Akka gRPC 2.1.0 Released

Dear hakkers,

We’re happy to announce version 2.1.0 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.


This version of Akka gRPC contains fixes to make Akka gRPC work on Scala 3 (thanks to @RomanLebid), proto3 optionals support thanks to @thesamet and various performance improvements thanks to @jrudolph, @patriknw, @viktorklang and @lomigmegard.

Changes since 2.0.0
