Spring Boot 3.2 is the first to support Java 21 virtual threads (also known as Project Loom) products, Java 21 virtual threads will have a significant impact on their performance and efficiency. According to VMWare developer advocate Josh Long, prior to Java 21, each new thread used 2MB of RAM, and virtual threads were lightweight.

This version also supports localized compilation using Spring Boot and GraalVM's virtual threads, greatly reducing startup time

Another new feature is SSL hot reloading. This feature enables embedded web servers, specifically Tomcat and Netty, to update SSL certificates without restarting. Once a new certificate is installed, already established connections will continue to use the old certificate, while new connections will be secured with the new certificate

This book contains a sample project that avoids unnecessary EJB (Enterprise JavaBeans) usage and evolves it into the Spring framework.

Command: Spring boot add AI will add libraries to existing projects to support artificial intelligence functions such as chatbots.
