summary

Java 21 packages concrete language and runtime changes: pattern matching for switch and record patterns add exhaustiveness and deconstruction, sequence collections add reversed/first/last access, and string templates enter preview. Project Loom delivers virtual threads finalized with structured concurrency and scoped values in preview, and ZGC becomes generational. AppCDS startup archives, a simple web server, and vector/foreign APIs remain incubating. Windows x86 32-bit is deprecated for removal; most features aim to reduce boilerplate and improve latency and startup.
