+============================================================
+Deprecation: #64068 - Deprecate thumbs.php and ThumbnailView
+============================================================
+
+See :issue:`64068`
+
+Description
+===========
+
+Prior to the File Abstraction Layer (FAL) there was :file:`typo3/thumbs.php` generating all preview images for the TYPO3
+Backend resources. This functionality is now marked for removal in TYPO3 CMS 8, as all functionality in the core already
+uses the File Abstraction Layer.
+
+
+Impact
+======
+
+Using `ThumbnailView`, `thumbs.php` or `BackendUtility::getThumbNail()` will throw a deprecation warning.
+
+
+Affected installations
+======================
+
+Any TYPO3 installation with custom extensions using one of the files / methods mentioned.
+
+
+Migration
+=========
+
+Use the File Abstraction Layer for any custom works. See `BackendUtility::thumbCode()` for inspiration.
