Changes between Initial Version and Version 1 of Ticket #37122

-              initial
+              v1
 Why?
+``` python
+{{{
 def has_changed(self, initial, data):
     # here we miss the check for disabled
 …
     ...
+```
+}}}
 As we see, has_changed from the base is called and if successful, True is returned. But we have no additional check for disabled.
 Fix:
+``` python
+{{{
 def has_changed(self, initial, data):
     if self.disabled:
 …
         return True
     ...
+}}}
-```
 This corrupts the changed fields in the history of admin.
