They have published on their website a changelist document (link goes to TechNet download page) detailing the nature of the security-related fixes and updates. The document is targeted towards XP admins and covers some interesting things such as the new Internet Explorer Pop-up Manager and various security policy changes. Some other juicy tidbits from the document: Internet Connection Firewall will be enabled by default, and there will be new support for something called "Execution Protection" which allows developers to make use of the NX (no execute) page guard flag on Intel's Itanium and newer AMD processors. An interesting read."
