Unfortunately no one can be told what fun_plug is - you have to see it for yourself.

I see the last post is ''March 23, 2013: Alt-F-0.1RC3 has been released''. And no further posts for six months or so.
I have been hanging on, waiting for a firmware release that is not a 'release candidate'. I have seen Experimental RC4 - but I am loathe to commit my backup data to something that is 'experimental'.
On the ALT-F site, last post was for DNS-320/325 and last DNS-323 posting was 9 October 2013. Has development / finalisation on DNS-323 stopped or abandoned?
Just asking. Just asking.
