v0.8.0

This release adds support for genqlient subscriptions; see the documentation for more, and thanks to @matthieu4294967296moineau for the original implementation and @HaraldNordgren for additional testing and improvements.

Note that genqlient now requires Go 1.22.5 or higher, and is tested through Go 1.23.3.

Breaking changes:

• genqlient now forbids omitempty: false (including implicit behaviour) when using pointer on non-null input field.
• The error text for HTTP errors has changed slightly. If you were parsing it, switch to As-ing to graphql.HTTPError.

New features:

• genqlient now supports subscriptions; the websocket protocol is by default graphql-transport-ws but can be set to another value.
  See the documentation for more details on how to use subscriptions.
• genqlient now supports double-star globs for schema and query files; see genqlient.yaml docs for more.
• genqlient now generates slices containing all enum values for each enum type.
• genqlient now returns Is/As-able errors when the HTTP request returns a non-200 status.

Bug fixes:

• omitempty validation:
  • allow omitempty on non-nullable input field, if the field has a default
  • allow omitempty: false on an input field, even when it is non-nullable
• don't do omitempty and pointer input types validation when use_struct_reference is used, as the generated type is often not compatible with validation logic.
• the allow_broken_features option, which no longer did anything, has been removed
