There is a new version out 2.01b03 timestamped Tue 15 Feb 2011 on the russian D-Link site ftp://ftp.dlink.ru/pub/Router/DIR-685/Firmware/beta/
Unfortunately it still has the loss of encryption bug dropping the Wifi to un-encrypted every so often...
EDIT: And, amazingly this boards software does not handle FTP URLs but prefixes them with "http", so removed hyperlink altogether, please copy and past into browser instead.... jeeez
