It is better to assume your details were obtained, than remain ignorant waiting to be contacted like some people seem to be choosing to do. Ignorance is bliss I guess.
At the very least renewing your license is a small $43 cost, vs your identity being used and your credit rating ruined because of it..
But it comes down to whether there is any point renewing it. As mentioned previously, the only thing that changes is the version number. And I don't recall many institutions requesting the version number.
So you get a new licence, with the same licence number as the breach, and you may be no better off.
In my case, name, DOB, licence number, mobile number and address were breached. The first three I can't do anything about, I could change mobile numbers I guess, but I've had it twenty years, and my address is different now as well.
