If you go to the downloads page and scroll to see the different ISOs, you can see a section for the SHA256 sums of each category of ISO images; for the Testing ISOs there's none. I don't know if there's a different place to find them or a reason for their absence. Does anybody know anything?
Oh, you know, ISOs being testing, sun setting in the west, devs being lazy... should be there now.
Thank you!
