Announcement text:
----------------------------------------------------------------------
### Added
 - Options wrapping `	l_if_blank:nTF` and `	l_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`
     - `	cboverlaplower`
 - 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 `
ew*` commands, e.g. `
ewtcolorbox` changed.
     Note that a missing backlash for `tcbox`-like commands
     e.g. `
ewtcbox{mybox}` instead of `
ewtcbox{mybox}` is no longer tolerated.
### Fixed
 - With `parbox=false`, `before skip` was ignored in inner box (issue #171)
