Spring Integration 5.5 M3 & 5.4.5 Available

Releases | Artem Bilan | March 18, 2021 | ...

Dear Spring community,

On behalf the team and external contributors, it’s my pleasure to announce a Milestone 3 release for Spring Integration 5.5, plus Spring Integration 5.4.5 patch version.

The latest one can be downloaded from Maven Central:

compile 'org.springframework.integration:spring-integration-core:5.4.5'

and it is recommended to upgrade your projects or just pull it transitively from just released Spring Boot 2.4.4!

The Milestone is available from the repository:

compile 'org.springframework.integration:spring-integration-core:5.5.0-M3'

The 5.5 generation of Spring Integration is the last one in the line before we start 6.0 and it is mostly based on the community feedback and usability needs. For example we have reworked some warning messages in logs to the fail-fast errors during configuration phase. Plus some API was deprecated with possible removal in the next major version. So, be sure check the Migration Guide

Engineering | Josh Long | March 18, 2021 | ...

NOTE: this post was written by our friend Kylie Liang (@liangkylie) from the Microsoft Azure Spring Cloud team. Thanks, Kylie!

We are excited to announce the general availability of the Azure Spring Cloud Managed Virtual Network and Autoscale features. Both are critical to securely running production workloads at scale on the Azure Spring Cloud service.

Secure Azure Spring Cloud in Managed Virtual Network

With the Managed Virtual Network feature, you can provision the Azure Spring Cloud service in your virtual network which enables:

  • Isolation of Azure Spring Cloud apps and service runtime from the internet on your corporate network.
  • Interacting with systems in on-premises data centers or Azure services in other virtual networks.
  • Controlling inbound and outbound network communications for Azure Spring Cloud.

Spring Cloud AWS 2.3 is now available

Releases | Spencer Gibb | March 17, 2021 | ...

The following is a guest post from the maintainers of the Spring Cloud AWS project.

On behalf of the Spring Cloud AWS team and the community around Spring Cloud AWS, I am happy to share that we have just released Spring Spring Cloud AWS 2.3 - a version that is compatible with Spring Boot 2.4 and Spring Cloud 2020.0.

This release contains a new integration with Cognito and a bunch of small improvements, fixes, and changes that we believe will make working with Spring Cloud AWS more pleasurable.

I believe the most surprising change is that now you need to include a separate Spring Cloud AWS BOM in your pom.xml
