v4.9.0

Added

• Add optional columnsEnum argument to the @whereConditions, @whereHasConditions
  and @orderBy directives #1150
• Exclude or include trashed models in @can when @forceDelete or @restore are used
  so the client does not have to filter explicitly #1157
• Add test trait \Nuwave\Lighthouse\Testing\MakesGraphQLRequestsLumen for usage
  with Lumen #1100
• Add test trait \Nuwave\Lighthouse\Testing\UsesTestSchema to enable using
  a dummy schema for testing custom Lighthouse extensions #1171
• Simplify mocking resolvers that just return static data #1177
• Add utility \Nuwave\Lighthouse\ClientDirectives\ClientDirective to correctly
  get the arguments passed through a client directive #1184
• Add streamGraphQL() helper method to \Nuwave\Lighthouse\Testing\MakesGraphQLRequests for
  simple testing of streamed responses, such as @defer #1184

Fixed

• Fix eager-loading relations where the parent type is an interface or union and
  may correspond to multiple different models #1035
• Fix renaming input fields that are nested within lists using @rename #1166
• Fix handling of nested mutation operations that receive null #1174
• Fix nested mutation upsert across two levels of BelongsTo relations #1169
• Apply query filters using an ArgBuilderDirective such as @eq when the argument
  is nested deeply within the input #1176
• Fix \Nuwave\Lighthouse\Testing\MakesGraphQLRequestsLumen test helper #1186
• Handle multiple instances of client directives with @defer correctly #1184

Deprecated

  is never called or used anywhere within Lighthouse. It will be removed from the interface.
