Peplink Routers Supports 2 Firmwares

In our test of "Eating Your Own Dog Food", we are still testing the Peplink Balance 30 and came across a pretty cool feature that we haven't seen in any other router.  If I am testing a newer firmware (or beta firmware), when I reboot my router, I am giving the option to reboot under the current version OR the last version.  Pretty handy if you are testing a new firmware and for whatever reason need to revert to the previous one.
