Instructions for conversion from the previous version:
• RangedValue: Adjust the code referring to the add() method to refer to its new name, modify().
• RangedValue: Adjust the code referring to the addWrap() method to refer to its new name, modifyWrap().
• Range/RangedValue: Adjust the code that relied on parsing the result of the toString() method call and string() conversion to incorporate the new format.
