After such a long break, it takes a while to get into proper development-routine again. As I don't have internet at my new place yet, I'm using net-cafe, which further hinders development somewhat (the tendency to drink too much beer, that is :P).
Anyway, I made a small update yesterday which allows reloading / updating ipfilter during runtime (via hnsh, "config set IPFilter newpath" only currently). GUI will have support for it shortly as well.
After lengthy searches, I finally found proper (and seemingly working) Tray Icon code for Qt4. I'm still experimenting with it, but it looks good and we should have tray icon support within few days.
The topics of what "big thing" to develop next is still open. Many request anonymous networks, but I don't think Hydranode is quite ready for that yet. Anonymous networks don't contribute content to the "hydranode mix" really, so in current stage, I still believe it would be better to improve existing plugins (4+gb file support in ed2k, unicode, proper BT support), and go forth with the original plan of implementing G1 network (2.2m users, yummy!) in foreseeable future.
