The implementation is adapted to avoid such a need at several places (issue #229) ### Fixed - The last version was 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) ## [6.0.2/6.0.3] - 2023-03-17 ### 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) ## [6.0.1] - 2023-02-12 ### Fixed - Typo in CHANGES.md (issue #211) - Regression bug: `\NewTCBInputListing` without initialization options produces an error (issue #212) ## [6.0.0] - 2023-02-10 ### Added - Generalized text alignment options (issue #184) - Option `halign code` - Option `halign upper code` - Option `halign lower code` - Option `halign title code` - New Options: - Option `before title*` (equals `before title` until 5.1.1) - Option `after title*` (equals `after title` until 5.1.1) - New option for verbatim output and listings: - Option `verbatim ignore indention at end` - Option `short title` (part of issue #186) - Support for zref / zref-titleref / zref-clever (issue #206) - Option `label is label` - Option `label is zlabel` - Library `theorems`: New theorem generation macros. Generated theorems support an optional short title now (part of issue #186): - `\NewTcbTheorem` - `\RenewTcbTheorem` - `\ProvideTcbTheorem` - `\DeclareTcbTheorem` - Library `skins`: Default values added to the options - `watermark zoom` - `watermark shrink` - `watermark overzoom` - `watermark stretch` ### Changed - Possible visible change: previous hacks of current color handling are removed (issue #204) and color is now inserted at begin of all internal `\box`es. This inserts a whatsit and can give additional space at begin of a box which starts with an `itemize` or a similar environment. If necessary, such a space may be removed by a manual `\vspace{-\parsep}`, see issue #123 Note: lualatex with package luacolor removes all spacing problems - While producing new types of tcolorbox environment by `\newtcolorbox` leading and trailing spaces are now removed from the environment name - `before title` appends `\ignorespaces` now - `after title` prepends `\unskip` now - `tcbverbatimwrite` sets `verbatim ignore indention at end` to remove spaces from indention of the end of environment - `nameref` also sets zref-titleref reference - `label type` is used for cleveref and zref-clever - The 'TikZ Image and Picture Fill Extensions' are extracted from library `skins` into an `tcolorbox` indendent TikZ library `tikzfill.image` and made part of a new package `tikzfill`. Also, the respective documentation is moved into this new package (issue #185) - Library `skins`: The implementation of all watermark options is changed and adapted to `tikzfill`. `clip watermark=false` has now some restrictions (see documentation) - Library `skins`: `\tcbincludegraphics` implementation changed to LaTeX3 code (should be more robust; inspired by issue #209) - Temporary `\tcbcounter` in `\newtcolorbox[auto counter]` undefined/restored after usage (issue #203) - Color setting example of subtitle inside `subtitle style` (issue #189) - Documentation: - The documentation orders now `\New...`, `\Renew...`, `\Provide...`, `\Declare...`. Previously, `\Declare...` was often used first. - `NewTotalTColorBox` cannot be used with `saveto` or `savelowerto` (issue #205) - Replacing `\tikzname` by TikZ in a comment line (issue #207) - `list entry`, `list text`, `add to list` moved from *Counters, Labels, and References* to *Lists of tcolorboxes* for clarification (issue #194) ### Removed - Code `\tcb@undo@before` which tried to undo vertical space for a breakable box which does not fit partially on the current page but needs to go to the following page. This code did not achieve the goal and was error-prone (issue #200, hint inside issue #183) ### Fixed - `\Provide...` commands and environments process initialization options (issue #187) - Default initialization options were not issued, if `\newtcolorbox` was used without options (issue #194) - Typo in `\RenewTCBox` and `\RenewTotalTCBox` caused errors (issue #201) - Typo in README.md (issue #196) ## [5.1.1] - 2022-06-24 ### Changed - Some documentation improvements - Library `xparse` removed from settings `many` and `most` - Slight implemenation change for `\newtcbtheorem` and `\renewtcbtheorem` ### Fixed - Regression bug introduced with v5.0.0 2021-12-16 (issue #182) Instead of `beforeafter skip balanced`, `autoparskip` was set as default, restoring the situation before v4.40 (with some inconsistencies) ## [5.1.0] - 2022-06-22 ### 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) ## [5.0.2] - 2022-01-07 ### Changed - Library `minted`: Temporary patch `\tcbTemporaryPatchMintedFancyvrb` removed because of update for package `minted` (2021/12/24).
