- Official binaries now include the golang generated build ID `buildid` instead of an empty string. ([#101411](https://github.com/kubernetes/kubernetes/pull/101411), [@saschagrunert](https://github.com/saschagrunert))

- The go version defined in `.go-version` is now fetched when invoking test, build, and code generation targets if the current go version does not match it. Set $FORCE_HOST_GO=y while testing or building to skip this behavior, or set $GO_VERSION to override the selected go version.

## Changelog since v1.17.4

## Changes by Kind

### Feature

- deps: Update to Golang 1.13.9
  - build: Remove kube-cross image building ([#89399](https://github.com/kubernetes/kubernetes/pull/89399), [@justaugustus](https://github.com/justaugustus)) [SIG Release, Storage and Testing]

### Bug or Regression

- Build/lib/release: Explicitly use '--platform' in building server images
  
  When we switched to go-runner for building the apiserver,
  controller-manager, and scheduler server components, we no longer
  reference the individual architectures in the image names, specifically

- Official support to build kubernetes with docker-machine / remote docker is removed. This change does not affect building kubernetes with docker locally.

unnecessary redirection from ci/latest.txt to ci-cross/latest.txt. Users should know exactly where the builds are stored on Google Cloud storage buckets from now on. For example for 1.9 and 1.10, users can specify ci/latest-1.9 and ci/latest-1.10 as the CI build jobs what build images correctly updates those. The CI jobs for master update the ci-cross/latest location, so if you are looking for latest master builds, then the correct parameter to use would be ci-cross/latest.
