JDK 22 will be released on March 19th 2024 but it’s forked today (Dec 7th 2023) and so its feature set is final: It finalizes unnamed patterns and variables, G1 region pinning, the FFM API, and multi-source-file programs. On top of that it previews/incubates the simpler main method, string templates, the vector and class-file APIs, structured concurrency and scoped values, statements before this(...) and super(...), and stream gatherers.
