Dell Command Update still what to use?

In the past have used Dell Command Update on T and R series x00, x10, x20, and x30 series. I am working on a new T440 and see that Dell Command Update 2.4 throws errors and 3.0 does not find any updates (possible there are no updates!)

Is Dell Command Update still what I should be using for Dell firmware/driver checks for a single server environment?

Thanks!
