I have had this router for 11 months.I just looked at this website today for the first time. Hardware V.2.0000

I see what looks like a newer version of firmware available but the version notes don't seem relevant to my usage. However, there doesn't seem to be any version history I can find. So I have no way of knowing if there are previous firmware upgrades that might be useful to me. Nor can I tell the date of my current firmware to see how long ago it was created, to compare with what is available now.

I would appreciate either being pointed to where I can find version history or just advice on whether I should upgrade my firmware. I don't have any know problems with the router.
