The system scans every 60 minutes. PeerExplorer still uses version 0.5.12
There are three new versions 0.6.0 , 0.6.1 , 0.7.0e released in less than 20 hours. The new api documentation looks really promising and there were also changes in it. I dont know yet maybe there are issues now. We will see. I decide in next days what version PeerExplorer is running and maybe have to change some stuff.
Thanks for your inside.
