This Week in Spring - 28 November, 2023

Hi, Spring fans! I hope everyone who celebrated Thanksgiving had a wonderful time. Did you indulge in too much turkey? Anyway, let’s jump into this week’s edition of This Week in Spring—a particularly special one for a couple of reasons. First, it’s our first issue after the launch of Spring Boot 3.2 last Thursday. Second, it’s my inaugural post as a member of the Broadcom family. Exciting times!

Spring Boot 3.2: A Game Changer

Spring Boot 3.2 is nothing short of revolutionary. I’ve delved into its myriad features in an in-depth video, which you can watch here. This release includes:

• reactive cache/scheduled abstraction
• virtual threads (project Loom)
• CRaC
• improved GraalVM native image support
• Spring for Apache Pulsar support
• the new Spring Framework 6.1 RestClient and JdbcClient
• reloadable SSL
• Java 21
• observability
• spring.main.keep-alive=true
• Docker for Neo4J, ActiveMQ, etc.
• dependencies updates (of course)
• TransactionalExecutionListener

For those eager to try, head over to start.spring.io. Detailed release notes can be found for Spring Boot and Spring Framework.

Community Buzz

The response has been overwhelmingly positive. Paul Bakker from Netflix mentioned on Twitter that Netflix is gearing up to roll out Spring Boot 3.2 this week. Similarly, Michael Simmons tweeted about his seamless upgrade experience with a decade-old Spring Boot project.
