Deprecation: #94094 - navigationFrameModule in Module Registration

See Issue #94094

Description

TYPO3 allowed for each module to include an iframe for the navigation area with the option navigationFrameModule and navigationFrameModuleParameters. Since TYPO3 4.5 it was possible to also use a JavaScript component instead via navigationComponentId.

TYPO3 v11 allows to use Web Components for the navigationComponentId option, and all core-based navigation components have been migrated to Lit-based Web Components.

With this technology, TYPO3 does not need to handle iframes for the navigation area anymore, which is why the feature, together with the option navigationFrameModule has been marked as deprecated.

Impact

TYPO3 installations with third-party extensions registering custom navigation iframes will trigger a deprecation log entry.

Affected Installations

TYPO3 installations with third-party extensions shipping modules with a custom navigation iframe.

Migration

Migration should be done to use Web Components, as this is much faster and allows for better operability due to less usages of iframes.
