Dear Spring community,

With Spring Framework 5.2.2 and 5.1.12 being available now, let me take the opportunity to provide an update on the maintenance roadmap in 2020.

Most importantly, Spring Framework 4.3.x and therefore Spring Framework 4 overall will reach its end-of-life next year: Our EOL cut-off is December 31st, 2020, with no further support on 4.3.x beyond that point. At the same time, we are also phasing out 5.0.x and 5.1.x for good.

As for planned releases, first up is a full round in mid January: with 5.2.3 and 5.1.13 accompanied by 5.0.16 and 4.3.26. The latter are the last…

On behalf of the team and everyone who has contributed, I am pleased to announce that Spring Framework 5.2.2 and 5.1.12 are available now.

The second maintenance release of the 5.2 line includes over 100 fixes and improvements. Spring Framework 5.1.12 includes 25 selected fixes and improvements.

As usual, we'll follow up shortly with corresponding Spring Boot releases (2.2.2 and 2.1.11).

See you early 2020 for a full round of Spring Framework releases, from 4.3.x up to the 5.2.x generation. More on that in a future blog post, stay tuned!

Hi, Spring fans! Can you believe - and I can't, by the way - that we're already in December 2019? The last month before the new year? The last month of this decade? It defies belief! I can't even imagine how we got this far so quickly, but it's great that we did. I started writing This Week in Spring in the first week of January 2011, so we're fast approaching 9 years of This Week in Spring!

As I write this I am in Toronto, Canada, for the last stop on the SpringOne Tour train for 2019. I enjoyed giving a two-hour talk introducing all sorts of stuff in the wide world of Reactive Spring…

This is the first in a series of blog posts in which we will look at how stream processing applications are written using Spring Cloud Stream and Kafka Streams.

The Spring Cloud Stream Horsham release (3.0.0) introduces several changes to the way applications can leverage Apache Kafka using the binders for Kafka and Kafka Streams. One of the major enhancements that this release brings to the table is first class support for writing apps by using a fully functional programming paradigm. This blog post gives an introduction to how this functional programming model can be used to develop stream…

Hi, Spring fans! In today's episode Josh Long (@starbuxman) talks to Spring Tools lead Martin Lippert (@martinlippert) about his time at Pivotal, and on the Spring team, his work on Spring Tools, and his work on language servers that now serve as the foundational integration for Spring users using Microsoft's Visual Studio Code, emacs and Atom, among other things.

Thanks, dear listener, and Happy Thanksgiving!

Dear Spring Community,

Today it’s my pleasure to announce General Availability of Spring Integration for Amazon Web Services extension version 2.3.0 and Spring Cloud Stream Binder for AWS Kinesis version 2.0.0.

These releases can be downloaded from Maven Central, JCenter, and our release repository:

compile "org.springframework.integration:spring-integration-aws:2.3.0.RELEASE"

If you don’t use Kinesis Binder. Or via Binder dependency:

compile "org.springframework.cloud:spring-cloud-stream-binder-kinesis:2.0.0.RELEASE"

Release Highlights

• The main theme of both these releases is about an integration testing using a Local Stack framework which helped us to spot several bugs and race conditions in both libraries.

• The spring-integration-aws provides a PutRecordsRequest (batch) support for KplMessageHandler collecting async results for UserRecords in that batch using Project Reactor Mono.fromFuture() functionality.

• A KinesisShardEndedEvent is now emitted from the KinesisMessageDrivenChannelAdapter when the next shard request returns null with the meaning that shard is closed and no records can be added to that any more.

• The spring-cloud-stream-binder-kinesis is based on the recently released Spring Cloud Stream version 3.0 and provides a new KinesisBinderHealthIndicator to check that all the streams involved in binding configurations are available.

We are pleased to announce the general availability of Spring Cloud Open Service Broker 3.1.0.RELEASE. Support for Open Service Broker API v2.15 is now feature complete. Thanks to the community for your feedback and contributions! This release includes all of the fixes and enhancements from the pre-release milestones:

• Upgrade to Spring Boot 2.2.1.RELEASE
• Add ServiceBrokerMaintenanceInfoConflictException to handle MaintenanceInfoConflict error scenarios
• ServiceBrokerInvalidParametersException now returns an HTTP 400 when a create or update request is malformed or includes invalid parameters. Previously it was, incorrectly, returning an HTTP 422.
• CreateServiceInstanceBindingRequest now extends AsyncParameterizedServiceInstanceRequest in order to utilize a common request object and reduce redundancy.
• Update reference documentation
• Support updating a Service Instance context
• Add list of endpoints…

Hi, Spring fans! Welcome to yet another installment of This Week in Spring! This week, I'm in Tokyo, Japan, for the Pivotal Summit Japan event. I've regretfully had to miss the China and Korea events because of a famly emergency, so it's nice to be able to make this, the last stop on the tour, before returning to California to celebrate Thanksgiving with the family.

And, on that note... it's almost Thanksgiving in the US. Thanksgiving is a time for us in the US to reflect on that for which we're thankful. I think I speak for the entire Spring team when I say that we are very grateful for you…
