Breaking: #82378 - Remove namespaced jQuery

See forge#82378


The possibility to jail jQuery into a namespace has been removed. This affects custom namespaces and TYPO3.jQuery as well.

The class constants TYPO3\CMS\Core\Page\PageRenderer::JQUERY_NAMESPACE_DEFAULT and TYPO3\CMS\Core\Page\PageRenderer::JQUERY_NAMESPACE_DEFAULT_NOCONFLICT have been removed without substitution, any usage will be detected by the Extension Scanner.


Namespaces will be ignored and automatically fall back to noConflict behavior.

Calling TYPO3.jQuery.* will result in a TypeError.

Affected Installations

All installations using a custom namespace, PageRenderer::JQUERY_NAMESPACE_DEFAULT PageRenderer::JQUERY_NAMESPACE_DEFAULT or relying on TYPO3.jQuery are affected.


Remove $namespace argument in PageRenderer->loadJquery() and either use window.$ or migrate to RequireJS.
