The Lumia 640 and 640 Xl are the latest models to the Windows Phone stable, of course, with great specs for the money and with Windows Phone 8.1 Update 2 under the hood. Which itself just got an update in new firmware now available for the two handsets, taking the OS from 8.10.15127.138 to 8.10.15148.160. Both the Lumia 640 and the 640XL receive Voice over LTE and Wi-fi calling are the main changes, apparently. Curiously, the Lumia 830 and 735 (at least on the UK units) are also getting the update, significant because it’s the first time these two phones have officially broached 8.1 Update 2

From the Microsoft forum post:
