Understand it, then run it

The Go 1.27 release candidate 3 was published. This is a standard release cycle event: a new candidate version is made available for testing before the final 1.27 release. No new language features or API changes are introduced in this candidate. The main impact is that developers can run their code against the candidate to catch any regressions.
