+*cfg-update-1.11.0 (2026-07-28)
+
+  Safety checks added during all merges to prevent editing of any file versions
+  other than the leftmost one.  This was always intended behavior but lacked
+  safeguards previously.  Hashes are also checked to detect changes made
+  outside of cfg-update.  These will still be preserved but will not be
+  relied upon in future automatic merges.  The next clean package update
+  will return automatic merge behavior for that package.
