TYPESCRIPT 6 HITS PKGSITE, GOLANG TOOLS SHED DEAD CODE

By RepoJournal · Filed 06:01 UTC on May 12, 2026 · About Go

The Go ecosystem's documentation and tooling infrastructure jumped a major version overnight, trading deprecated patterns for stdlib-native approaches.

golang/pkgsite shipped TypeScript 6.0 [2] alongside Jest 30 and a full ESLint modernization [3], clearing npm audit advisories and shedding the marked dependency in favor of a lightweight regex [1]. The TypeScript jump required deferring baseUrl deprecation cleanup to TS 7, a deliberate tradeoff to keep the upgrade clean. Meanwhile, golang/tools cut through its own technical debt by replacing xcontext.Detach with Go 1.21's native context.WithoutCancel [6], eliminating duplicate context logic across jsonrpc2_v2. gopls also deprecated the experimental importsSource option [7]—it's now just on by default—and tightened up its modernize analyzer to avoid suggesting unsafe rewrites when side effects lurk in the needle or predicate [8]. On the runtime side, ARM assembly got tighter [4] and VDSO test failures on ppc64le are fixed [5].

Action items

→ Review TypeScript 6 migration in pkgsite: baseUrl will require eventual cleanup in TS 7 golang/pkgsite [plan]
→ Upgrade to latest eslint and typescript-eslint in your local Go tools dev environment golang/tools [plan]
→ Test gopls completion behavior—importsSource option is now deprecated and ignored golang/tools [monitor]
→ Verify ARM code generation for AND with immediate operands in your CI golang/go [monitor]
