-Last week, we https://quarkus.io/blog/a2a-project-launches-java-sdk/[announced] that our https://github.com/a2aproject/a2a-java[A2A Java SDK] has been contributed to the official A2A project! This was a collaboration between our WildFly and Quarkus teams at Red Hat and Google. Today, we have released A2A Java SDK 0.2.3, which aligns with the v0.2.3 version of the https://github.com/a2aproject/A2A/tree/v0.2.3[A2A specification]. In this blog post, we'll cover how to easily get started with Quarkus and A2A using the A2A Java SDK.
