Deprecation: #71249 - Deprecate render method of FlashMessage class¶

See forge#71249

Description¶

Method TYPO3\CMS\Core\Messaging\FlashMessage::render() has been marked as deprecated.

Affected Installations¶

Instances with custom backend modules that use this method.

Migration¶

Use custom render code, the <f:flashMessage /> ViewHelper or the ModuleTemplate for backend modules to render FlashMessages. It is suggested not to include HTML in flash messages. Flash messages should be short notifications on user interactions. If you need more elaborate or persistent messages, use <f:be.infobox /> view helper or HTML similar to that.
