========================================================
|
|
Breaking: #96899 - "displayWarningMessages" hook removed
|
|
========================================================
|
|
|
|
See :issue:`96899`
|
|
|
|
Description
|
|
===========
|
|
|
|
The hook :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_befunc.php']['displayWarningMessages']`
|
|
has been removed in favor of a new PSR-14 event
|
|
:php:`\TYPO3\CMS\Backend\Controller\Event\ModifyGenericBackendMessagesEvent`.
|
|
|
|
The hook was used to display messages in the About module.
|
|
|
|
Impact
|
|
======
|
|
|
|
Registered hooks are not executed anymore.
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
TYPO3 installations with custom extensions using this hook, which is very
|
|
unlikely. The extension scanner will report possible usages.
|
|
|
|
Migration
|
|
=========
|
|
|
|
The hook is removed without deprecation in order to allow extensions
|
|
to work with TYPO3 v11 (using the hook) and v12+ (using the new event).
|
|
|
|
Use the :doc:`PSR-14 event <Feature-96899-NewPSR-14EventModifyGenericBackendMessagesEvent>`
|
|
as a direct replacement.
