Should I update the firmware?

I bought a cc121 and I installed the latest driver version. Every works fine with C7. I saw in the download page there’s also an update for the firmware but with a lots of warning…

So I wonder: should I update? What does it fix?

Thanks.

I don’t know which version is on the unit you bought, but they did release a firmware update a good while ago that added a lot of additional functionality, you really want to get that.
