# Breaking: #97187 - Removed hook for modifying link explanation {#breaking-97187}

See [forge#97187](https://forge.typo3.org/issues/97187)

## Description {#description}

The hook `$GLOBALS['TYPO3_CONF_VARS']['SYS']['formEngine']['linkHandler']`
has been removed in favor of a new PSR-14 event `\TYPO3\CMS\Backend\Form\Event\ModifyLinkExplanationEvent`.

## Impact {#impact}

Any hook implementation registered is not executed anymore in
TYPO3 v12.0+. The extension scanner will report possible usages.

## Affected Installations {#affected-installations}

All TYPO3 installations using this hook in custom extension code.

## Migration {#migration}

The hook is removed without deprecation in order to allow extensions
to work with TYPO3 v11 (using the hook) and v12+ (using the new event).

Use the [PSR-14 event](https://docs.typo3.org/permalink/changelog:feature-97187)
as an improved replacement.
