# Deprecation: #93038 - ReferenceIndex runtime cache

See [forge#93038](https://forge.typo3.org/issues/93038)

## Description

Two methods of class `ReferenceIndex` have been marked as deprecated:

-   `ReferenceIndex->enableRuntimeCache()`
-   `ReferenceIndex->disableRuntimeCache()`

## Impact

Calling these methods will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

Instances with extensions calling above methods are affected. The extension
scanner locates candidates.

## Migration

The method calls can be dropped, cache handling is done internally.
