Breaking: #98239 - Removed "afterBuildingFinished" hook 

See forge#98239

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 

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

Affected installations 

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

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 or AfterFormIsBuiltEvent to achieve the same functionality with the new event-based system.
