Subject: RE: "No hashes found" when argon2id is present?
That's a pretty old bug, any timeline on OpenWall's side as to when you'll actually *update* implementation? When trying to run a breach simulation on a set of password hashes I have which I'm doing white-hat hacking stuff on, the hashes are all argon2id and not having this in John is problematic - using other tools exhaust >= 32GB of memory, which causes issues with attempting to crack it.

That's correct. We need to update the Argon2 implementation as part of this issue:
