The Spring Boot team released Spring Boot 3.2 in November 2023. This latest release is packed with features, the most noteworthy of which is the support for virtual threads and Coordinated Restore at Checkpoint (CRaC). Other features include SSL-bundle reloading, support for the RestClient and JdbcClient interfaces, and observability improvements.
In JDK 21, a particularly significant feature is Project Loom’s virtual threads, which the JEP describes as lightweight threads that dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications.
