Turns out, my instincts were right to postpone work on the v4.x branch till I could figure out why Raccoon was unable to find/download certain apps. The whole thing is mind bogglingly stupid and I’m going to have a tough time making the config options user friendly in the future. So good news is, that I just released Raccoon v3.4 to address the issue, bad news is that it gets technical if you actually have the problem of being unable to download certain apps.
