Breaking: #69795 - Unused DTM Tabmenu code removed¶

See forge#69795

Description¶

All DynTabMenu JavaScript and CSS code which was previously used to render Tab Menus in the TYPO3 Backend has been removed without substitution.

Impact¶

All logic that requires EXT:backend/Resources/Public/JavaScript/tabmenu.js directly and/or use the JavaScript code of DTM_activate() or DTM_toggle() directly have been removed.

Affected Installations¶

TYPO3 Installations with custom extensions that use the logic mentioned above.

Migration¶

Use ModuleTemplate::getDynamicTabMenu() directly to use the Bootstrap-based API shipped with the TYPO3 Core.
