Using go fix to Modernize Go Code — Go 1.26 ships a rewritten go fix that automatically modernizes code to use newer idioms using 24 built-in 'modernizers': replacing interface{} with any, adopting strings.Cut, and so on. Alan goes into depth about how it works and what's coming next, including a self-service approach for defining your own modernizations.

🤖 What Should the Go Team Do with AI-Generated Contributions? — A discussion on golang-dev begun by Ian Lance Taylor when he noticed Claude as a co-author on a contribution. Responses from numerous Go heavyweights followed, including extensive thoughts from Russ Cox. Legal and licensing issues dominated the back and forth.

IN BRIEF:

The discussion around the proposal to add generic methods to Go has been long and thorough, but the proposal is now marked as 'likely accept' and has entered the 'final comment' stage.
The creator of a Node.js reverse shell tool ported it to Go and has shared benchmarks comparing the two versions. Go didn't lead in every metric, but was way out in front when it did.
There are fewer than two weeks to submit a proposal to GopherCon 2026 (closes March 4). Lightning talks will be accepted from June 1.

Proposal: Change Go 1.26's go mod init's Default Back to the Current Go Version? — New Go releases rarely contain unpleasant surprises, but some people aren't fans of Go 1.26's change to go mod init defaulting to a lower Go version in new go.mod files.

🔎 Inspecting the Source of Go Modules — The Go checksum database provides guarantees when you fetch through the toolchain, but browsing source elsewhere (on GitHub, or from a link on the Go package site, say) bypasses this. Filippo shows off his new Go modules source viewer site which provides an interface to view module sources directly from the Go modules mirror.
