I’ve set up a project using Trac (if you don’t know what trac is read here) that allows you to compare the source code of the new beta release of the Flex 3 SDK with the previous Flex SDK 2.0.1 version. This lets you browse all the changes that were made and visually see the differences. I find this very useful when trying to analyze the new release and figure out what the new additions and changes are.

Here’s a link to the main Trac website.

You can view the entire changeset from version 2.0.1 to version 3 here. (Warning: it’s pretty big so it might take a bit to load).

If anyone from Adobe doesn’t like this and wants me to take it down just let me know. I think it’s valuable for the development community, but if you’ve got a legal fever and the only remedy is to yell at me, then I’ll remove it. Email me here: doug@dougmccune.com.
