On behalf of the team and everyone who has contributed, I am pleased to announce a new milestone for the next Spring Framework generation. The fifth milestone continues delivering new features and refinements on top of 7.0.0-M1, 7.0.0-M2, 7.0.0-M3 and 7.0.0-M4.

Jackson 3.0 support

As of #33798, we default to supporting Jackson 3.x in our entire stack, falling back to Jackson 2.x. Support for the Jackson 2.x generation has been deprecated in Spring Framework, and our current plan is to disable its auto-detection in 7.1, and remove its support entirely in 7.2.

Jackson 3.x uses a new tools.jackson package, which differs from the usual com.fasterxml.jackson. Classes from the "jackson-annotation" artifact (like @JsonView, @JsonTypeInfo) remain in the com.fasterxml.jackson…

It's a few months since we had a blog about Spring gRPC that wasn't just a release announcement. This one marks the first release since the project was promoted from experimental to a full member of the Spring Portfolio. This doesn't change the way you consume the project, but it has some implications for support and symbolically for what the project now means to the portfolio.

The latest release is 0.8.0, and it has been available for a couple of weeks now in Maven Central. The main reason for that release was to bump the dependencies to their latest versions, bringing Spring gRPC up to version 4 of the protobuf-java libraries. The easiest way to get started is to download a project with "gRPC" checked on the Spring Initializr. There are separate "starters" for Spring Boot applications gRPC that want to be "servers" or "clients", or you can get both at once from the plain spring-grpc-spring-boot-starter…

Hi, Spring fans! As I write this, I'm at the amazing Code Remix event in Miami (well, technically Tampa), Florida. I'll also be speaking at the Tampa JUG while I'm there, so look out! After that, I'll be headed back to Europe—a wee bit further north this time—to Stockholm for the amazing JForum event, where I'll be doing a much deeper dive into all things Spring.

You know what I'm most excited about? You don't have to look far to figure it out—just check out the ol' Spring Calendar. Spring AI releases on May 20th! And then, a few short and sweet days later—which, by the way, I'll be…

The Model Context Protocol (MCP) is a powerful feature in Spring AI that enables AI models to access external tools and resources through a standardized interface. One interesting capabilities of MCP is its ability to dynamically update available tools at runtime.

This blog post explores how Spring AI implements dynamic tool updates in MCP, providing flexibility and extensibility to AI-powered applications.

Understanding the Model Context Protocol

Before diving into dynamic tool updates, let's understand what MCP is and…
