It depends on what is in the changelog. If there are performance or durability improvements, you might want to change the firmware even if you are not facing a significant issue. The downside is the risk to data on the disk - don't do that (or anything, really) on a drive that holds the only copy of something important.
If the drive is being moved to a different array or machine and the data is to be lost anyway, the risk is very low and, if the process is easy (unlike this) it might be a sensible move.
I agree "just because it's new" is a poor justification to risk data.
