I have finally had time to look at POPFile version 1.0.0. The current version of the POPFile Daemon for Mercury (POPFileD 1.22.4) works fine with POPFile 1.0.0.
The only caveat is that after installing (or updating or reinstalling) POPFile, you *must* reinstall POPFileD again.
I also made a minor tweak in the installation instructions, so I would recommend downloading a new copy of the Daemon at the usual place:

I'd appreciate hearing if anyone is using POPFileD. Send your "postcards" to popfiled [at] markmatrix.com
