Runtime Briefing — Go 1.16 Embraces Modules and Embed

Go 1.16 landed on 16 February 2021 with module-aware mode enabled by default, a new embed package for bundling static assets, and native Apple silicon builds that platform engineers must incorporate into toolchains.

Executive briefing: The Go team published Go 1.16 on , closing the long transition to module-aware development, delivering first-party asset embedding, and widening platform support.

Feature highlights

  • Modules by default. The go command now uses module mode without the GO111MODULE flag, affecting dependency resolution for every build.
  • embed package. New directives let applications ship configuration files, templates, and Web assets within binaries without external pipelines.
  • Apple silicon builds. Official darwin/arm64 toolchains unlock native performance on M1 developer workstations and CI agents.
  • I/O and file system APIs. io/fs and testing additions expand virtual file system support for tooling.

Adoption steps

  • Audit repositories that still rely on GOPATH semantics and update CI scripts for module mode defaults.
  • Refactor asset packaging workflows to evaluate //go:embed usage and reduce runtime file dependencies.
  • Roll out native macOS ARM64 builds to unblock secure supply chains for developer laptops and managed runners.
  • Go 1.16
  • Modules
  • Runtime release
