Hi, Spring fans! Welcome to another installment of This Week in Spring! I write this having spent a wonderful week in paradise (Bora Bora, French Polynesia, to be precise) with my partner Tam Mie. We were so very sad to have to say goodbye.

But that means I'm officially back at my desk, with nary a manta ray to be found anywhere. Sigh. That's okay, though, as there are a ton of amazing things to read and catch up on - so let's dive into this week's roundup (if not the pearly blue, crystal-clear oceans of the South Pacific)!

• Good news, everybody! Spring gRPC 0.9.0 is available now!
• In last week's installment of A Bootiful Podcast, I talked to the legendary Dr. Heinz Kabutz.
• Andres Almiray did a follow-up blog to our post introducing Spring AI and Oracle DB as a vector store back in May—this one on connecting Spring AI to Oracle Autonomous DB.
• A nice blog post looking at what's new in Spring Boot 4.0.
• Come watch AWS developer advocate and industry legend James Ward, and yours truly, as we explore AI with Spring AI and Amazon Bedrock.
• JUnit 6.0.0.M1 is available for, erm, testing!
• Spring Modulith lead Oliver Drotbohm looks at the overhauled event publication registry support in Spring Modulith 2.0…

On behalf of the team and everyone who has contributed, I'm happy to announce that Spring gRPC 0.9.0 has been released and is now available from Maven Central. We are still planning to have a 1.0.0 release around the same time as Spring Boot 4.0.0.

The main changes in this release are

• Upgrade to Spring Boot 3.5.
• StubFactory contract changes: the "supports" method is now a static method (it is called before an instance is created).
• Removed GrpcClientFactoryCustomizer in favour of GrpcChannelBuilderCustomizer.
• Added ability to filter interceptors in in-process gRPC clients.
• Added ability to filter global interceptors and service definitions - easy to do for InProcessGrpcServer and possible to do for NettyGrpcServer by registering a customizer.
