• Do not throw client safe Error when failing to serialize an Enum type
• Use native PHP types for properties of Type and its subclasses

• Move debug entries in errors under extensions key
• Use native PHP types wherever possible
• Always throw RequestError with useful message when clients provide an invalid JSON body

• Exclude unused standard types from the schema
• Require lazy type loader to return Type directly without an intermediary callable
• Allow lazy type loader to return null
• Rename ServerConfig option persistentQueryLoader to persistedQueryLoader
• Call previously unused methods EnumType::parseValue() and EnumType::parseLiteral()
• Strongly type PromiseAdapter::createRejected() to require \Throwable
• Move members specific to NamedType out of Type: $name, $description, $config, isBuiltInType(), assertValid()
• Always convert recursively when calling Node::toArray()
• Make Directive::$config['args'] use the same definition style as FieldDefinition::$config['args']
• Rename FieldArgument to Argument
• Make errors when parsing scalar literals more precise
• Change expected QueryPlan options from ['group-implementor-fields'] to ['groupImplementorFields' => true] in ResolveInfo::lookAhead()

• Use JSON_THROW_ON_ERROR in json_encode()
• Validate some internal invariants through assert()
• PromiseAdapter::all() accepts iterable
• Throw if Introspection::fromSchema() returns no data
• Reorganize abstract class ASTValidationContext to interface ValidationContext

• Order schema topologically and according to the user-defined order, affects introspection and printing
• GraphQL\Utils\AST::typeFromAST() now needs a type loader callable instead of the Schema
