### Added - Options wrapping `\tl_if_blank:nTF` and `\tl_if_empty:nTF` (issue #179) - Option `IfBlankTF` - Option `IfBlankT` - Option `IfBlankF` - Option `IfEmptyTF` - Option `IfEmptyT` - Option `IfEmptyF` - Options to insert code at begin and end of floats (issue #172) - Option `before float` - Option `after float` - Option `before float app` - Option `before float pre` - Option `after float app` - Option `after float pre` - Library `skins`: overlap of lower part for `bicolor`, `tile`, and `beamer` made configurable (issue #166) by - Option `overlaplower` - `\tcboverlaplower` - Library `documentation`: package warning, if `imakeidx` is loaded after the library is loaded (issue #173) - Library `documentation`: gather index LaTeX macros and configure gathering (issue #174) - Option `doclang/commands` - Option `index gather colors` - Option `index gather commands` - Option `index gather counters` - Option `index gather environments` - Option `index gather keys` - Option `index gather lengths` - Option `index gather paths` - Option `index gather values` - Option `index gather all` - Option `index gather none` ### Changed - Required latex2e specified `\NeedsTeXFormat{LaTeX2e}[2020/10/01]` (issue #170) - Documentation: comment `default setting` for `every box on higher layers` (issue #168) - Documentation: hyperlinking keys and commands where not already done inside the listings section (part of issue #175) - All contents of library `xparse` are moved to the `tcolorbox` main package and to libraries `listings` and `fitting` respectively. `xparse` now only loads the package `xparse` (issue #180) - Internal implementation of all `\new*` commands, e.g. `\newtcolorbox` changed. Note that a missing backlash for `tcbox`-like commands e.g. `\newtcbox{mybox}` instead of `\newtcbox{\mybox}` is no longer tolerated. ### Fixed - With `parbox=false`, `before skip` was ignored in inner box (issue #171)

tcolorbox – Coloured boxes, for LaTeX examples and theorems, etc

This package provides an environment for coloured and framed text boxes with a heading line. Optionally, such a box may be split in an upper and a lower part; thus the package may be used for the setting of examples where one part of the box displays the source code and the other part shows the output. Another common use case is the setting of theorems. The package supports saving and reuse of source code and text parts.

The package depends on the pgf, verbatim, environ, and etoolbox packages.
