No doubt this was overshadowed by the announcement of the 552, but SD did just released a new firmware version for the 788T.
http://www.sounddevices.com/download/788t-firmware.htmMost of this rev is directed towards changes and enhancements to the limiters. One interesting (to me at least) change is the ability to modify the meter scaling. I have not had a chance to try rev 1.76 yet, but I hope to this weekend.
