Breaking: #107518 - Removed "initializeFormElement" hook
See forge#107518
Description
The hook
$GLOBALS
has been removed in favor of the more powerful PSR-14
\TYPO3\
.
Impact
Any hook implementation registered is not executed anymore in TYPO3 v14.0+.
Affected installations
TYPO3 installations with custom extensions using this hook. The extensions scanner reports any usage as weak match.
Migration
The hook is removed without deprecation in order to allow extensions to work with TYPO3 v13 (using the hook) and v14+ (using the new event) when implementing the event as well without any further deprecations. Use the PSR-14 Event to allow greater influence in the functionality. Especially because the event is dispatched later, it allows more modifications than the previous hook.
