Well I just upgraded from 1.31 final, since my port forwarding issues arose again after it was powered cycled quite a bit yesterday (was having some electrical work done).
Did my now-standard procedure: held down the reset button for 20s, then restore defaults via browser, then flash. After it flashed, I restored the defaults via the browser and held the reset button after.
As it stands, everything is working as it should. Though I don't use Shareport, SecureSpot or WiFi Protected Setup. Hopefully it stays working...
So +1 to D-Link for fixing things (or so it seems, router has been up for 8h now)
