I suggest you look at github as I have never seen a formal statement of features and what's new. I can tell you most of the improvements appear to be cross-modes.Any mention of new features?
Also anybody have PiStar set up for P25? I am looking to get P25 working on the PiStar then connect to a local P25 gateway on another Pi on the network and set that up to bridge to YSF. That way I can go P25 to YSF in wide mode.
DMR to YSF is only in narrow mode.
How can I connect to pi-star.local if it doesn't know how to connect to my wireless network?
If you don't tell the Pi to connect to a network it will default to being an access point.
popnokick is suggesting you connect your computer to the Raspberry Pi when it creates it's default access point.
I prefer manually creating the wpa_supplicant file but either method should work.
