Welcome to another installment of This Week in Spring! This week, as is our tradition, we'll look back at a few of the big things that made 2014 a wonderful year to be a Spring developer. And, what a year it was!

• The tail end of last year saw Spring 4 GA and this year saw the Spring 4.1 release just shy of 9 short months after 4.0! Spring 4.x boasts a dizzying array of new features! Java 8 support, Java EE 7 support, new Spring MVC views, JSR 107 support, a powerful resource pipeline and the @Conditional annotation which of course made possible...
• Spring Boot, whose first 1.0 GA was in April of this year, has seen two epic updates (1.1, and 1.2) since then. Spring Boot's taken the community by storm, spawning all sorts of activity both from our team and, more importantly, from everybody else! The competition have attempted to downplay it, or copy it. Existing Spring users have flocked to it in droves (including the likes of Netflix and Ticketmaster). If you follow this weekly roundup, though, then you need no further evidence of the community's uptake! It's been so much fun watching people blog…

On behalf of the Spring XD team, I am very pleased to announce the second milestone release of Spring XD 1.1 and the 1.0.3 maintenance release.

Download Links:

• 1.1.0.M2 RELEASE: zip, 1.0.3.RELEASE: zip

The 1.1 M2 release includes bug fixes and enhancements as well as several new features:

• Kafka based Message Bus. If Kafka is your middleware du jour, you will feel right at home.
• Batching and compression support for RabbitMQ provides significantly increased effective message rate throughput.
• Develop Processor modules using Project Reactor’s Stream API. The Stream API is based on the Reactive Streams specification that provides a standard for asynchronous stream processing with non-blocking backpressure. This allows you to use a functional programming model as the basis for processing event streams. Combined with XD’s support for Data Partitioning on the Message Bus…

Another cheerful holiday message from the Spring team: Spring Cloud 1.0.0.RC1 is now available in the http://repo.spring.io Maven repository. There are plenty of new features including

• Support for Hystrix metrics aggregation via an annotation @EnableTurbine and @EnableTurbineAmqp (for an AMQP-based collector)

• A rehaul of the Ribbon configuration making it more friendly for Spring users. You can now configure each Ribbon client in its own ApplicationContext using @RibbonClient and override various bits, like the LoadBalancer, or the ServerListFilter, by providing @Bean definitions.

• DiscoveryHealthIndicator is now a composite that users can add information to by declaring @Beans of type DiscoveryHealthIndicator.

• Discovery is now abstracted away from Eureka into a new spring-cloud-commons library, and enabled via new annotations like @EnableDiscoveryClient (instead of the old @EnableEurekaClient). The same pattern also applies to circuit breakers

We are pleased to announce the third milestone release of Spring for Apache Hadoop 2.1. The release is now available in the Spring IO repository

We have worked on improving the YARN and data store writers. There are also new @Configuration changes and improvements to the Boot auto configuration features. See the full changelog for more details.

Beginning with the Spring for Apache Hadoop 2.1 version, we now only support Hadoop 2.0 APIs and no longer provide backwards compatibility with older Hadoop v1 distributions. If you need support for older Hadoop versions please use the 2.0.4 or 1.1.…

Welcome to another installment of This Week in Spring! In a few short weeks we'll be in 2015! Will that be exciting? Of course. But this week's pretty exciting as well! So much good stuff this week.

• Spring Boot 1.2.0 is here! So many new features for Java EE (Servlet 3.1-baseline, JTA, JMS and JNDI support) and improved Jackson output, Actuator endpoints, CLI updates and performance. Spring Cloud is already tracking 1.2 and will be based on this soon, as well. Get the bits.

• Spring Boot 1.1.10 is now available with numerous fixes.

• Resident mad-scientist Andy Wilkinson just announced the latest cut of the Spring IO platform library. There are lots of things of note, but in particular it's added support for Spring Integration Flow 1.0, Spring Integration Java DSL 1.0, and Spring Integration Splunk 1.1 and updated revisions for several projects besides.

Spring Security OAuth 2.0.5.RELEASE is available now in all the usual Maven repositories. This is a bugfix release but nothing critical. We recommend upgrading if you are having trouble with customizing the Java config, since most of the issues resolved relate to that (for instance it is much easier to customize the password encoder for client secrets). There is a small breaking change for anyone using the AuthorizationServerEndpointsConfigurer directly to configure a ClientDetailsService (it doesn't work that way, so you would be failing to configure it anyway).

For a range of samples using and displaying all the features of Spring Security OAuth please look in the github project (e.g. at the integration tests or the samples…
