* The directive option ``:noindex:`` was renamed to ``:no-index:``.
* The directive option ``:noindexentry:`` was renamed to ``:no-index-entry:``.
* The directive option ``:nocontentsentry:`` was renamed to ``:no-contents-entry:``.
The previous names are retained as aliases, but will be deprecated
and removed in a future version of Sphinx (9.0 or later).
Named auto numbered footnote (ex. ``[#named]``) that is referred
multiple times was rendered to a question mark.
This calls `\sphinxstepexplicit` for every footnote node that is
referred multiple times.
Allow code-blocks in footnotes for LaTeX PDF output.
This is done via using a ``footnote environment``, provided by LaTeX
package footnotehyper which replaces old problematic package footnote.
No need to ship a custom tabulary anymore.
The footnote markers are silently removed from the table of contents and
do not end in the PDF bookmarks (the old code in ``sphinx.sty`` copying
``footmisc.sty`` was not satisfactory and has been deleted and replaced
by use of better ``\sphinxfootnotemark``.) Footnotes can be used also in
captions of literal blocks.
