We're pleased to announce that Spring 1.2.1 has just been released.
This is a bugfix and refinement release, addressing a number of issues
found in 1.2 final.
Furthermore, the PetClinic sample has been updated to serve as showcase for JMX export: the JDBC version exposes a cache refresh operation and a call monitor via JMX now.
We'd like to encourage all Spring 1.2 RC/final users to upgrade to Spring 1.2.1, in particular if using the Hibernate3 integration.
For complete details on changes and bug fixes, please see the change log.
FYI, a 1.2.2 release is scheduled for late June, introducing various minor new features. See our JIRA for details.
