v0.3.0

• #45 - Added Long scalar type

• #49 - UpdateCtxAction should also work for query types

• #50 - Sanity check - fields should have unique name within the same type definition

• #31, #32 - More test coverage for "projections" and "deferred" features

• #51 - Custom exception handler now should return message and list of additional filed

• The interfaces property syntax changed. In order to ensure type safety, improve type inference and allow type-class based relations between InterfaceType and ObjectType you now need to use following syntax:

  val PersonType = ObjectType("Person", interfaces = interfaces[Unit, Person](NamedType, BeingType), fields = ...)

  instead of old syntax

  val PersonType = ObjectType[Unit, Person]("Person", interfaces = NamedType :: BeingType :: Nil, fields = ...)
  
  // or
  
  val PersonType = ObjectType[Unit, Person]("Person", interfaces = List(NamedType, BeingType), fields = ...)

• Fields in ObjectType and InterfaceType got small convenience method fields. You now can use it like this:

  val DogType = ObjectType("Dog", fields[Unit, Dog](
    Field("name", OptionType(StringType), resolve = _.value.name),
    Field("barks", OptionType(BooleanType), resolve = _.value.barks)))

• withPossibleTypes was introduced on InterfaceType and Field in order to provide a convenient way to the list of possible implementation types of interface

• Added convenience method Executor.execute

• Other minor improvements to make sangria-relay possible
