Coming this weekend to Public View... better notifications. If you're using a mobile phone for Public View, then the new system tells you when new data has been made available by putting a little red number on the application icon, like an email program.

The number tells you how many metrics have changed, so which will generally be somewhat more than one!

All you have to do is check your profile to make sure your browser's "subscribed" for notifications (you need to do this for each browser on each device you want to be notified), then your application will be automatically updated and will notify you when new data's published.
