There is no official change-log, but according to user reports on XDA forums, this update contains Android 4.0.3 build and Sense 3.6 UI. If you are one of adventurous Sensation users and have S-Off and stock Gingerbread build, then you can flash this update file directly on your phone.
We are expecting official company statement anytime now and will update the post once we get it.
