This software update is a biggie. It means that in addition to the Bluetooth connection, you can now stream your heart rate with an OH1 and H10 to an unlimited number of devices via ANT+ in real-time.
Polar recently unveiled with the OH1+ which already had this functionality built-in. The update means the only difference now between the OH1 and OH1+ are the swim google clips included in the newer version.

You can download the upgrade to your OH1 via the Flow app on your smartphone or FlowSync on your computer. For H10 you can get this via the Polar Beat app or Polar Flow app on your smartphone.
