What changed in Go 1.27 (released August 2026) and how it changes the way Go is written in pi-go. Use this skill when writing or reviewing Go that could use a 1.27 feature, when bumping the `go` directive in go.mod, when a build or test behaves differently after a toolchain upgrade, or when `code-guidelines-go` points here. Covers generic methods, struct-literal field selectors, generalized type inference, the go command and go fix changes, the size-specialized allocator, the `goroutineleak`…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Go 1.27 — What Changed and What To Do About It **Released**: August 2026, six months after Go 1.26. Go 1 compatibility holds; almost all programs compile and run unchanged. **Sources**: [go.dev/doc/go1.27](https://go.dev/doc/go1.27) (authoritative) · [victoriametrics.com/blog/go-1-27](https://victoriametrics.com/blog/go-1-27/) (worked examples). Every claim below is from one of those two, or from reading `$(go env GOROOT)/src` on the installed 1.27.0 toolchain. Companion skill: `code-guidelines-go` holds the standing style rules. This skill holds only what 1.27 *changed*. --- ## 0. Read this first — `GOEXPERIMENT=none` is set on this machine `go env` on this host persists `GOEXPERIMENT=none`, which does **not** mean "no extra experiments" — it clears the 1.27 *baseline*, which enables `JSONv2`, `GreenTeaGC`, `SizeSpecializedMalloc`, `Dwarf5` and `RandomizedHeapBase64` (`src/internal/buildcfg/exp.go:81`). Verified consequences here: ``` $ go build ./... # importing encoding/json/v2 imports encoding/json/v2: build constraints exclude all Go files in .../encoding/json/v2 $ golangci-lint --version …

How to install
mdr add dimetron/pi-go/go-127@sha256:ea953276bf677cdfThe line at the top of this page pins the label git:20260919.7d49ee6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
