.. _change in PyPI policy: https://blog.pypi.org/posts/2023-05-23-removing-pgp/

Deprecated
----------

* 11412: Emit warnings on using a deprecated Python-specific index entry type
(namely, ``module``, ``keyword``, ``operator``, ``object``, ``exception``,
``statement``, and ``builtin``) in the :rst:dir:`index` directive, and
set the removal version to Sphinx 9. Patch by Adam Turner.

Features added
--------------

* 11415: Add a checksum to JavaScript and CSS asset URIs included within
generated HTML, using the CRC32 algorithm.
* :meth:`~sphinx.application.Sphinx.require_sphinx` now allows the version
requirement to be specified as ``(major, minor)``.
* 11011: Allow configuring a line-length limit for object signatures, via
:confval:`maximum_signature_line_length` and the domain-specific variants.
If the length of the signature (in characters) is greater than the configured
limit, each parameter in the signature will be split to its own logical line.
This behaviour may also be controlled by options on object description

PEP 696 (default type parameters).  Multi-line support (11011) is enabled
for type parameters list and can be locally controlled on object description
directives, e.g., :rst:dir:`py:function:single-line-type-parameter-list`.
Patch by Bénédikt Tran.
* 11484: linkcheck: Allow HTML anchors to be ignored on a per-URL basis
via :confval:`linkcheck_anchors_ignore_for_url` while
still checking the validity of the page itself.
Patch by Bénédikt Tran
* 1246: Add translation progress statistics and inspection support,
via a new substitution (``|translation progress|``) and a new
configuration variable (:confval:`translation_progress_classes`).

a document, and the remaining translated and untranslated elements.

----------

* Restored the ``footnote-reference`` class that has been removed in
the latest (unreleased) version of Docutils.

in ``BuildEnvironment.get_outdated_files``.
* 11437: Top-level headings starting with a reStructuredText role
now render properly when :confval:`rst_prolog` is set.
Previously, a file starting with the below would have
improperly rendered due to where the prologue text
was inserted into the document.

Incompatible changes
--------------------

* 7405: Removed the jQuery and underscore.js JavaScript frameworks.

These frameworks are no longer be automatically injected into themes from
Sphinx 6.0. If you develop a theme or extension that uses the
``jQuery``, ``$``, or ``$u`` global objects, you need to update your
JavaScript to modern standards, or use the mitigation below.

The first option is to use the sphinxcontrib.jquery_ extension, which has been
developed by the Sphinx team and contributors. To use this, add
``sphinxcontrib.jquery`` to the ``extensions`` list in ``conf.py``, or call
``app.setup_extension("sphinxcontrib.jquery")`` if you develop a Sphinx theme
or extension.

The second option is to manually ensure that the frameworks are present.
To re-add jQuery and underscore.js, you will need to copy ``jquery.js`` and
``underscore.js`` from `the Sphinx repository`_ to your ``static`` directory,
and add the following to your ``layout.html``:

.. code-block:: html+jinja

  {%- block scripts %}
      <script src="{{ pathto('_static/jquery.js', resource=True) }}"></script>
      <script src="{{ pathto('_static/underscore.js', resource=True) }}"></script>
      {{ super() }}
  {%- endblock %}

.. _sphinxcontrib.jquery: https://github.com/sphinx-contrib/jquery/

``pre_background-TeXcolor`` :ref:`additionalcss` for the former defaults
and how to re-enact them if desired.

Bugs fixed
----------

* 10984: LaTeX: Document :confval:`latex_additional_files` behavior for files
with ``.tex`` extension.
