v0.4.18

New:

• Adds validator to ensure variable names are unique (#296)

v0.4.17

Fixes:

• Fix a case where the AST printer could erroneously exclude information from anonymous operations (#289)

v0.4.16

New:

• Utilities for comparing GraphQL types are now exported directly. (aff18e6)

Fixes:

• No longer parses documents which contain u2028 or u2029 characters, to comply with the spec. This is technically breaking, but these are so rare that I doubt anyone will encounter this.

v0.4.15

New:

• The full GraphQL API is now exported from the top module. If you're building a tool that uses GraphQL.js, hopefully this makes it easier to import and use utilities in this library. (4547904)
• Clearer error messages:
  • When a requested field cannot be found on an interface or union, we'll suggest an inline fragment. (#282)
  • When a variable isn't used, we'll include the name of the query that defined it.
  • When a field typed as List returns something that is not a list, the error will include the name of the type and field. (#276)
  • When an input type includes unknown information, ensure it's name is printed. (#261)

v0.4.14

New:

• Original errors can now be retrieved from any GraphQLError with error.originalError #251.
• visitWithTypeInfo now supports visitors which edit or break-early.
• visitInParallel now experimentally supports visitors which edit or break-early.

Fixes:

• No longer allows 52-bit integers, instead requiring 32-bit values as per the spec.
• No more false-positive validation errors when validating a query which contains experimental type definitions #255.
• visitInParallel now correctly skips subtrees when a visitor returns false #254.
• Release now uses babel-runtime again, broken in 0.4.13, #246.

v0.4.13

New:

• import { extendSchema } from 'graphql/utilities allows extending an existing schema with the GraphQL type definition language (#227)
• When an Object type implements an Interface type, a field on the Object type can return a more specific type than the same field defined on the Interface type. This "covariant return types" is now also defined in the GraphQL Spec (#239)
• Loosens the rule which requires overlapping fields to be unambiguously merged in the case that two same-named fields are statically known to not overlap due to being conditional to different types. This rule change has also been reflected in the GraphQL Spec (#229)
• Removes the rule which requires overlapping fields to have equivalent directives. This rule change has also been reflected in the GraphQL Spec (#230)
• Validation now ~25-30x faster due to a number of improvements including simplifications, algorithm improvements, memoization, and running validation rules in parallel.
  • Parallelizing rules will change the order in which validation errors are reported within a file.

Fixes:

• Fixes issues when used in a Babel 6 environment (#228)
• Validation error of incorrect variable placement now includes a reference to the variable definition for easier debugging.
• Validation errors of ambiguous overlapping fields now includes clearer non-interleaved references to the overlapping fields.
• Input object validation errors now include more accurate error messages documenting which input object field contains the error (#204)

v0.4.12

New:

• Experimental customizable validation

v0.4.11

Fixes:

• Validator could false positive and be overly verbose when spreading an unknown fragment (8c62789)

v0.4.10

New:

• buildClientSchema() now supports deprecated fields #216
• Custom directives now supported by GraphQLSchema #215
• concatAST() utility added, which helps support validation of graphql fragments spread across multiple sources (3a6b4d1)

Fixes:

• Nested input objects with similarly named keys could falsely fail validation #206

v0.4.9

New

• Broadened legal use of interfaces to allow for additional arguments on implementing fields (see graphql/graphql-spec#110)
