v0.4.0

🚀 Features

• Federation 2 Support - EverlastingBugstopper, pull/887

  The alpha version of Federation 2 has been released!

  In Rover, you can use the Federation 2 composition model by running rover fed2 supergraph compose --config <supergraph.yaml> after installing the rover-fed2 binary.. You must install rover-fed2 before you can run rover fed2 supergraph compose, and they must be the same version in order to be compatible with each other.

• Graph lifecycle management - EverlastingBugstopper, issue/722 pull/861

  Rover now supports the rover graph delete command, which will delete all subgraphs in a federated variant, or delete the schema for a non-federated variant.

  There is also new documentation on how rover graph publish and rover subgraph publish create new variants.

  Additionally, you no longer need to pass --convert to subgraph publish when publishing a subgraph to a new variant, though you will still need it when converting a non-federated variant to a federated variant.

• Fetch the subgraph's routing_url from the graph registry if it isn't specified in a supergraph.yaml file - EverlastingBugstopper, pull/873

  Now, whenever routing_url is not specified for a subgraph in supergraph.yaml and the source is a graphref (which fetches a subgraph from the graph registry), the composed supergraph will use the routing URL from the graph registry for that subgraph instead of an empty string.

🐛 Fixes

• Output enum descriptions in introspection results - lrlna, issue/878 pull/879

  Now, any introspection result that contains descriptions for enums will include them in the output.

• Output directive arguments in introspection results - lrlna, pull/858

  Now, any introspection results that contain directive arguments will include them in the output.

🛠 Maintenance

• Refactor HTTP client configuration - ptondereau, issue/844 pull/890

  When Rover first introduced options to configure the HTTP client, there was a function that took configuration arguments, and returned a client. This has now been refactored to use a more idiomatic builder approach. Thanks @ptondereau!
