Good morning,

Today we are releasing version 2.23 of Venus OS – the software which is at the heart of the Color Control GX, Venus GX, Octo GX and the CANvu GX. A nice page outlining those products and comparing them is available here. Also we will release VE.Bus version 455 today, for the MultiGrid and MultiPlus-II inverter/charger models.
