Go 1.27 lands with generic methods, encoding/json/v2, and a uuid package

Go 1.27.0 is out, and the headline features are chunky: generic methods, an encoding/json/v2 package, a standard library uuid package, faster memory allocation, and goroutine leak profiles. Off to one side, a proposal to add text/markdown based on rsc.io/markdown is now in play, which would give the standard library a first-class Markdown parser to match. Elsewhere, a writeup on the new simd and simd/archsimd packages claims a 7.5x speedup for ChaCha20, which is a decent early field report on what 1.27 actually unlocks.
