The HashiCorp Terraform Registry is being updated to include all Terraform providers, both maintained by HashiCorp and community providers, allowing for automatic download and installation of providers published in the Registry. The configuration language is also getting an update to support this change, with new syntax that allows authors to host and publish providers to the Registry from their own GitHub repositories. This change aims to simplify provider use, offering streamlined access to partner and community providers while providing clear links to ownership. Terraform will continue to automatically download HashiCorp's providers, but users can now declare a registry source for any provider, enabling simplified installation of providers not listed in the public registry.
