What are the major differences between IE7 and IE8 that a web developer should know?

Question

I've just downloaded IE8, which replaced my IE7, but that's okay because IE8 has a 'compatibility view' which is meant to render pages like IE7 (not sure about the JavaScript).

I was wondering if there is a listing on the internet of all major differences a developer should know between the versions. I've searched Google a bit but haven't found a satisfactory listing.

So, what should I (or any other web developer) know about getting my site working optimally on IE8, and what are the major differences between the two?

Answer 1

I would start by looking here:

Internet Explorer 8 Readiness Toolkit

Differences between IE8 Compatibility View and IE7

IE8 Developer Resources

Answer 2

I don't think you'll find a comprehensive "gotcha" list of rendering quirks until more folks have it installed. There are a bunch of new features like Accelerators that you can develop to build new features into IE8. This looks like a good start.

Answer 3

I have to agree with Beska, he wants to know what the differences are, and this one person has a brain of a 2 year old. Not a great character attribute to present yourself in that manner. If it bothers you that much to where you can not provide an answer, move on and get a life.
