Force.com Summer’12 Features
Apex Describe Support for Field Sets
Visualforce dynamic bindings have supported field sets for some time. In Summer ’12, Apex provides describe support
for field sets, which makes it possible to dynamically generate the SOQL necessary to load all fields in a field set. This
makes field sets easier to use in Visualforce pages that use custom controllers.
This sample uses Schema.FieldSet and Schema.FieldSetMember methods to dynamically get all the fields in the
Dimensions field set for the Merchandise custom object. The list of fields is then used to construct a SOQL query that
ensures those fields are available for display. The Visualforce page uses this class as its controller.

Single View State—Generally Available
The Single View State optimization introduced as a pilot feature in Spring ’12 is generally available in Summer ’12.
Single View State will be activated on existing organizations within 24 hours of deployment of Summer ’12 on your
Salesforce instance.

JavaScript Remoting Enhancements
We’ve enhanced JavaScript remoting in several ways.
To make it easier to work with namespaces, especially for pages that make remoting calls to methods provided in packages,
you can use the $RemoteAction global to automatically resolve the correct namespace, if any, for your remote action.
To use this facility, you must explicitly invoke JavaScript remoting. The pattern for doing this is:

There are lot of other features like:

JSON Parser
New Types
Sorting Support for Non-Primitive Data Types in Lists
Knowledge Management Publishing Service Class
Describe Support for Field Sets
New Interfaces and Methods for Running Apex on Package Install/Upgrade and Uninstall
Allow Reparenting Option in Master-Detail Relationship Definitions
New Lookup Relationship Options etc..
