Spring Security 2 Released

The new 2.0 version of Spring Security (formerly Acegi Security) was recently released.  Some good information is available in a couple spots:

The new version promises to use a lot less XML configuration which was a huge detractor for the 1.x version.  Additionally the Domain Object Security looks interesting; think "ACLs for objects."  Docs on this module are available here:
