# Deprecation: #95275 - RelationHandler->remapMM()

See [forge#95275](https://forge.typo3.org/issues/95275)

## Description

Method `TYPO3\CMS\Core\Database\RelationHandler->remapMM()` has been
marked as deprecated and will be removed with TYPO3 v12.

## Impact

Calling above method will trigger a PHP `E_USER_DEPRECATED` error.

## Affected installations

It is highly unlikely instances are affected: The method handles a detail
related to workspaces publishing and is of little use in third party extensions.
The extension scanner will find usages as weak match.

## Migration

No direct substitution available, the method has been integrated into
`\TYPO3\CMS\Core\DataHandling\DataHandler`.
