Thomas F. Sturm submitted an update to the
tcolorbox
package.
Version number: 4.42 2020-10-09 License type: lppl1.3
Summary description: Coloured boxes, for LaTeX examples and theorems, etc
Announcement text: ----------------------------------------------------------------------
- due to several problems with the color algorithm introduced with version 4.32, essentially reversion to the proven pre 4.32 method. * support of luacolor persists (since 4.32) * color stacks (by pdfcol) are not mandatory any more, but are optional now with 'use color stack'. Note that effects of whatsits on the vertical space have to be expected.
