New Tests to Validate New Windows Logo Program 2008 Requirements
• Audio: Fidelity Test will now run on capture endpoints in addition to render endpoints.
• Video Capture: Blink Audio and Video Capture and Control Test now includes new tests to validate that USB video capture devices comply with the USB video class specifications STREAM-0008 and STREAM-0053.

Note: The preceding new tests were not included as previews in WLK 1.1. Therefore, we will still accept any submission before August 1, 2008 that fails these tests.

In addition to these new tests, WLK 1.2 also contains the preview tests that were released in WLK 1.1. See the WLK 1.1 release announcement for details. The preview tests included in WLK 1.1 are now required in WLK 1.2.
