Breaking: #84148 - RequireJS module for language handling removed

See forge#84148


Since the removal of ExtJS, the JavaScript files that handled the localization of labels in backend modules became obsolete and have been removed.


Depending on the RequireJS module TYPO3/CMS/Lang/Lang will result in 404 errors, as the module has been removed.

Affected Installations

Every 3rd party extension depending on TYPO3/CMS/Lang/Lang is affected.


Remove the module from the affected RequireJS modules. The labels are now prepared by the PageRenderer and passed to TYPO3.lang without the need of additional JavaScript.
