We made a couple of slight changes to Assignment #2 and Assignment #3 that you should be aware of.
For Assignment #2, we merely fixed a typo. On the first page in the paragraph following the diagram for S0, it now reads "moving the object into a new state such that S1 follows S0 given a single (or set of) command(s) was executed" to reflect that S0 follows S1 and not the other way around.
For Assignment #3, we are now requiring that the PiggyBank class be included in the shopping package, and that you copy a zip file of the shopping folder along with the test.txt file to the class store.
