To upgrade to the latest stable version of the Google provider run `terraform init -upgrade`. See the [Terraform website](https://www.terraform.io/docs/configuration/providers.html#provider-versions) for more information.
If you wish to work on the provider, you'll first need [Go](http://www.golang.org) installed on your machine (version 1.11+ is *required*). You'll also need to correctly setup a [GOPATH](http://golang.org/doc/code.html#GOPATH), as well as adding `$GOPATH/bin` to your `$PATH`.
In order to test the Google provider, see the [Tests section of the contribution guidelines](https://github.com/terraform-providers/terraform-provider-google/blob/master/.github/CONTRIBUTING.md#tests).
