\=====================================

## Dependencies

- [#&#8203;12555](https://togithub.com/sphinx-doc/sphinx/issues/12555):
Drop Docutils 0.18.1 and Docutils 0.19 support.
    Patch by Adam Turner.
- LaTeX: the `xcolor` package is now required (but is for example part
of
    Ubuntu `texlive-latex-recommended` which has always been required).
- LaTeX: the `fontawesome5` LaTeX package is needed for the default
choices
of icons now used in admonition titles in PDF output; but if unavailable
the
    PDF build will simply silently omit rendering such icons.  Check the
documentation of the `iconpackage` key of :ref:`'sphinxsetup'
<latexsphinxsetup>` for more.

## Deprecated

- LaTeX: the `sphinxlightbox` environment is not used anymore, all types
    of admonitions use (by default) only `sphinxheavybox`.
