Breaking: #101603 - Removed hook for overriding icon overlay identifier

See forge#101603

Description

The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Core\Imaging\IconFactory']['overrideIconOverlay'] has been removed in favor of a new PSR-14 event \TYPO3\CMS\Core\Imaging\Event\ModifyRecordOverlayIconIdentifierEvent .

Impact

Any hook implementation registered is not executed anymore in TYPO3 v13.0+.

Affected Installations

TYPO3 installations with custom extensions using this hook. The extension scanner will report usages as strong match.

Migration

The hook is removed without deprecation in order to allow extensions to work with TYPO3 v12 (using the hook) and v13+ (using the new event) when implementing the event as well without any further deprecations.

Replace any hook usage with the new PSR-14 event.
