updates include :-
New benchmarking apps for testers running Raring.
New kernel uploaded (awaiting nux fix).
Performance enhancements (onboard keyboard startup time reduced to 6 seconds from 45)
Brave souls can try upgrading to raring today with this apt-pinning recipe. Create the following file /etc/apt/preferences.d/ubuntu-nexus7-ppa and add the contents below. Thanks to Colin Watson for the tidbit.
