How is this different from the old team feature?

The current team feature allows you to organize your presentations in one central location along with group billing and one-click sharing. Our new Team plan offers a greater way of collaborating on presentations along with better sharing and branding controls, team member permissions, and one-click sharing. With Team, you’ll have a shared slide library where you can update the content on a single slide and the shared slide will update in real-time across all of your presentations.
