Commits: v2.0.0-rc.1...v2.0.0-rc.2

Breaking

• Merge graphql-compiler into relay-compiler (#2593)
• Selector type returned by environment.unstable_internal.getSelector(...) has changed.

Added

• ReactRelayContext is now exported from react-relay.
• Added fragment ownership model to relay-runtime: fragments can now point to the query that owns them, which removes reliance on React Context and gives us flexibility to experiment with new apis.
• Persisted queries: Enables a simple but straightforward mechanism to use persisted queries in open-source. (#2354)
• @arguments directive now supports literal values.

Experimental

• Added support for new @match directive for dynamically loading code and data dependencies determined by server. No user api is provided yet.
• Added support for @refetchable directive which automatically generates a query for a fragment that is “refetchable” (i.e. a fragment on Viewer, Query, or a type that implements Node). No user api is provided yet.

Fixed

• Fixed receiving payloads out of order in QueryRenderer.
• Fixed issue in Pagination Container when receiving new props.

Improved

• Improved compiler error messages, which now show locations in source.
• Updated the structure of generated ConcreteRequest to provide more flexibility for our fetching apis.
• Cleaned up Reader and Normalization AST representation.
