Go 1.27 lands generic methods, a faster JSON v2, and post-quantum ML-DSA
Go 1.27 ships long-requested generic methods plus native UUID support and faster, stricter encoding/json/v2. Toolchain and runtime gains include generic function type inference, ~30% cheaper small-object allocation, a generally available goroutine-leak profiler, and production-grade ML-DSA post-quantum signatures baked into TLS and x509.
