You can find a detailed list and descriptions of the enhancements and bug fixes in the release notes, which can be downloaded at the bottom of this page.
One enhancement that should be mentioned is the Project Anonymizer - a new tool in the command menu that enables the user to present results without revealing project sensitive information. This is also useful when the user sends confidential information to the support team.
