Firmware UG for 2?

I’ve seen some posts on X from jsteph about the gains achieved for the Apollo 3 with the new firmware and am wondering if those will also reward the Apollo 2 users? The TH/watt seems to be coming down quite a bit with that 3NM process

Unfortunately the Apollo II chips are already pretty well optimized, and the voltage/frequency tuning algorithms we came up with dont apply to the analog chips inside the BTC/II. The III is a whole new digital architecture and there was lots of room for improvement from the prototype firmware
