I don't understand the focus on "upgrading" so much with people nowadays - if there's an "upgrade" for that application it's usually a big version bump which is due with the next big version, v3, due sometime this year that adds features, fixes bugs, etc. Generally there's no reason to "upgrade" to any newer release unless you're having problems with the older one which is true for
any software or if a newer release adds functionality that you may find useful.
I'm not saying there are times where an update/upgrade is useful or even necessary to quash major showstoppers aka bugs, but so far in my use of SDR-Console/Radio I've yet to
ever have issues or have it crash. Now, having said that, to get it to work with RTL sticks it doesn't right out of the box, you'll need to get some customized RTLSDR dll files made for it specifically from here:

Been using those since I first discovered SDR-Console/Radio and again, never had an issue - I believe they're not distributed directly with the software for some licensing issue but don't quote me on that because I'm probably wrong but that other developer created them and still provides them for download.
SDR-Console/Radio does more natively than most any other SDR application I've come across yet and that's like 15 different ones and none of them come close to what it's capable of, and I don't even use it for HF stuff which is what the majority of users out there tend to use it for.
I can't say much else about it other than go download it, spend a day or two learning how it works, and go from there.
