AAD? I guess this line is copypasted, maybe this should be tag or tagbuf?

Fixed. Should be "Auth tag".
Thank you.

Note that the SPREAD_BUFFER_ARG macro has been moved to util.h now and could likely be used to simplify this also.

There is a very subtle change in the error message here given that Buffer is changed to buffer. Unfortunately this means this has to be treated as a semver-major because it's a change in the error message. whee!
