Let's recap the last #NixOS release period from the Go perspective. There have been quite important changes to the Go ecosystem in nixpkgs, let's start with the one that will affect most users and maintainers of Go package:
buildGoModule now supports a self-referencing finalAttrs: parameter containing the final arguments including overrides. This allows packaging configuration to be overridden in a consistent manner by providing an alternative to rec {} syntax. This pattern will fix many issues people previously had overridden Go packages as it is adopted in nixpkgs. If you are maintaining a Go package, please check if you already updated it to use finalAttrs. The Go section of the manual has been updated for this and all examples now use finalAttrs.
