Akka gRPC 1.0.0 Released

Dear hakkers,

We’re happy to announce version 1.0.0 of Akka gRPC!

gRPC is a transport mechanism for request/response and (non-persistent) streaming use cases. See Why gRPC? for more information about when to use gRPC as your transport.


You find the slides and code for this video on GitHub.


Supported by Lightbend

Starting at Akka gRPC 1.0.0, this module is now officially Supported as part of a Lightbend Subscription.

API stability

With version 1.0.0 we will start to provide a level of binary compatibility so you can have different versions of Akka gRPC as transitive dependencies.

Akka gRPC 1.0.0 still supports Akka 2.5.x and Akka HTTP 10.1.x, but we have made the necessary preparations so that the APIs work smoothly with Akka 2.6.x and Akka HTTP 10.2.x (yet to be released) as well.

Changes since 0.8.4
