Akka-HTTP
This release contains no known changes to API or functionality (hence the patch update) but comes with major changes in the libraries used. Previously, Spray was used to provide a REST API to slicebox internal API which is based on Akka actors. Spray has become part of the Akka project under the name Akka-HTTP and was recently made available in a first stable release. We have therefore upgraded from Spray to Akka-HTTP in this release which makes major future improvements such as streaming handling of DICOM data possible.
In this release we have also changed JSON libraries from spray-json to play-json since we have found play-json to be faster in demanding applications.
