# Breaking: #98239 - Removed "afterBuildingFinished" hook {#breaking-98239-1758890437}

See [forge#98239](https://forge.typo3.org/issues/98239)

## Description {#description}

The hook `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['ext/form']['afterBuildingFinished']`
has been removed in favor of the more powerful PSR-14 events
`\TYPO3\CMS\Form\Event\BeforeRenderableIsAddedToFormEvent` and
`\TYPO3\CMS\Form\Event\AfterFormIsBuiltEvent`.

## Impact {#impact}

Any hook implementation registered under this identifier will no longer be
executed in TYPO3 v14.0 and later.

## Affected installations {#affected-installations}

TYPO3 installations with custom extensions that implement this hook are
affected. The extension scanner reports such usages as a weak match.

## Migration {#migration}

The hook has been removed without a deprecation phase to allow extensions to
remain compatible with both TYPO3 v13 (using the hook) and v14+ (using the new
events). Implementing the PSR-14 events provides the same or greater control
over form rendering.

Use the [BeforeRenderableIsAddedToFormEvent](https://docs.typo3.org/permalink/changelog:feature-107518-1758539757) or
[AfterFormIsBuiltEvent](https://docs.typo3.org/permalink/changelog:feature-98239-1758890522) to achieve the same
functionality with the new event-based system.
