Hi , Lets took at what salesforce have improved in winter 16 release. Here I will give you guys a sneak about the new features and changes in winter 16.
1. Lightning Experience A New, Modern, Intelligent User Experience
Welcome to Lightning Experience, the new, fast, beautiful user experience from Salesforce. With a sales-centric mindset, our initial release focuses on reinventing the desktop environment to better support your sales process
2. Sales cloud- Sales path feature is on Lightning experience
Get your reps to adopt and adhere to your company’s sales processes by using Sales Path. Previously available for opportunities for Salesforce1 users, Sales Path is now available for opportunities and leads for desktop users. This feature is available in Lightning Experience only.
3. Sales cloud - Alert Users to Possible Duplicate Records Quicker Than Ever on Lightning experience
When you used Data.com Duplicate Management in the past, your duplicate rules ran only when users tried to save a record. Now,
they run as users complete fields on a record, so users don’t have to continue entering data for a record that’s already in Salesforce.This feature is available in Lightning Experience only.
4. Community - Community Management Home Page Now Maps to a Dashboard
When you access Community Management, you now see a message to install an AppExchange package that provides you with a
preconfigured dashboard for your Home page.
5. Community - New Administration Page for Your Community Settings
Community Management has a new Administration > Settings page. On this page, you can edit your community name, description,
and URL. You can also change your community status or template. Previously, these settings were on the Overview page, which
has been renamed to Home.
6. Community - New Community Login Look and Feel
We’ve redesigned and improved the usability of the login experience to make it more intuitive for your external community members.
In addition to the main community login page.
7. Community - Switch to Lightning Experience from the Global Header
If your organization enables Lightning Experience, users who have the Communities global header turned on and who have permission to access Lightning Experience can easily change between Salesforce Classic and the new interface using the Switcher. The Switcher is available from the global header. Look for the Switch to Lightning Experience link in the Your Name menu.
8. Chatter - Freeze Sharing of a File
Now you can freeze the sharing of a file in its current state, preventing new shares without removing any existing shares. This feature
is available in Salesforce Classic only.
9. Chatter - Enable or Disable Selecting Files from Salesforce
Now you can control whether users can select files from Salesforce or only upload files in Chatter feed posts. Set this up in user
profiles or permissions sets. This feature is available in both Lightning Experience and Salesforce Classic.
10. Chatter - Apex Trigger Support for Chatter Group Records
Administrators or developers can now use Apex triggers to control record operations in groups in sensitive contexts such as in public communities, where you want close control over who adds records to groups. This feature is available in both Lightning Experience and Salesforce Classic.
11. Search - Disabling Search for Some Custom Objects
Choose which custom objects your users can search by enabling the 'Allow Search' setting on the custom object setup page. This feature is available in both Lightning Experience and Salesforce Classic.

Create 150 percent more roll-up summary fields with an increased limit per object. The default limit on roll-up summary fields per
object has been increased from 10 to 25. Gain more insights about related records by adding more roll-up summary fields to your
standard and custom objects. This feature is available in both Lightning Experience and Salesforce Classic.

15. Lightning Connect - Fully Integrate Your External Data with Writable External Objects
Now your users can do anything with external objects that they can do with internal objects, without leaving the Salesforce user
interface! For example, users can see all orders that reside in an SAP system and are associated with an account in Salesforce. They
can also place a new order or route an existing order without leaving the Salesforce user interface. As a developer or admin, use a
specialized set of asynchronous Apex operations to create, update, and delete external object records. This feature is available in
both Lightning Experience and Salesforce Classic.
16. Process Builder -Schedule Multiple Groups of Actions
You’re no longer limited to just one schedule when you configure time-dependent actions in the Process Builder. With multiple schedules it’s easier to optimize sales responsiveness, automate follow-up on important cases and opportunities, and support your business needs all within a single process.
17. Process Builder - Reduced Chances of Hitting SOQL Limits in Processes
We’ve continued to optimize how we bulkify elements in processes so you avoid hitting existing platform limits as your business
scales and grows.
18. Deployment - Choose Test Options for Change Sets
You can now choose which tests to run when deploying or validating an inbound change set in production or sandbox. Test options provide flexibility in how much testing is done to achieve quality and code coverage requirements and can reduce execution time in a deployment. This feature is available in both Lightning Experience and Salesforce Classic.
