At long last, IE7 has been released. Those of us who must use IE for our web applications can now celebrate the new tabbed browsing feature (a mere three years after Firefox delivered same). The new font rendering piece is nice, making for a cleaner look to existing pages. I haven't thoroughly checked out this browser from a security standpoint, but I am hoping for safer browsing than what the previous versions of IE afforded.
Thankful as I am, I must be a little bit pessimistic and wonder how many of my apps this new browser will break. I generally write for IE, but because IE7 is such a departure from previous versions I anticipate a long weekend in the near future of crash testing my apps on this platform.
