In 2025, we are evolving that story to bring more added value for Spring developers, either in Java or Kotlin.

There's a new release of the amazing—if experimental—Spring gRPC project: version 0.4.0. I won't get into the nitty-gritty of all that's new, but I just wanted to highlight how elated I am to use it and walk you through the step-by-step path to gRPC joy.
