On a Mac there's Safari 10.0.1, the latest version of Safari. It's included in macOS Sierra and was released as a stand alone update for OS X Yosemite and OS X El Capitan.
I'll add the info for AirPort routers when I'm home. I recently updated all of mine and noticed that the early Extreme seems to have reached the end of its updates. From memory, the later Extreme and the Express are on 7.7.7 and the old Extreme 7.6.7, but memory is getting dodgy.
Any Airport devices that support the 802.11ac standard got the 7.7.7 update. Older devices that only offered support up to 802 11n got the 7.6.7 update.
