My friends, Spring Boot 3.1 is nearly upon us! It drops on 18 May, in just a few short days! There are a ton of amazing features in this new release and I hope you're already trying it out (you know where). Here are some of my favorite features:

• Built in Docker Compose support - Have a docker-compose.yml in your project root? Add spring-boot-docker-compose as developmentOnly scope in Gradle or optinal in Maven and Spring Boot will automatically run it for you on startup and shut it down on application shutdown. Here's an example
• Built in Testcontainers support - You know Spring Boot has first class support for Testcontainers in our unit testing framework. Perhaps you've used the @DynamicPropertySource mechanism to configure the environment based on Testcontainer containers? - but this new release makes things even better. Define a test-code only main(String []) method and then forward it to your production code main(String [] args) methods. You can point that test-code only main class to new @Configuration classes, which may in turn have Testcontainer connections defined. Run that test-code only main…

The single page was very large but often preferred for the ability to search with Ctrl+F. The multipage provided structure, but it was difficult to navigate and search. See for example the single and multiple versions from 4.3.x.

In 5.0 we switched to a single version that split the documentation into several high-level sections as a kind of middle ground between the single and the multipage versions. You could still use Ctrl+F within a section, while the content one any one of those pages wasn't as large as the full documentation. In this version we also added left-hand side navigation to make it easy to navigate the content. See example…
