Reliably Absorbing a Go Release
summary
Kubernetes describes concrete steps for absorbing Go 1.21: start testing at Go HEAD (some tests run on the dev branch), identify and fix failures early, ensure changes pass both Go 1.n and Go 1.n+1, backport prerequisite fixes to release branches, and bump a release only after ~3 months of the Go release. Go 1.21 specifics used: go toolchain directive, preserved go debug flags for ≥2 years, and runtime metrics that count non-default Go behavior for observability.
