For all you testers out there; Microsoft has just released a new beta release of Microsoft Office 2010. Its build number is 14.0.4536.1000 which is a significant step forward of the 4006 Technical Preview release which had been available for some time now.
Currently it is only available to testers via Connect and people with a TechNet or MSDN subscription. A broader beta release available to everyone is upcoming as well and even expected this week.
