Spring Security 3.0.0 M1 is Available

Yesterday Luke Taylor announced availability of Spring Security 3.0.0.M1. Go get it and kick the tires.

There are a number of new features such as expression-based access control, enhanced method-level security, and permission-based filtering. All of that relies on Java 5 annotations heavily.

The codebase has been restructured and there are many spring-security-something jars where it used to be a single spring-security-core jar, which is a good thing. A number of classes have been renamed to better describe the concepts they represent.

Spring Security 3 requires Spring 3 so the migration path for applications using Spring Security 2 will involve at least two steps.
