I haven't worked on dupeGuru for a while and frankly, I don't want to. I never had any duplicate problems so I don't even care about the raison d'être of this thing.
I don't want to answer incoming issues and I don't want to let them pile off unanswered either, that feels rude. So here I am, being straightforward about it.
If you're considering using dupeGuru, you might want to give it a try but if it doesn't meet your needs I suggest that you use another program because it's unlikely to ever be improved again.
If you're a developer wanting to pick it up, by all means, do so! Fork it off and release something. I will be more than happy to "officially" point to any fork that remotely looks like a serious effort. I will also be happy to assist if you have questions about the code.
Good bye dupeGuru, Virgil Dupras

If anyone is wondering why the source has changed, Dupeguru's website says the maintainer has changed. And so the link https://www.hardcoded.net/dupeguru/ leads us to https://dupeguru.voltaicideas.net/ which in turn has a link to https://github.com/arsenetar/dupeguru/ which is the GitHub repo the sources are downloaded from. So the source change is legitimate.
