Microsoft DevBlogs·medium signal

Microsoft shipped Agent Framework 1.0 (open-source, .NET + Python) on April 3, unifying Semantic Kernel's enterprise foundations with AutoGen's orchestration. Stable features: multi-provider support (Azure OpenAI, Anthropic, Bedrock, Gemini, Ollama), middleware hooks, memory architecture with vector retrieval, graph-based workflow engine with checkpointing, and five multi-agent patterns (sequential, concurrent, handoff, group chat, Magentic-One). May preview additions include DevUI browser debugger, Foundry hosting, GitHub Copilot SDK, and Claude Code SDK integration. YAML declarations enable version-controlled agent definitions.
