I've been waiting for this eagerly! Love it. The update was already available in the Austrian store so I plunged right in.
Mark-Kashman: what I've been wondering though is if you could go more in depth about the "relevant news" part of this announcements. I know you're going to say the Microsoft Graph figures this out, but I know my users (especially the communications teams) is going to ask me questions like "who got a notification and who didn't and why" "how do I ensure that everyone gets a notification?" and so on :) And I expect your answer will be "the graph will figure out the relevant people" and "wait for the new (enterprise/corporate) sites that will be announced next year, those will allow corporate wide communications from the very top" (of course you won't confirm this here ;P ) and so, but I would like to get more insights into the "relevant" part as were a just a small organization of about 70 users, where say for example my IT communication that I publish on my IT-Hub (communication site) is very likely to very relevant to all of our users, while in huge organizations this does not apply and the graph will really shine as that approach very likely better.
