I don't think the NEWS file should point to a site requiring non-free 
JavaScript; host a copy of the ABI somewhere else (maybe on the glibc 
wiki).

I think the NEWS file needs to give information from the perspective of 
people building and using glibc.  That includes: the library can be 
disabled with --disable-mathvec (the configure option also needs 
documenting in manual/install.texi, with INSTALL being regenerated); use 
of the functions is enabled with -fopenmp -ffast-math -O3 (or whatever) 
and the library is linked in as needed when using -lm rather than needing 
to specify -lmvec explicitly.
