 This is a parser for graphql, written to mirror the graphql-js reference implementation as closely while remaining idiomatic and easy to use.
 
-spec target: [October 2021](https://spec.graphql.org/October2021/) and [select portions of the Draft](https://spec.graphql.org/draft/), based on the graphql-js reference implementation [graphql-js v16.10.0](https://github.com/graphql/graphql-js/releases/tag/v16.10.0). This includes Schema definition language, block strings as descriptions, error paths & extension, etc. If there is a spec update or [new release](https://github.com/graphql/graphql-spec/releases), please follow this process to update and submit a PR.

 This parser is used by [gqlgen](https://github.com/99designs/gqlgen), and it should be reasonably stable.
