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 directives, for example :rst:dir:py:function:single-line-parameter-list.
