Do ESCs need to be reflashed over time?

I've done a little searching and haven't had any luck in finding the answer.

I have 3 year old ESCs from a Tri-Copter build I was considering using in a Quadcopter build. The ESCs are http://tinyurl.com/a2u53ot here. I just purchased a 4th from the same company but didn't think to ask if it would be compatible with my year old ESCs.

I'm tempted to just buy a new set but hate to not use something if I can just reflash them to the latest firmware (not being sure if the SimonK firmware has been updated).

On a side note; are these 4 in 1 ESCs any good? http://tinyurl.com/lvhboos Hobby King sells a 20A version of this but it's only good to a 4S lipo.

Thanks
