Version: 2.6
This update didn´t fix the hdmi issue at all. Still colors that are way of or downright missing. I really hope that Apple diggs into this and provides a REAL WORKING FIX!

Confirming NON-SOLUTION.
Applied the EFI update and no solution to garbage HDMI performance. Running MBA mid-2012 to BenQ GL2440 HDMI screen, OS X 10.8.2 with 8GB RAM, 128GB Flash. Six months and this is the first sign from Apple that the issue exists and their solution doesn't work!!!
needless to say, NOT impressed with NON-SOLUTION!!!

Significantly increased speed of my MBA, especially start up and shut down. Update must have some sort of problem with PRAM. After installation had to reset PRAM to get start up tone. On subsequent start up tone is gone so have to reset PRAM again...(loop). Really like the speed increase!!!

This update has not fixed the known problem of the MBA not sleeping when connected to to the charger, but it does sleep when on battery power.
