While Beta is the next major development milestone for
Internet Explorer 9, the development process will advance to that stage through a series of interim builds scheduled for release at 8 week intervals. It is an immense step forward for Microsoft in terms of transparency and how the company now communicates the evolution of Internet Explorer, which started at PDC 2009 and continued at MIX10 earlier this week.
