-`services.cloudflare-dyndns.apiTokenFile` now must be just your Cloudflare api token. Previously it was supposed to be a file of the form `CLOUDFLARE_API_TOKEN=...`.
- Emacs lisp build helpers, such as `emacs.pkgs.melpaBuild`, now enables `__structuredAttrs` by default.
Environment variables have to be passed via the `env` attribute.
-`buildGoModule` now passes environment variables via the `env` attribute. `CGO_ENABLED` should now be specified with `env.CGO_ENABLED` when passing to buildGoModule. Direct specification of `CGO_ENABLED` is now redirected by a compatibility layer with a warning, but will become an error in future releases.
Go-related environment variables previously shadowed by `buildGoModule` now results in errors when specified directly. Such variables include `GOOS` and `GOARCH`.
