+Breaking: #82378 - Remove namespaced jQuery
+===========================================
+
+See :issue:`82378`
+
+Description
+===========
+
+The possibility to jail jQuery into a namespace has been removed. This affects custom namespaces and
+:js:`TYPO3.jQuery` as well.
+
+The class constants :php:`TYPO3\CMS\Core\Page\PageRenderer::JQUERY_NAMESPACE_DEFAULT` and
+:php:`TYPO3\CMS\Core\Page\PageRenderer::JQUERY_NAMESPACE_DEFAULT_NOCONFLICT` have been removed without
+substitution, any usage will be detected by the Extension Scanner.
+
+
+Impact
+======
+
+Namespaces will be ignored and automatically fall back to noConflict behavior.
+
+Calling :js:`TYPO3.jQuery.*` will result in a TypeError.
+
+
+Affected Installations
+======================
+
+All installations using a custom namespace, :php:`PageRenderer::JQUERY_NAMESPACE_DEFAULT`
+:php:`PageRenderer::JQUERY_NAMESPACE_DEFAULT` or relying on :js:`TYPO3.jQuery` are affected.
+
+
+Migration
+=========
+
+Remove :php:`$namespace` argument in :php:`PageRenderer->loadJquery()` and either use :js:`window.$` or migrate
+to RequireJS.
