The first major release of Java in 2024 is now available with the launch of Java 22.

Java 22 arrives six months after Java 21 and is an incremental feature update, not a Long-Term Support (LTS) release. With each new Java update, the community of developers led by 甲骨文 works on a series of Java Enhancement Proposals (JEPs) that are typically clustered under larger projects.
