v14.0.0

Thanks to all contributors for the hard work put into this release, which complies with the latest June 2018 version of the GraphQL Spec

Breaking:

• Drops support for node v4 and v9, makes sure node v10 is supported (#1338, #1445)
• Reject invalid scalar value coercion (#1365, #1336)
• Removes VariablesDefaultValueAllowed validation rule, and ProvidedNonNullArguments became ProvidedRequiredArguments (#1274)
• Stricter coercion of Scalar Types (#1382)
• Removes deprecated Introspection fields onOperation, onFragment, and onField (#1385, #1429)
• GraphQL*Config are now exact types (#1391, #1443)
• "Schema Change" keys in BreakingChangeType and DangerousChangeType for detecting adding args and input fields changed name (#1492)
• formatError API changed for error message extensions. To upgrade without changing existing server responses, wrap graphql's formatError:

import { formatError as baseFormatError, /* ... */ } from 'graphql';

{
  // other options
  formatError(error) {
    const { extensions, ...rest } = baseFormatError(error);
    return { ...extensions, ...rest };
  },
}

New:

• Parse new schema extensions (#1314, #1323)
• Export SDL AST types (#1315)
• extendSchema extended with spec-compliant SDL extensions (#1373, #1392, #1441)
• symbol.toStringTag support (#1297)
• Expose getOperationRootType(schema, operationAST) (#1345)
• Package is marked as side-effect free (#1312)
• validateSchema works with Schema extensions (#1410)
• validate works on SDL definitions (#1438, #1383)
• directives can be added to variable definitions, behind experimentalVariableDefinitionDirectives flag (#1437, #1454)
• ASTNode predicates, like isDefinitionNode and isTypeSystemDefinitionNode (#1459)
• isRequiredArgument and isRequiredInputField predicates (#1463)

Fixed:

• Fixes for custom enum types
• Prettier, Flow and eslint upgrades (#1304, #1319)
• Babel 7 upgrade (#1350)
• Introspection query perf improved (#1329)
• introspectionFromSchema has default options (#1408)
• buildSchema memory leaks and infinite recursion fixed (#1417, #1427)
• watch command fixed (#1449)

Deprecated:

These will be removed in v15

• getDescription, use the schema AST node to get descriptions (#1396)
• isValidJSValue, use coerceValue (#1386)

v0.13.2

New:

• Allow buildSchema() to take options (#1249)
• Update to Flow v0.68 (#1290)

Fixes:

• Update iterall (#1254)
• buildSchema: Make options optional (#1270)

v0.13.1

New:

• Publish .mjs files for module code to support native esmodules (#1244)
• Interface type definitions may now be extended with extendSchema (#1222)
• isValidNameError utility is now exported as a non-throwing alternative to assertValidName (#1237)
• ExectuableDefinitionNode Flow type is now exported (#1241)

Fixes:

• extendSchema now preserves (and allows extending) a list of legacy field names which would otherwise be considered invalid (#1235)
• Replaced a misplaced licensing header (7e68984)

v0.13.0

Breaking:

• Updated to latest spec for SDL for multiple interface implementations (#1169)

  To continue to support the pre-spec variation, use parse(text, {allowLegacySDLImplementsInterfaces: true})

• Internal module 'graphql/language/kinds' no longer directly exports enum values #1221

  Not that you were relying on internal modules, were you :)

New:

• getDescription helper function is now exported (#1165)
• Allows parsing pre-spec object type SDL with parse(text, {allowLegacySDLEmptyFields: true}) (#1171)
• Add introspectionFromSchema utility function (#1187)
• Add lexicographicSortSchema utility function (#1208) (#1220)
• Allow use of legacy names during schema validation with {allowedLegacyNames: ['__badName']} (#1194)

Fixed:

• Only trigger "one instance of graphql" error in DEV environments, removing false errors from minified bundles. (#1174)
• Fix 'astFromValue' to correctly handle integers and strings (#1181)
• Fix getTypeMap() not including input types used in directives (#1189)
• Support executeSync with mutations. (#1198)
• Fix block string printing edge cases (#1190, #1212)
• Fix SourceLocation incorrect export causing rollup bundling to fail (#1210)
• Preserve allowedLegacyNames when using extendSchema (#1226) (added since v0.13.0-rc.1)

• Excluded lock files from deployed npm package

v0.12.2

Fixes:

• Properly deploy a package on npm which contains es6-modules (#1161)

Flow Type Fixes:

• Removed experimental.const_params Flow option to ensure support for projects which do not enable this option (#1157, #1160)
• Changed visit() to return any instead of mixed to reduce the scope of the breaking change of adding Flow types for this function.
