+
+==========================================
+Deprecation: #90348 - PageLayoutView class
+==========================================
+
+See :issue:`90348`
+
+Description
+===========
+
+The :php:`PageLayoutView` class, which is considered internal API, has been marked as deprecated in favor
+of the new Fluid-based alternative which renders the "page" BE module.
+
+
+Impact
+======
+
+Implementations which depend on :php:`PageLayoutView` should prepare to use the alternative implementation (by overlaying and overriding Fluid templates of EXT:backend).
+
+
+Affected Installations
+======================
+
+* Any site which overrides the :php:`PageLayoutView` class. The overridden class will
+  still be instantiated when rendering previews in BE page module - but no methods
+  will be called on the instance **unless** they are called by a third party hook subscriber.
+* Any site which depends on PSR-14 events associated with :php:`PageLayoutView` will only
+  have those events dispatched if the :php:`fluidBasedPageModule` feature flag is :php:`false`.
+  * Affects :php:`\TYPO3\CMS\Backend\View\Event\AfterSectionMarkupGeneratedEvent`.
+  * Affects :php:`\TYPO3\CMS\Backend\View\Event\BeforeSectionMarkupGeneratedEvent`.
+
+
+Migration
+=========
+
+Fluid templates can be extended or replaced to render custom header, footer or preview of
+a given :typoscript:`CType`, see feature description for feature :issue:`90348`.
