How do i update a live html game

so the save expression saves everything to webstorage, so that would include text boxes, sprites and objects etc, if i upload a new patch or update for my game people with old saves will get bad UI problems, is there any work around this? do i need to use a no save behavior on every object sprites and textbox.

Uh yes, a general tutorial on a workflow "how to patch/ update your game" would be cool. For example adding new levels.
