# Deprecation: #99717 - Deprecated "modifyBlindedConfigurationOptions" hook {#deprecation-99717-1674654675}

See [forge#99717](https://forge.typo3.org/issues/99717)

## Description {#description}

The hook `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Lowlevel\Controller\ConfigurationController']['modifyBlindedConfigurationOptions']`
has been deprecated in favor of the new PSR-14
`\TYPO3\CMS\Lowlevel\Event\ModifyBlindedConfigurationOptionsEvent`,
which acts as a direct replacement.

## Impact {#impact}

Using the hook will trigger a deprecation log entry and any hook
implementation registered will not be executed anymore in TYPO3 v13.

## Affected installations {#affected-installations}

All installations using the deprecated hook. The extension scanner
will report possible usages.

## Migration {#migration}

Use the [PSR-14 event](https://docs.typo3.org/permalink/changelog:feature-99717-1674654720) as a direct replacement.
