+* plugins/Sphinx: Sphinx 7.3.0 has introduced a
+  `new configuration format <https://github.com/sphinx-doc/sphinx/pull/12265>`__ for themes.
+  This breaks the way we parse the theme configuration.
+  For this bugfix release we pin the Sphinx dependency to :code:`<7.3.0` to work around this problem.
