# Deprecation: #90964 - LanguageService functionality and internal properties

See [forge#90964](https://forge.typo3.org/issues/90964)

## Description

LanguageService - also known as `$GLOBALS[LANG]` within TYPO3 Core
is used to fetch a label string from a XLF file and deliver the
translated value from that string.

Some functionality related to legacy functionality or internal logic has been marked as deprecated and changed visibility:

-   `LanguageService->LL_files_cache` \- is now protected instead of public
-   `LanguageService->LL_labels_cache` \- is now protected instead of public
-   `LanguageService->getLabelsWithPrefix()` \- is deprecated as it is not needed
-   `LanguageService->getLLL()` \- is now protected instead of public
-   `LanguageService->debugLL()` \- is now protected instead of public

The method `LanguageService->loadSingleTableDescription()` is marked as internal now.

## Impact

Calling any of the methods or properties listed above will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

TYPO3 installations with extensions of custom logic using the internals of specifics of the `LanguageService` class.

## Migration

Use the Public API of the `LanguageService` \- namely `sL()` and `getLL()` directly.
