May 2025: Delivered Contextual Button Actions in Conversations for wire-apps-jvm-sdk, enriching ButtonAction with sender and conversationId by unpacking from the generic message and constructing WireMessage.ButtonAction for richer context in conversations. This enables more precise action handling in chat threads, improves UX consistency, and provides richer data for analytics and debugging. Implemented in wire-apps-jvm-sdk, ready for integration into client apps and downstream services.
