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

Why You Must Upgrade Your Community Templates in Spring ’16
If your community uses a pre-Winter ’16 Koa, Kokua, or Napili template, or a pre-Spring ’16 Aloha template, we strongly recommend that you update to the latest template version. Not sure what your template version is? Check the Settings area in Community Builder. Customer support for older templates is being discontinued in the Summer ’16 release (May 2016). Also, many powerful Community Builder and template features require the Winter ’16 or Spring ’16 template versions, so if you didn’t upgrade in Winter ’16, now is the time to do it.
We’ve Renamed Some Template Components
We know that finding the template components you need should be easy and intuitive. So, we renamed some of the components so that you can easily figure out what they are for. We also grouped the components by type in the Page Editor so that you know where to use them.
Chatter in Community Templates
Chatter Lightning components for the community templates make it easy to add full Chatter capabilities to a community. With groups and profiles, you can create a much richer collaboration experience in the community. Individual Lightning components for features such as the feed, publisher, and groups mean that it's easy to completely customize where and how Chatter is integrated into the community.
Files in Communities
Using files in Communities is easier and more flexible than ever before! Attach multiple files to a single feed post, upload and select files in a unified flow, and preview files in the new Lightning multi-file preview player.
Community Templates
We want your communities to be exactly what you envision. That’s why we're giving you the power to create communities that are awesome. Last release we made community templates extensible, and this release we're making them even more flexible and customizable. You can now determine the level of record detail to include and where to display it. We've made it easier for your community members to navigate in your community, create and work with records, and find the topics they're interested in.
Community Builder
Community Builder gives you more control over your pages with the enhanced Page Manager. You also get custom page layouts, an improved page loading experience for members, and better error handling for components.
Community Setup
Communities Setup is now available in Lightning Experience! You also get limit increases, a streamlined setup for two-factor authentication, the ability to use Platform Encryption in your community, and much more.
Community Management
Managing your community is now even easier than before. You can set up community file limits and now community moderation supports all feed types, special characters in your keyword lists, the API, and much more. To give you more control and flexibility with your community recommendations, you can now specify where your recommendations appear and target specific audiences.
Community Reports and Dashboards
Start the drum roll ladies and gents! You can now grant all your role-based external users permission to create and edit reports! You also get new custom report types and you can share Wave dashboards.
Community Insights and Analytics
When you install the updated Salesforce Communities Management package from the AppExchange, you’re in store for quite a magic trick. Community Management dashboards now display as Lightning dashboards—even if your org isn’t using Lightning Experience. To top it off, you also get new and improved Insights reports.
Other Changes in Communities
Other important changes to Communities include a limit increase, access to Notes and Attachments for users with a Customer Community license, more robust field-level security for guest users, and changes to how emails are sent for large community groups.
