2.5.x Migration guide

  • There is no longer a common module shared by the Scala and Java versions of Deadbolt, so there is no more usage of Java types in the API.
  • Types previously found in be.objectify.deadbolt.core.models are now found in be.objectify.deadbolt.scala.models.
  • be.objectify.deadbolt.core.PatternType is now be.objectify.deadbolt.scala.models.PatternType.
  • be.objectify.deadbolt.core.DeadboltAnalyzer has been re-implemented in Scala as be.objectify.deadbolt.scala.StaticConstraintAnalyzer.
  • Instead of an implicit Request, actions now receive an explicit AuthenticatedRequest that contains an Option[Subject].
  • The functions of DeadboltActions now return a Future[Result] in place of an Action[A].
