History
=======

2003/12/15 v1.06
* New feature: extended color expressions, allowing for cascaded mix
  operations, e.g. \color{red!30!green!40!blue}.
* Documentation: new section on color expressions.
* Bugfix: color series stepping did not work correctly within
  non-displaying commands like \extractcolorspec{foo!!+}
  (this bug was introduced in v1.05).
* Renamed commands: \ukfileversion and similar internal constants
  renamed to \XCfileversion etc.
* Removed commands: \ifXCpst and \ifXCtable made obsolete by a simple
  trick.

2003/11/21 v1.05
* Bugfixes:
    - Package option `hideerrors' should now work as expected.
    - Usage of `.' in the first color expression in a document caused
      an error due to incorrect initialisation.
* Code re-organisation: \extractcolorspec now uses \XC@splitcolor,
  making \XC@extract obsolete.

2003/11/09 v1.04
