• \TYPO3\CMS\Lang\View\Language\UpdateLanguageJson
• \TYPO3\CMS\Lang\View\Language\UpdateTranslationJson

Impact

Using one of the mentioned classes will throw a fatal PHP error.

Affected Installations

It is unlikely extensions used the mentioned classes, the extension scanner will find usages. The only well-known usage of one of this classes is the signal/slot to override the base download url of language packs per extension and the registration did not change and should still be done like this:

/** @var \TYPO3\CMS\Extbase\SignalSlot\Dispatcher $signalSlotDispatcher */
$signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\TYPO3\CMS\Extbase\SignalSlot\Dispatcher::class);

$signalSlotDispatcher->connect(
    'TYPO3\\CMS\\Lang\\Service\\TranslationService',
    'postProcessMirrorUrl',
    \Company\Extension\Slots\CustomMirror::class,
    'postProcessMirrorUrl'
);
