package.

Version: 6.0.3 2023-03-17

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

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

### Added
- Usage of `\tcblower` where not applicable gives a more helpful error message (issue #215)
- Usage of `capture=fitbox` for `\tcbox` gives an error message (issue #217)
- Library documentation:
- Macro `\sarg` (issue #193)

### Changed
- Documentation:
- List of initialization option macros enlarged (issue #213)
- Removed `xparse` references (issue #214)
- Typo correction (issue #216, issue #219)
- Library `skins`:
- `\tcbhypernode` made compatible for xelatex (issue #221)

### Fixed
- `parbox=false` accumulated negative `\parskip` values, if called several times
or used with `attach title to upper` (issue #222)
- Library `breakable`:
- Reverting to `\color{.}` hack to avoid color bleeding after the box
- `Discard zero height first box part` problem hopefully solved (issue #218)
