Welcome back to another installment of <EM>This Week in Spring</EM>! 
There's a lot to cover, so let's dive into it!

	<LI>  Always eager to help ring in the new year properly, Mark Fisher announced the <a href  = "http://blog.springsource.org/2012/01/09/spring-integration-2-1-is-now-ga/">Spring Integration 2.1 GA</a> yesterday.

Spring Integration 2.1 has been released! You can download it here or configure your Maven POM. This version is the result of more than one full year of work, and the team has resolved hundreds of issues since Spring Integration 2.0 was released. Interestingly, it has been 4 years and a few days since the very first public release of Spring Integration (0.5, released on Jan 3rd 2008). In this post, I simply want to provide a quick overview of the main new features of 2.1.

RabbitMQ/AMQP support

In the 'spring-integration-amqp' module, we have Channel Adapters for one-way messaging as well as Gateways for request/reply. The adapters and gateways can be used for inbound and/or outbound integration with a RabbitMQ broker. We also have AMQP-backed Message Channel implementations - both point-to-point and publish/subscribe - that can be used anywhere in the middle of a flow. For more information, see this section…

Happy new year! I hope your new year and holidays were amazing. And, welcome back to another installment of This Week in Spring.

This year is going to be <EM>incredible</EM>, so let's dive right into it.  



This week's  roundup features some content from the last few weeks. Particularly, we've got content that InfoQ   put up     
from the <a href = "http://www.springone2gx.com">SpringOne2GX 2011</a> conference.  

Thank you InfoQ for sharing this great content, as usual.

1. Garry Russel and David Turanski's SpringOne2GX presentation on implementing highly available architectures using Spring Integration is now up on InfoQ.

<LI> Rob Winch demoes some of the <A href = "http://www.infoq.com/presentations/Spring-Security-3-1">new features in Spring Security 3.1</a>: multiple http elements, stateless authentication mode for RESTful services, Debug Filter, CAS support for…

Today we're happy to announce that the Spring Framework has moved to GitHub!

As you've probably noticed, nearly every other Spring project has already made the move, and those that haven't will soon.

Git helps us with many of the challenges of managing a large codebase like the Spring Framework, but what's most exciting is what GitHub means for the Spring community. Many readers will already know the virtues of watching and forking repositories, pull requests, forking and editing, and the many other features that GitHub adds to the already excellent world of Git. If you're new to this stuff, be sure to check out the great materials at help.github.com…

Amidst the flurry of Spring releases this month, Spring Python has it's own.

Versions 1.1.1 and 1.2.1 are maintenance releases that patch some bugs. Version 1.3.0.RC1 is the first release of 1.3.0.

In this release we have commits from team members, and have also merged pull requests through github. If you want to make contributions to this project, don't forget to sign the contributor license agreement.

Thanks,

The Spring Python team

1. Santa's elves could learn a thing or two from the SpringSource engineers! Alan Stewart announced Spring Roo 1.2.0 GA on Saturday. This version of Roo has caught the attention of a lot of people. While there are many new features, some of my favorites are the multi-module Maven project support (which lets you, for example, build your model classes in a separate project from your web application), support JSF / PrimeFaces scaffolding (as opposed to just GWT, Spring MVC, Vaadin, and Flex), support for services / repositories (using Spring Data JPA and Spring Data MongoDB; this is in addition to the Active record style data-access objects…

It is my pleasure to announce that Spring Roo 1.2 GA has just been released. This release represents a significant amount of engineering effort by the Roo team and includes all the most popular features that the Roo user community have requested as well as many performance and usability improvements. The new features of Roo 1.2.0 are:

• Apache 2.0 licensed
• Multi-module Maven project support
• JSF / PrimeFaces scaffolding
• Services / repositories (using Spring Data JPA and Spring Data MongoDB)
• Database reverse engineering multi-schema support
• Flexible GWT support
• Shell usability improvements
