New in this release:

• Most of JsonVisitor is now automatically generated.
• The experimental GraphQL schema definition syntax from graphql/graphql-spec#90 is now supported. Because the syntax is experimental, it is not on by default. To use the support, call graphql::parseStringWithExperimentalSchemaSupport or graphQL::parseFileWithExperimentalSchemaSupport.
• Location information in the AST is now more correct.
• ast::Node::accept() is now const.

User-facing changes:

• Support the null value.
• Fix Unicode unescaping bug.

libgraphqlparser-developer-facing changes:

• Upgrade to gtest 1.8.0.
• Upgrade to flex 2.6.2.

API-breaking change to match graphql-js: ArrayValue is now known as ListValue.
subscription is now accepted as an operation type instead of being rejected as a syntax error.
Some installer fixes.

dump_json_ast bugfix: Don't produce invalid JSON for inline fragments without type conditions.

Fixes for some memory leaks.
Track 2 upstream GraphQL language changes from October: make operation name optional and make type conditions on inline fragments optional. Sorry for the delay.

Lexer improvements:

• Track Unicode changes in upstream GraphQL spec
• Escape non-printable characters in error messages

Build system improvements:

• support for out-of-source builds
• Require only cmake 2.8
• make install support

Functionality:

• ast.py improvements from @eapache
• graphql_ast_to_json exposed in the C API

Initial release.
