Get ready for IE 7 because it is coming automagically
CNET has a nice warningarticle on how IE 7 will be pushed to users via Windows Update. It was reported on Slashdot where you can find the typical insightful conversation about it (a little bit of scarcasm, yes). What this essentially means is that you should probably start to think about getting those hacks out of your CSS and learn a bit about conditional comments. You also might want to read up on the known issues with CSS and IE 7 on the CSS discuss wiki. I would assume the CSS tweaks are pretty much done but if you want to hold out until the end it is still worth your time to identify potential problems and workarounds.
For UW sites there doesn’t appear to many CSS issues beyond printing. Not sure if anyone will be effected by other changes but it is worth you getting your hands on IE 7 to find out. Hopefully I can look at that in August although I would prefer to see a near final beta to be sure it is worth my time.
Update: I left out a buzz post discussing the end of IE 6—which points out that the automatic update is a good thing although it likely won’t mean the death of IE 6.
