When did this update happen?

I check in to the topics everyday, but must have been asleep at the wheel if someone else already posted this. To make a long story short, I bought Shoot em up the day the PS3 got the original DTSHDMA update. Being disappointed with the whole 7.1 decoding thing, I shelved the movie refusing to play in 5.1. Yesterday I popped it in for the hell of it and there it was in 7.1. How long has the fix been available and does it address the other 7.1 movies that had decoding problems?
