Deprecation: #93944 - File Tree as iframe migrated to SVG-based tree

See forge#93944

Description

When registered backend modules have the legacy-tree navigation frame file_navframe set via the module configuration navigationFrameModule, the modules are now using the new SVG-based Folder tree view as component (non-iFrame).

Impact

Modules still registering the old file_navframe option via Module Configuration navigationFrameModule will automatically be migrated to the new Component, and a PHP E_USER_DEPRECATED error will be triggered.

Affected Installations

TYPO3 installations with custom extensions having backend modules using the filelist navigation frame (folder-based tree).

Modules that use the implicit main module configuration and are located directly within the "File" module are not affected.

Migration

Change the affected code in your ext_tables.php:

'navigationFrameModule' => 'file_navframe'

to

'navigationComponentId' => 'TYPO3/CMS/Backend/Tree/FileStorageTreeContainer'
