The Groovy development team is pleased to announce the release of Groovy 2.3.0!

Groovy 2.3 is the new major release of the Groovy programming language for the JVM, featuring:

• official support for running Groovy on JDK 8
• a new trait keyword to define new units of code for composing behaviors
• new and improved compile-time code transformations like:
  • @TailRecursive: for transforming methods with tail recursion to avoid blowing the stack,
  • @Builder: to easily implement fluent builders, generated by the Groovy compiler itself
  • @Sortable: to transform a class to implement Comparable using the various properties of the class
• a new NIO2 module with Path support
• lightening fast JSON parsing and building as covered in the recent article on InfoQ
• closure parameter type inference…

The Reactor team is pleased to announce that some significant updates to the Reactor framework are now available in the 1.1.0.RELEASE version of Reactor's flexible, asynchronous, fast data framework. This version includes numerous bug fixes and rewrites of key components to make them faster and, maybe more importantly, more efficient in terms of memory usage. Reactor 1.1 now includes the fantastic gs-collections library from Goldman Sachs [1] which provides a very fluent API for dealing with maps and collections of all kinds.

Here is a non-exhaustive list of changes between Reactor 1.0 and 1.…

We are happy to announce that Spring for Apache Hadoop version 2.0 RC3 has just been released.

Now includes support for the latest Hadoop distributions - Pivotal HD 2.0, Cloudera CDH5 and Hortonworks HDP 2.1

Other than version upgrades, the changes in this version revolve around partitioning support for writing datasets SHDP-327.

The main focus for Spring for Apache Hadoop 2.0 is to add YARN application development support in addition to continue to provide improvements in the HDFS and MapReduce support. You can see many of these new YARN features in use in the YARN samples and in the new Spring IO Guides…

Dear Spring community,

It's my pleasure to announce that Spring Framework 4.0.4 is now available. This is a straightforward maintenance release after 4.0.3, primarily fixing regressions and other recent bugs. It also comes with a range of minor dependency updates (including ASM 5.0.2).

http://projects.spring.io/spring-framework/

Aside from working towards our 4.1 release in July, we intend to do a 4.0.5 & 3.2.9 pair of releases in late May. Both of the latter are the last planned releases in the respective line. So if you have any critical bug reports to consider for those branches still…

Dear Spring Community,

I'm very happy to announce the general availability of Spring Social 1.1.0. Along with the release of the core Spring Social project, Spring Social Facebook 1.1.0, Spring Social Twitter 1.1.0, and Spring Social LinkedIn 1.0.0 are also now available.

These releases include several new features, including:

• Simplified Java and XML configuration support
• A new ReconnectFilter to automatically reestablish a connection when a token has expired or been revoked
• Updated API bindings for Facebook, Twitter, and LinkedIn
• A generic connection factory for APIs where there is not (yet) connection framework support
• Tighter Spring Security integration, including SocialAuthenticationFilter for provider-based sign-in
• Thymeleaf template support
• Updated documentation
• ...and much more...

Spring Boot 1.0.2.RELEASE is available now in the Spring and Maven Central repositories. This is mostly a bug-fix release (nothing major, but please upgrade if you are using an older version). There are also a couple of nice new features.

My favourite additions are the new @IntegrationTest features. Here's an example:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = SampleActuatorApplication.class)
@WebAppConfiguration
@IntegrationTest("server.port=0")
public class SampleActuatorApplicationTests {

	@Value("${local.server.port}")
	private int port…

Spring Security OAuth 2.0.0.RC1 is available now from the Spring Repo. This is a huge step in the direction of modernisation and ease of use for OAuth server and client apps on Spring.

The headline feature is support for @Configuration(for OAuth2 only) and if you use Spring Boot to write your app you can serve tokens and protect the API resources in about 25 lines of code:

@Configuration
@EnableAutoConfiguration
@EnableResourceServer
@RestController
public class Application {

	public static void main(String[] args) {
		SpringApplication.run(Application.class, args…

The Spring XD team is pleased to announce that Spring XD Milestone 6 is now available for download.

This is our biggest release yet! The team has been hard at work, and Milestone 6 contains a wealth of new features that meet enterprise requirements in terms of reliability, performance, and user experience. Below is a quick Top Ten (in no particular order), but if you checkout the release notes you will realize how difficult it is to pick out 10 from the list of 299.

• Distributed and Fault Tolerant Runtime: Leader election among multiple xd-admin servers and automatic redeployment of modules to other xd-containers in the case of failure. ZooKeeper is introduced to manage the cluster and its deployment state.

• Support for running XD on YARN: Run admin and container nodes on a Hadoop YARN cluster rather than on VMs or physical servers that you need to manage. There are simple configuration and shell scripts that make this process very easy.

• Deployment Manifests: When deploying a stream you can provide a deployment manifest that describes how to transform the logical stream definition (e.g. http | hdfs) to a physical deployment on the cluster. You can specify the number of instances of each module to deploy and also a criteria expression (using SpEL) that evaluates each of the available containers in the cluster to determine the best matches for those module instances. This will be an area of active development for the next release as we extend the manifest to include support for data partitioning strategies.
