1. Centrally Manage and Share Testing Assets, Dependencies, and Versions in Quality Center 10.00
2. Perform Single-User Local System Monitoring While Running Your Tests
3. Improve Portability by Saving Copies of Tests Together with Their Resource Files
4. Call Actions Dynamically During the Test Run

The most useful thing was a Maintenance Run Mode which will be helpful to update run time objects.
Again, we have better support of IE7 and even IE8 and Vista when come to 10.

Testcase prioritization technique to be used in case of risk based analysis

@If it is a new application developed from scratch, then everything is of equal risk and bugs could be anywhere. 

@ If it is a new application developed from existing components/modules, then risks are at the integration level. Each module may work properly but they may not be re-used in the right context or assembled correctly. 

@If it is an existing application that is having new features added, then the new features themselves are the greatest risk.

@If it is a maintenance release (bug fixes only) of an existing application, then the validity of the bug fixes is first, closely followed by the features that had the bugs.
