Be ready, and be wary. The new version of Internet Explorer v7 is due to be properly released ‘this month’ according to the IE team’s blog… and will be forced on people ‘a few weeks’ later via Microsoft’s automatic update channel. If you haven’t checked your site with IE7 RC1, the final preview release, then you really should. And when the proper release emerges, you’d better check again.
A lot of web managers are going to get nasty shocks if they don’t.
