Thomas F. Sturm submitted an update to the

tcolorbox

package.

Version: 6.3.0 2024-07-10 License: lppl1.3

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

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

### Added - Library `documentation`: - Option `page ref formatter` (issue #273) - First experimental partial tagging support: suppress tagging of drawing (issue #283) This works for lualatex only.

### Changed - The base package loads `tikz` now instead of `pgf`. All skins, including the `standard` family, use `tikzpicture` as internal environment now. - Boolean marker to detect if inside a `tcb@savebox` introduced (issue #262) - LaTeX usrguide cited for `NewDocumentCommand` and friends (issue #263) - Stricter checks on box names in ` ewtcbox` and friends (issue #264) - Checks on formatter like `index key formatter` enforced (issue #265) - Needed LaTeX version updated to 2023-11-01 - More meaningful error message in case of `DeclareTColorBox` with same auto counter (issue #276) - Library `theorems`: - Options `ams align`, `ams align*`, `ams gather`, and `ams gather*` are now shortcuts for the upper part only (issue #282) - Documentation for `ams align`, `ams align*`, `ams gather`, and `ams gather*` adapted, i.e. exclusion of lower parts documented (issue #282) - Technical information: The package documentation is now produced with lualatex instead of pdflatex

### Deprecated - The option `graphical environment` is useless now, since all environments are based on `tikzpicture` now.

### Removed - Documentation for the deprecated options `before example` and `after example` - Documentation for the deprecated option `graphical environment`

### Fixed - `@nobreakfalse` added to ` cb@parbox@false@settings` to avoid decreased space before list with `parbox=false` following a section heading (issue #270) - Documentation typos fixed (issue #279)
