I thought that NIST backed off and returned to the c=2d capacity in the final standard, as a result of public criticism. My understanding is that the final SHA3 choice is in fact a proper subset of the Keccak proposal. Were there other changes I've overlooked?

The basis of the complaint was that SHA3 chose different defaults for tunable parameters, compared to what was originally used. As you said, it's still a proper subset of Keccak that way.

I haven't paid full attention to events though, so I guess I missed the part where they backed off later on. Thanks for the correction.
