Hugo `0.48` is built with the brand new Go 1.11. On the technical side this means that Hugo now uses [Go Modules](https://github.com/golang/go/wiki/Modules) for the build. The big new functional thing in Go 1.11 for Hugo is added support for [variable overwrites](https://github.com/golang/go/issues/10608). This means that you can now do:
The above may look obvious, but has not been possible until now. In Hugo we have had `.Scratch` as a workaround for this, but Go 1.11 will help clean up a lot of templates.
