The diff format is similar to the one used by json-diff. It looks something like this (IIRC):
[' '] -- the item is unchanged['+', <object>] -- the item has been added['-', <object>] -- item was removed['~', <diff>] -- item was modified. The diff structure is recursive, so diff might be an object or an array
{__old: <object>, __new: <object>} is the diff format for 'replace this object with another'.
