Release 6.0.0 (released Dec 29, 2022)

Dependencies

• #10468: Drop Python 3.6 support
• #10470: Drop Python 3.7, Docutils 0.14, Docutils 0.15, Docutils 0.16, and Docutils 0.17 support. Patch by Adam Turner

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 %} {{ super() }} {%- endblock %}

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

  Patch by Adam Turner.

• #10471, #10565: Removed deprecated APIs scheduled for removal in Sphinx 6.0. See :ref:dev-deprecated-apis for details. Patch by Adam Turner.

• #10901: C Domain: Remove support for parsing pre-v3 style type directives and roles. Also remove associated configuration variables c_allow_pre_v3 and c_warn_on_allowed_pre_v3. Patch by Adam Turner.

[ctb]

This PR was occasioned by sphinx releasing v6.0.0.

When I test this in a separate environment with sphinx==6, the documentation looks good. However, myst-parser (latest: v0.18.1) does not yet (formally) support sphinx >= 6 so presumably that will limit actual installs of sphinx 6.

[ctb]

(which goes to say: I will merge, but we will still be on sphinx 5.x until myst-parser updates its requirements)
