I vaguely remember some discussion about fixing the layout of the checksums so that it was clear one had to run sha256sum rather than sha1.
However, I see that it's still rather misleading in appearance--that is, the words SHA1 sum are written there along with what I assume are the sha256 sums. (I didn't actually download an ISO to check, but it seems to be a lot of numbers for an sha1.)
The nice people at distrowatch are apparently among the ones confused by this, as their links to downloads also include links clearly marked SHA1.
A minor issue to be sure, but those who frequent the forums know how Those Who Wish To Try The Latest will almost certainly be confused.
