Red strokes mark elements that only appeared in version five, green strokes indicate that the elements only occurred (and were added) in version six and yellow nodes have been updated during the version transition. In this example all reactions have been added, one compartment (ER) and one species (Calcium-ER) was deleted. Another compartment (compartment) was added, while three species where updated.
