(2007/11/19) - We're pleased to announce that Spring Framework 2.5 has been released. Here is Juergen's original announcement:
Dear Spring Community,
We are pleased to announce that the Spring Framework 2.5 final release is now available.
Spring 2.5 enhances Spring 2.0 with many exciting new features, including:
Check out the series What's New in Spring 2.5? for a walkthrough of the new Spring 2.5 features, including information on how to deploy the Spring sample applications that demonstrate them.
- Full Java 6 and Java EE 5 support (JDBC 4.0, JTA 1.1, JavaMail 1.4, JAX-WS 2.0)
- Full-featured annotation-driven dependency injection, including support for 'qualifiers'
- Support for auto-detecting application components in the classpath and auto-configuring them as Spring managed objects
- A new bean name pointcut element in AspectJ pointcut expressions
- Built-in support for AspectJ load-time weaving based on the LoadTimeWeaver abstraction
- New XML configuration namespaces "context" and "jms", for maximum convenience
- A completely revised integration test framework, with first-class support for JUnit 4 and TestNG
- A new annotation-based controller model for Spring MVC supporting Servlet and Portlet environments
- Extended SimpleJdbcTemplate functionality, including support for named SQL parameters
- Officially certified WebSphere support
- The packaging of Spring Framework jars as OSGi-compliant bundles out of the box
- The ability to deploy a Spring ApplicationContext as a JCA RAR file, for headless application modules
- JCA 1.5 message endpoint management, for Spring-managed JMS and CCI message listeners
We recommend upgrading to Spring 2.5 from all previous Spring 2.0.x versions in order to benefit from the new features as well as the significant performance enhancements that Spring 2.5 has to offer. Spring 2.5 is designed as a drop-in replacement for Spring 2.0, except for the slightly restructured jar file contents (please see the readme file in the distribution for more information on this).
Please note that Spring 2.5 is still compatible with JDK 1.4.2+ and J2EE 1.3+. Java 1.4 users, for example on WebLogic 8.1 or WebSphere 5.1/6.0, are very welcome to upgrade to Spring 2.5 as well. We recommend putting the backport-util-concurrent jar on the classpath when running on Java 1.4, which allows Spring and your applications to benefit from significant concurrency enhancements.
Enjoy Spring 2.5,
Lead, Spring Framework Development
