 # CHANGELOG
 
+## 2.21.0
+
+-   Add Turbo `data-turbo-permanent` support. Unmounting the React component now uses  
+    a delay and can be prevented if the Stimulus controller is `deconnected` and
+    immediately `connected` again.
+
 ## 2.13.2
 
 -   Revert "Change JavaScript package to `type: module`"
