Spring Cloud Commons

• The bootstrap phase is no longer enabled by default. If your project requires it, it can be re-enabled by properties or by a new starter. To re-enable by properties set spring.cloud.bootstrap.enabled=true or spring.config.use-legacy-processing=true. These need to be set as an environment variable, java system property or a command line argument. The other option is to include the new spring-cloud-starter-bootstrap. Bootstrap is mostly used to import configuration from remote sources. To do this without boostrap see the new features in Config, Consul, Vault and Zookeeper.

• Added a mechanism to avoid retrying on the same instance

With the recent release of Spring Security 5.4, we’d like to announce that maintenance for Spring Security SAML Extensions 1.x will end on 6 October 2021.

SAML 2.0 support has been added to the core Spring Security framework over the last three minor releases. There are two main reasons for this.

First, the extension project is based on a version of OpenSAML that the OpenSAML team no longer supports. This version has known CVEs that make it unsafe for use in a production system.

Second, moving the support to the core Spring Security framework allowed us to simplify the API, use the latest OpenSAML, and add long-requested support for features like multi-tenancy and Spring Boot integration…

On behalf of the Spring and Apache Geode communities, it is my pleasure to announce the release of Spring Boot for Apache Geode (SBDG) 1.1.10.RELEASE, 1.2.10.RELEASE, 1.3.4.RELEASE and 1.4.0-M3.

SBDG 1.1.10.RELEASE is based on Spring Boot 2.1.17.RELEASE, SBDG 1.2.10.RELEASE is based on Spring Boot 2.2.10.RELEASE, SBDG 1.3.4.RELEASE is based on Spring Boot 2.3.4.RELEASE and SBDG 1.4.0-M3 is based on Spring Boot 2.4.0-M3. In addition, SBDG pulls in the latest Spring Data, Spring Session and Spring Test for Apache Geode releases and bits.

Each of these releases includes dependency alignment, documentation revisions and minor improvements. See the changelog…

On behalf of the Spring and Apache Geode communities, it is my pleasure to announce the release of Spring Session for Apache Geode (SSDG) 2.1.11.RELEASE, 2.2.5.RELEASE, 2.3.1.RELEASE and 2.4.0-RC1.

SSDG 2.1.11.RELEASE is pulled in by Spring Boot 2.1, SSDG 2.2.5.RELEASE by Spring Boot 2.2, SSDG 2.3.1.RELEASE by Spring Boot 2.3 and SSDG 2.4.0-RC1 by Spring Boot 2.4. All of these releases are primarily dependency alignment releases and pick up the latest Spring Data bits on which SSDG is strongly based.

Note

SSDG 2.4.0-RC1 is now based on Apache Geode 1.13.0. Given VMware Tanzu GemFire (formerly known as Pivotal GemFire) is now longer released by VMware, Inc. as a standalone, independently managed solution, SSDG 2.4 will no longer ship a spring-session-data-gemfire module. GemFire 9.10 was the last supported, standalone, independently managed version of GemFire, which was based on Apache Geode 1.12…

What’s New?

This release comes with a number of new features that you can find in the release notes, but here are the major highlights:

1. GraalVM Support

A lot of work has already been done in Spring Framework to support running some types of Spring applications on GraalVM. In this release, we made changes in Spring Batch to correctly run Batch applications on GraalVM as well.

The support is still experimental, so we encourage you to give the release a try and share your feedback.
