What do you mean? No need to modify variable automatically because the old is supported still.
Isn't that a contradiction to what you said above?
We DO NEED to modify the variable manually (that is what you stated with your "Yes" above), but at the same time there is NO NEED to change it (automatically) because the old one does still work...?
Hmmm. Why then do we need to modify it manually?
Because eventually it will stop working and only the new method is supported. Thats how I read his statement.
