SHIELD Portable Update 82 changes?

Something with our in-game browser broke after SHIELD Portable Software Update 82 was released on 8/5. I was hoping to find a comprehensive changelog to see what might have caused the issue. The only list I found so far is the public release notes: http://shield.nvidia.com/portable-release-notes/, but this does not tell me much. Where can i find a more exhaustive changelist from update 82?

I’m not sure if this is the right forum for this question, so please direct me to the right place if this is not it ;)
