⭐ [Go 1.27 Released](https://go.dev/blog/go1.27) — We spent much of the [previous issue](https://golangweekly.com/issues/614) anticipating this release, so we'll let it speak for itself, but 1.27 is now ready to go with the [final release notes](https://go.dev/doc/go1.27) and Jesús Espino's [Go 1.27 interactive tour](https://victoriametrics.com/blog/go-1-27/) covering the full details and practical updates respectively.

[Introducing Generic Methods](https://go.dev/blog/generic-methods) — A full explainer of the Go 1.27 feature that's caused the most excitement, at least in terms of _Go Weekly_ clicks! Concrete methods can now take type parameters, though interface methods still _cannot_, and Mark explains the reason why.
