New features include: JEP 516 (Ahead-of-Time Object Caching with Any GC, extending AoT cache to ZGC via a GC-agnostic format), JEP 522 (G1 GC throughput improvements via a dual card table approach reducing synchronization, yielding 5-15% gains), and JEP 517 (HTTP/3 support in the HTTP Client API with four protocol negotiation strategies). Re-previewed features include PEM Encodings of Cryptographic Objects (2nd preview), Structured Concurrency (6th preview), Lazy Constants formerly known as Stable Values (2nd preview, with major API renames), Vector API (11th incubator, unchanged), and Primitive Types in Patterns/instanceof/switch (4th preview). Deprecations include JEP 500 (preparing to restrict mutation of final fields via reflection) and removal of the Applet API. ## Full article daily.dev links to this article rather than hosting it.
