Dependencies

• #13000: Drop Python 3.10 support.

Incompatible changes

• #13044: Remove the internal and undocumented has_equations data from the MathDomain domain. The undocumented MathDomain.has_equations method now unconditionally returns True. These are replaced by the has_maths_elements key of the page context dict. Patch by Adam Turner.
• #13227: HTML output for sequences of keys in the kbd role no longer uses a <kbd class="kbd compound"> element to wrap the keys and separators, but places them directly in the relevant parent node. This means that CSS rulesets targeting kbd.compound or .kbd.compound will no longer have any effect. Patch by Adam Turner.

Deprecated

• #13037: Deprecate the SingleHTMLBuilder.fix_refuris method. Patch by James Addison.
• #13083, #13330: Un-deprecate sphinx.util.import_object. Patch by Matthias Geier.

Features added

• #13173: Add a new duplicate_declaration warning type, with duplicate_declaration.c and duplicate_declaration.cpp subtypes. Patch by Julien Lecomte and Adam Turner.
• #11824: linkcode: Allow extensions to add support for a domain by defining the keys that should be present.
