That ... didn't quite happen. Because of unforeseen delays with the update, it's just now rolling out to members of the Office Insider program, giving them access to new features including the Morph transition in PowerPoint 2016 and the ability to embed online video in OneNote 2016. Enterprise users who are enrolled in First Release from organizations on the Office 365 Current Branch will also start getting the updates Wednesday.
It's not clear how long it will take for the updates to roll out to people who aren't Office Insiders, but Microsoft said last month that it expected to wait a few weeks to gather feedback before sending the updates out to consumers and enterprise users on the Current Branch of Office 365.
Consumers and university users who are interested in trying out the new features can sign up for the Office Insider program here. Doing so won't just offer early access to the updates that were released Wednesday, but also future sneak peeks at features Microsoft plans to release in the future. People who opt into the program will get support from Microsoft if they encounter any problems.
