Deprecation: #94227 - f:base ViewHelper¶
See Issue #94227
<f:base> ViewHelper isn’t suitable in almost all use cases
and has been deprecated: In most cases the
PageRenderer takes care of the
<head> markup, directly, or indirectly via TypoScript
Using the view helper in fluid templates will log a deprecation warning and the view helper will be dropped with v12.
The limited use of the view helper likely leads to little usage numbers.
Searching extensions for the string html:
reveal any usages.
The easiest solution is to simply copy PHP class
TYPO3\CMS\Fluid\ViewHelpers\BaseViewHelper to the consuming extension,
giving the view helper a happy life in an extension specific namespace.
