   case the value is undefined instead of a `\relax`ed csname. It has always been
   semantically wrong to assign to the result of `\pgfkeysgetvalueof`, but now it
   will have undesired side-effects. Therefore this change is breaking.
+- If `/handler config=full or existing` is active, `/.style={...}` assignments
+  can now fail if the style is not found in any `.search also` path. Previously,
+  the style was always set in the first search path, if it was not found in the
+  currently active path.
