Communities: Chatter in Communities, Template Improvements, Enhanced Moderation, and Much More

Spring ’16 is packed with changes that make templates even more customizable. You can show more Salesforce data with custom object pages, create records using global actions, and manage your community’s pages more easily. Plus, you can now add full Chatter capabilities to your community with Chatter Lightning components. These features are available in Salesforce Classic only. Other than in Setup, Communities is not supported in Lightning Experience.
Available in: Enterprise, Performance, Unlimited, and Developer Editions
