CTAN update: tcolorbox

[CTAN Announcements]

Thomas F. Sturm submitted an update to the

                   tcolorbox

package.

Version:  6.0.4 2023-06-19
License:  lppl1.3

Summary description:  Coloured boxes, for LaTeX examples and theorems, etc

Announcement text:
----------------------------------------------------------------------

 ### Changed
 - Documentation title page background made non-selectable
   (PDF reader dependent!) (issue #225)
 - Implementation for zref-clever support improved (issue #230)
 - Wrong option name inside the documentation for `halign title`
   (issue #231)
 - `extrude left by` and `extrude right by` now also change spacing
   for title and lower part (issue #228)
 - `\newtcbox` and similar macros needed curly braces to protect
   square brackets for key values.  The implementation is adapted
   to avoid such a need at several places (issue #229)

 ### Fixed
 - The last version war inconsistently numbered 6.0.2 and/or 6.0.3
   (issue #224)
 - New LaTeX versions (from 2023-06-01) remove `\parskip` at top
   of `minipage`.  Therefore, `parbox=false` has to be adapted
   (issue #232)
