FWIW the release checklist <http://sourceware.org/glibc/wiki/Release> has 
a point I put there "Shortly before the release, look for any significant 
user-visible changes not mentioned in the NEWS file and add them to that 
file.".

David S. Miller's SPARC optimizations are certainly worth a mention for 
2.16, I don't know what else that isn't currently there (x32 support 
should obviously be mentioned if it's finished by 2.16).  Much of the work 
for the past couple of months has been dealing with some of the large 
backlog of open bugs, rather than adding new features - and generally of 
course it's good to be conservative about new features - maybe some 
general summary of bug fixes that's more readable than the list of bug 
numbers should be added alongside the list of bug numbers?  Quite a bit of 
other work has been infrastructural cleanups rather than things visible to 
users of glibc.
