On behalf of the community, I am pleased to announce the General Availability of the Spring Cloud 2021.0 Release Train, codename Jubilee, is available today. The release can be found in Maven Central. You can check out the 2021.0 release notes for more information.

Notable Changes in the 2021.0 Release Train

2021.0.0 is compatible with Spring Boot 2.6.1

See the project page for all the issues and pull requests included in this release.

Spring Cloud Commons

• Support for per LoadBalancer configuration properties (added as well to Gateway, Contract and OpenFeign).

Spring Cloud 2021.0.0 is finally out and with it you have Spring Cloud Function 3.2

While the full list of features, enhancements and bug fixes is available here, I’d like to call out few of them in this post and provide some details.

gRPC Support

In addition to an already existing support for invoking function via AWS Lambda, RSocket, Spring Cloud Stream etc., Spring Cloud Function now allows you to invoke function via gRPC.
Two ways to benefit from it.

Spring Message

Given the wide adaption of Spring Messaging, one way of benefiting from gRPC support is by embracing Spring’s Message.
Spring Cloud Function provides GrpcSpringMessage schema modeled after Spring’s Message. It is internally converted to Spring Message to benefit from all of the existing support for Spring Messaging.

Hi, Spring fans! I love the Azure Spring Cloud platform - jointly developed with the Spring team and Microsoft - and I’m not alone! So do its users! Check out this panel discussion moderated by Adib Sakali and Asir Selvasingh with Morgan Stanley, Bosch, and Digital Realty Trust.

Hi, Spring fans! In this installment of Spring Tips (@SpringTipsLive), we continue our tour of all things @Controller, this time focusing on the Spring support for RSocket. You might also want to watch the expanded discussion of RSocket in earlier Spring Tips videos:

Hi, Spring fans! Welcome to another installment of This Week in Spring! This last week’s been nutty! Here in the US, we just celebrated the Thanksgiving holiday, and I am fat with turkey and pie, and lazy. But happy. I hope you’re well fed and happy, too. Time’s flying. (Also: can you believe we’re a month away from the new year? I think there’s like four or five weeks (and thus _This Week in Spring_s!) left in the year!)

We’ve got a ton of stuff to get into this week, so let’s go:

• Security Report for Spring AMQP (Spring for RabbitMQ)
• Spring Boot 2.6.1 is now available
• Spring Data MongoDB - Relation Modelling
• Thymeleaf 3.0.13 now available! This new version includes security improvements, make sure to check the release notes
• In last week’s installmetn of A Bootiful Podcast, I talked about reactive-systems with functional programming legend Debasish Ghosh
• The Apache Cassandra project is working hard to officially support JDK 17 in the next Apache Cassandra major release.
• I love to see how far the JVM has come. One great indicator of its progress: its garbage collector. Check out this post on garbage collection progress from JDK 8 to JDK 17
• This is so cool! There’s now an Oracle Database Kubernetes Operator
• JEP 420: Pattern Matching for switch (Second Preview)
• Java on Visual Studio Code Update – October 2021
• For a lot of folks, the days of using Docker Desktop for free are numbered. You might be interested in this blog on Rancher Desktop - A Docker Desktop Replacement
