In the previous version of SupportClient.aspx, the header "Welcome to Yoursite.com" was static text but in the new version it's been replaced with a call to ChatWebUtility.SupportRoomTitle. This looks like new functionality that I might want to utilize, but where is this set within the application? Also, your help file 'CuteLiveSupportUserGuide.chm' should be updated on this topic.
In the script Support-Image-Button.js.aspx, the string constant _liveHelpDialogFeature has never worked (even in v3) and should be dimensioned and included in the c# code instead of as jscript.
