Does anyone know what this software update is?

This update contains functional improvements and eliminates software malfunctions for a better entertainment experience in your Mercedes-Benz.
My car used to bang and pop when in S+ mode on every downshift. Now it doesn't, or does so very quietly. The cold starts are more quiet, too. And the revs at idle are much quieter. I almost hate driving the car now comparing it to how it used to sound.
I had a Weistec Stage 1 ECU tune done after the recall, but that didn't help with the exhaust at all (but the additional HP is awesome).
The Mercedes SA provided a Proof of Correction form after the recall service and said that the CA DMV may require a copy when I'm due to renew the registration next year.
My advice is if you get the letter - "lose" it!
