+=======================================================
+Deprecation: #95003 - Extbase ViewInterface canRender()
+=======================================================
+
+See :issue:`95003`
+
+Description
+===========
+
+To streamline and simplify Fluid view related classes, the
+Extbase related :php:`TYPO3\CMS\Extbase\Mvc\View\ViewInterface`
+method :php:`canRender()` has been dropped from the interface.
+
+Impact
+======
+
+The method should not be used anymore. Implementations in consuming
+view classes are kept in TYPO3 v11 but have been marked as deprecated and
+trigger a PHP :php:`E_USER_DEPRECATED` error upon usage.
+
+
+Affected Installations
+======================
+
+Method :php:`canRender()` had limited use within Extbase, it is rather
+unlikely many instances with extensions using the method exist. It's
+purpose was to check for Fluid template existence before calling
+:php:`$view->render()`, but all existing view implementations throw an
+exception during :php:`render()` if a template path can't be resolved.
+
+
+Migration
+=========
+
+Do not call :php:`canRender()` on template view instances, but let
+:php:`render()` throw :php:`\TYPO3Fluid\Fluid\View\Exception\InvalidTemplateResourceException` on error
+instead.
