3.5 and 3.6 support ML-DSA, but not with CMS_NOATTR, so I need to update this.
Version 4 will support ML-DSA with CMS_NOATTR, but that's not yet tagged.

Depends what you mean by "latest OpenSSL". Latest in git, yes; latest in
distributions that people can simply install as an rpm/deb/etc., no.
Now, assuming OpenSSL releases v4 sometime in the spring, I would probably be
fine with saying you have to have OpenSSL v4 if you want ML-DSA; but others
might have a different opinion.
