This release contains a number of fixes and enhancements.

GraphQL Built-in Functions

A new set of built-in functions are now available to validate, parse and verify GraphQL query and schema! Following are
the new built-ins:

graphql.is_valid: Checks that a GraphQL query is valid against a given schema
graphql.parse: Returns AST objects for a given GraphQL query and schema
graphql.parse_and_verify: Returns a boolean indicating success or failure alongside the parsed ASTs for a given GraphQL query and schema
graphql.parse_query: Returns an AST object for a GraphQL query
graphql.parse_schema: Returns an AST object for a GraphQL schema

Built-in Function Metadata

Built-in function declarations now support additional metadata to specify name and description for function arguments
and return values. The metadata can be programmatically consumed by external tools such as IDE plugins. The built-in
function documentation is created using the new built-in function metadata.
Check out the new look of the Built-In Reference
page!

Under the hood, a new file called builtins_metadata.json is generated via make generate which can be consumed by
external tools.
