• 🌐 Distributed Sessions - Session continuity across multiple server instances using URI-based resource sharing. This enables agents to maintain conversation history and state even when requests are handled by different server nodes, without requiring centralized storage infrastructure.

  • 🔍 RAG LlamaIndex Agent - New example agent demonstrating Retrieval-Augmented Generation (RAG) using LlamaIndex. Shows how to build knowledge-based agents that can query external documents and provide contextually relevant responses.

  • 📚 Citation Metadata - Enhanced MessagePart with CitationMetadata for improved source tracking and attribution. Enables agents to provide transparent references to their information sources, improving trustworthiness and enabling fact-checking workflows.

  • ⚡ High Availability Support - Deploy ACP servers with centralized storage backends (Redis/PostgreSQL) for scalable, fault-tolerant setups. Enables production deployments with multiple server instances, load balancing, and automatic failover capabilities.

  • 📝 Message Role Parameter - Added role parameter to Message structure for better agent identification. Supports user, agent, and agent/{name} formats, enabling clearer conversation tracking and multi-agent coordination.

  • 🔄 TypeScript SDK (Client) - Full TypeScript client library for interacting with ACP agents. Provides type-safe client implementations with comprehensive support for all ACP operations including sessions, runs, and streaming.
