My jan-2009 wireless VP2 is also at 1.80 - is there any reason to update to 
current ?

The 'wired' firmware release notes 
at 
https://support.davisinstruments.com/article/qu2edou0f5-vantage-pro-2-cabled-console-firmware-direct-pc-install-3-80-windows
 
don't mention anything that looks worth it to me, but I figured I'd ask....

(the wireless firmware link 
is 
https://support.davisinstruments.com/article/qj3zfwto7y-vantage-pro-2-wireless-console-firmware-direct-pc-install-3-80-windows
 
but it doesn't have as much release notes type info on it)

I might add - requires Windows to update.  Grrrrrr......
