Yes, if you want an up to date insterment, with any bugs fixed and any new features.
If not, and you don't need any new features and it works for all the measurements you need, then no.

Your probably going to get answers saying, if it isn't broke do not fix it. Which is the cavemans answer. Those who still rub sticks together instead of using matches.??
Updating firmware is not fixing it, it is improving it.
You have to make up your own mind.
Myself, I keep ALL my equipment up to date.
I find it more useful that way.
Have fun?
May you be safe and healthy
