This is the second release candidate on the way to Spring 2.0 final. It introduces a number of bug fixes and minor refinements, in particular in the AOP framework and in the JPA support. Please see the changelog for details. A number of further known issues will be addressed in the upcoming 2.0 RC3 release; see our JIRA road map for details.
Please give this release a try with your applications and let us know about any problems that you might encounter! It is important to emphasize that Spring 2.0 provides backwards compatability with the Spring 1.x series. Spring 2.0 also continues to support JDK 1.3+ and J2EE 1.3+ (even J2EE 1.2+ except for the JSP tags and the EJB support). Compatability is critically important to our user base and we are committed to providing it. Hence, we’re also interested in learning about potential compatibility issues on any such platform.
