+# 21.0.6 (2025-12-17)
+## Breaking Changes
+### forms
+- The shape of `SignalFormsConfig.classes` has changed
+  
+  Previously each function in the `classes` map took a `FieldState`. Now
+  it takes a `Field` directive.
+  
+  For example if you previously had:
+  ```
+  provideSignalFormsConfig({
+    classes: {
+      'my-valid': (state) => state.valid()
+    }
+  })
+  ```
+  
+  You would need to update to:
+  ```
+  provideSignalFormsConfig({
+    classes: {
+      'my-valid': ({state}) => state().valid()
+    }
+  })
+  ```
+  
+  (cherry picked from commit 348f149e8b06d6885f54bac4cf03a9481a8b19b7)
