulty driver-specific color models;
- improved detection and handling of driver-specific color models;
- `dvipdfmx' and `xetex' options to support these drivers;
- generic driver test file xcolor4.tex.
* Changes:
- \XC@strip@comma doesn't generate a trailing space anymore, which
improves also the output of the `testcolors' environment.
2005/09/30 v2.05
* New features:
- `testcolors' environment helps to test colors in different models,
showing both the visual result and the model-specific parameters;
- \extractcolorspecs puts model/color specification into two
separate commands, as opposed to \extractcolorspec;
- color names `pink' and `olive' added to the set of predefined
colors.
* Bugfixes:
- \definecolor{foo}{named}{bar} did not work in v2.04.
2005/09/23 v2.04
* New features:
- preparation for usage of additional - driver-provided - color
models;
- `pstricks' users may now specify explicit color parameters within
\psset and related commands, e.g., \psset{linecolor=[rgb]{1,0,0}};
an illustrative example is given in xcolor2.tex.
* Changes:
- color model names sanitized (i.e., turned to catcode 12)
throughout the package;
- \@namelet command deprecated because of name clash with
`memoir' - please use \XC@let@cc instead
(more \XC@let@.. commands are available as well);
- simplified color conversion code by using the new \XC@ifxcase
command;
- some minor changes to internal macros.
2005/06/06 v2.03
* New features:
- `fixpdftex' option loads `pdfcolmk' package in order to improve
pdfTeX's color behaviour during page breaks.
* Changes:
- some minor changes to internal macros.
* Bugfixes:
- due to an incorrect \if statement within \XC@info, \colorlet
caused trouble whenever its second argument started with two
identical letters, e.g., \colorlet{rab}{oof};
- argument processing of \XC@getcolor caused incompatibility with
`msc' package;
- `prologue' option caused incompatibility with `preview' package.
2005/03/24 v2.02
* New features:
- \aftergroupedef command to reproduce \aftergroupdef's behaviour
prior to v2.01;
- xcolor's homepage www.ukern.de/tex/xcolor.html now provides also
a ready-to-run TDS-compliant archive containing all required
files.
* Changes:
- \rowcolors and friends are solely enabled by the `table' option;
- \@ifxempty changed back to more robust variant of v2.00.
* Bugfixes:
- \psset{linecolor=\ifcase\foo red\or green\or blue\fi} did not work
with `pstricks' (error introduced in v2.01).
2005/03/15 v2.01
* New features:
- `prologue' option for comprehensive `named' color support in
conjunction with `dvips': on-the-fly generation of PostScript
prologue files with all color definitions, ready for dvips
inclusion and/or post-processing with device-specific parameters
(e.g., spot colors);
- dvips prologue file xcolor.pro to support additional `named'
colors;
- \colorlet may now also be used to create named colors from
arbitrary color expressions;
- enhanced color definition syntax to allow for target-model
specific color parameters, e.g.,
\definecolor{red}{rgb/cmyk}{1,0,0/0,1,1,0}, facilitating the
usage of tailor-made colors both for displays and printers;
- `deferred definition' of colors: \preparecolor and
\definecolors enable decoupling of color specification and control
sequence generation, especially useful (= memory saving) for large
lists of colors, of which only a few names are actually used;
- `dvipsnames*' and `svgnames*' options to support deferred
definition.
* Changes:
- higher accuracy: most complement calculations are now exact for
all 5-digit decimals;
- \rangeRGB and similar variables may now be changed at any point
in a document;
- \aftergroupdef now performs only a first-level expansion of its
code argument;
- \XCfileversion and similar internal constants removed from .sty
and .def files;
- improved memory management (reduced generation of `multiletter
control sequences' by \@ifundefined tests);
- several internal macros improved and/or renamed.
* Bugfixes:
- \XC@getcolor could cause unwanted spaces when \psset was used
inside |pspicture| environments (`pstricks');
- arithmetic overflow could happen when too many decimal digits
were used within color parameters, e.g., as a result of `fp'
calculations.
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;

global or local;
- option `hyperref' provides color expression support for the
border colors of hyperlinks, e.g.,
\hypersetup{xurlbordercolor=red!50!yellow};
- internal hooks \XC@bcolor, \XC@mcolor, and \XC@ecolor for
additional code that has to be executed immediately before/after
the current color is being displayed.
* Changes:
- \XC@logcolor renamed to \XC@display, which is now the core color
display command;
- improved interface to `pstricks'.
2004/03/27 v1.10
* New features:
- support for `named' model;
- support for `dvips' colors
(may now be used within color expressions);
- internal representation of `ordinary' and `named' colors merged
into unified data structure;
- allow multiple `-' signs at the beginning of color expressions.
* Bugfixes:
- commands like \color[named]{foo} caused errors when color masking
or target model conversion were active;
