========================================================
Breaking: #107518 - Removed "initializeFormElement" hook
========================================================

See :issue:`107518`

Description
===========

The hook
:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['ext/form']['initializeFormElement']`
has been removed in favor of the PSR-14 event
:php:`\TYPO3\CMS\Form\Event\BeforeRenderableIsAddedToFormEvent`.

Impact
======

Hook implementations registered under
`initializeFormElement` are no longer executed in TYPO3 v14.0 and later.

Affected installations
======================

TYPO3 installations with custom extensions using this hook are affected.
The extension scanner reports any usage as a weak match.

Migration
=========

The hook was removed without a deprecation phase to allow extensions to work
with both TYPO3 v13 (using the hook) and TYPO3 v14+ (using the new event)
simultaneously.

Use the :ref:`PSR-14 event <feature-107518-1758539757>` instead to influence
form element initialization. Since the event is dispatched at a later point,
it allows more extensive modifications than the previous hook.
