# Breaking: #84148 - RequireJS module for language handling removed {#breaking-84148}

See [forge#84148](https://forge.typo3.org/issues/84148)

## Description {#description}

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

## Impact {#impact}

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

## Affected Installations {#affected-installations}

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

## Migration {#migration}

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.
