Valve's latest beta client activates the Steam Controller's Bluetooth Low Energy function -- a necessary feature if you want to use the gamepad to play on a mobile device in the near future. If you'll recall, the company recently announced that Steam Link will be able beam games to the dedicated iOS and Android apps it's releasing during the week of May 21st. That means you'll soon be able to play on a phone, tablet or TV, so long as it's on the same 5GHz network as the host PC or it's connected to the computer via Ethernet cable.
