What is PeerBlocks relationship with the old PeerGuardian program?
PeerBlock is actually based on the same code used to create PeerGuardian – specifically, the “PG2 RC1 Test3” Vista beta version. That code had a LOT of bugs in it, and hadn’t been updated for about two years. So I started up this PeerBlock project to fix all those things that’d been annoying me for so long. A bunch of other people decided to pitch in and help out, some with development, some with testing, and now we’re where we are today. So compared with old PeerGuardian software, PeerBlock is much more stable, doesn’t require nearly so many hacks/workarounds to get working on Vista/Win7, and is actually under active development . . . so we can (and will!) actually respond to new bug reports or feature requests.
