+* Change to JS format, not breaking
+  * Move to 3-arg addClass plus setSlots was planned in 2019, but forgotten.
+  * Thus, it is loadable in older Amber versions for more than a year.
+  * The move to 3-arg addClass plus setSlots was made now.
+* API renames / additions moving further from ivars to slots.
