You are right. The version you received is an updated version of 2.2u. I am in the middle of updating the instructions right at the moment. The differences between the updated version and the original version of 2.2u are:
1) C1, C2, C3 are now renamed C0, C1, C2
2) Inductor L1 and the Reset tactile button are now through-hole components to be soldered (previously they were surface mount components).
