Dear hakkers,

We are happy to announce the 10.1.6 release of Akka HTTP. 10.1.6 is the seventh release in the 10.1.x series of Akka HTTP. See the full list of changes below. A main improvement is that 10.1.6 was built using Scala 2.12.8 which allows to use Akka HTTP from Java with JDK 11.

Migration Notes

• akka-http now requires to be run with Akka 2.5.19+ to support JDK 11 from Java (we maintain binary compatibility during the Akka 2.5.x series so the update should be painless).
• RoutingSettings were moved to akka-http from akka-http-core (where they logically belong). Make sure to depend on akka-http when referencing this class (which your code will very likely already do because RoutingSettings cannot be used without the akka-http module).
• akka-stream-testkit is now a provided dependency for akka-http-testkit, if you use akka-http-testkit also add a dependency to akka-stream-testkit into the mix

Changes since 10.1.5

For a full overview you can also see the 10.1.6 milestone:
