Standard lib or Akka for Scala.2.10.1?

Question

I am going to use Futures and Promises from scala.concurrent package in Scala 2.10.1. Should I use Akka instead ?

Answer 1

Akka futures and promises were moved into Scala standard library in 2.10 so there is no difference. It's not that you're using the standard scala classes - the old scala classes no longer exist and have been replaced by akka's.

Use akka actors as scala ones are deprecated in scala 2.11

See akka 2.0 to 2.1 migration for details of what is in the standard scala library now. http://doc.akka.io/docs/akka/2.1.2/project/migration-guide-2.0.x-2.1.x.html
