+======================================================================
+Feature: #79812 - Allow overriding cropVariants for Image Manipulation
+======================================================================
+
+See :issue:`79812`
+
+Description
+===========
+
+With the introduction of :issue:`75880` you now can define multiple cropVariants in TCA. With this feature it is  now possible to change or override these cropVariants via TSconfig.
+
+Setting a FormEngine option through :ts:`TCEFORM.sys_file_reference.crop.config.cropVariants.*` does now work.
+
+
+.. code-block:: typoscript
+
+    TCEFORM.sys_file_reference.crop.config.cropVariants {
+        default {
+            title = Default desktop
+            selectedRatio = NaN
+            allowedAspectRatios {
+                NaN {
+                    title = free
+                    value = 0.0
+                }
+            }
+        }
+        specialMobile {
+            title = Our special mobile variant
+            selectedRatio = NaN
+            allowedAspectRatios {
+                4:3 {
+                    title = ratio 4/3
+                    value = 1.3333333
+                }
+            }
+        }
+    }
+
+
+Impact
+======
+
+It is not possible to change or override cropVariants via Page and User TSconfig.
