Deprecation: #89756 - BackendUtility::TYPO3_copyRightNotice

See Issue #89756

Description

The PHP method TYPO3\CMS\Backend\Utility\BackendUtility::TYPO3_copyRightNotice that is used to display information about the warranty and copyright of the product, e.g. used in the login screen, has been superseded by a new API TYPO3\CMS\Core\Information\Typo3Information.

The existing static method has been marked as deprecated.

Impact

Calling the method will trigger a deprecation warning, but work as before until TYPO3 v11.0.

Affected Installations

TYPO3 installations with custom extensions explicitly calling this method. Run the Extension Scanner in the “Upgrade” module to see if you are affected.

Migration

Use the new Typo3Information PHP class, and its method getCopyrightNotice() which will return the same output.
