Go 1.27 RC1 is out, try it in prod

Go 1.27 Release Candidate 1 is out, with the team asking people to run it against production load tests and file bugs against the release branch. Worth grabbing for the dev pipeline this week. On the proposal tracker, there's a request to add a MethodQuery constant to net/http to cover RFC 10008's safe, idempotent QUERY method. Elsewhere, a Zep engineer writes up why they moved their agent loop into Go after the usual Python and TypeScript suspects, which is a more interesting argument than the title suggests. And a familiar lament from the discussion threads: someone built a small rate limiter for a side project and discovered 5,000 requests from scattered IPs an hour after deploy, which is one way to learn that the logic was never the hard part.
