GH1 Old and New GH1 sensor difference?

[Jacekk]

Newbie question here. I would like to buy a GH1.
What is the actual difference between an "old" and a "new" GH1 other than the firmware?
Is the sensor also new?

Am i right in understanding that now all (new and old) GH1s are hackable?

Thanks

There is no difference, other than "locked" firmware.

You are correct.
