The release notes for FP/AIR 16 beta is missing

I'm glad to see the new beta, but the release notes are missing! The link (http://labsdownload.adobe.com/pub/labs/flashruntimes/shared/air16_flashplayer16_releasenotes.pdf) gives me a 404 error ;(

I hope to see the changes in the new version ASAP. Thanks in advance.
