March 2026
2 releases: 1.1.2.1 → 1.1.2.2
March brought significant enhancements to agent orchestration and workflow capabilities in Spring AI Alibaba. The release introduced multiple patterns for coordinating multiple agents and managing complex task delegation.
Highlights
- AgentScope integration wraps ReActAgent for use in graph workflows.
- Subagent pattern enables task delegation to specialized agents via Task/TaskOutput tools.
- Supervisor pattern centralizes control over multiple tool-based agents like calendar and email.
- Skills system allows agents to load skill content on demand with progressive disclosure.
- Routing patterns (simple and graph-based) enable intelligent query classification and parallel agent invocation.
New
- AgentScopeAgent wraps AgentScope ReActAgent as a BaseAgent for graph workflows.
- Subagent orchestration with task delegation to specialized sub-agents (codebase explorer, web researcher, etc.).
- Support for both Markdown and API-defined sub-agents in subagent pattern.
- Supervisor agent pattern that wraps calendar and email agents as tools and invokes them on demand.
- Skills loading system with on-demand skill content retrieval and progressive disclosure of skill descriptions.
- Simple LlmRoutingAgent for query classification and parallel specialist agent invocation (GitHub, Notion, Slack).
- Graph-based routing with LlmRoutingAgent as StateGraph node including preprocess, postprocess, and merge nodes.
- Handoff patterns supporting single-agent step progression and multi-agent conditional routing between agents.
Improved
- ModelInterceptor now injects step-specific system prompt and tools per turn for single-agent handoffs.
- System prompt optimization shows only skill descriptions instead of full skill content for smaller context windows.
Fixed
- Several bugs in version 1.1.2.1 were resolved in version 1.1.2.2.
