v1.0.9

This release marks a milestone with the introduction of Online Training capabilities, empowering agents to learn and adapt continuously. It also significantly enhances the Skill & Tool System with broader compatibility (Spring Boot Fat JAR, Nacos, Git), and improves Streaming & Observability for enterprise-grade deployments.

🌟 Key Highlights

1. Online Training

Introduces foundational support for Online Training , enabling dynamic model fine-tuning at runtime and laying the groundwork for self-evolving agents (#703).

• Documentation: For implementation details, please refer to the Online Training Documentation.

2. Advanced Skill & Tool Integration

We have extensively upgraded the skill and tool ecosystem to support more dynamic and complex deployment scenarios.

• Flexible Skill Loading: Now supports loading skills directly from Spring Boot Fat JARs (#668), Git repositories (#690), and Zip files (#694), greatly simplifying plugin management and distribution.
• Nacos Integration: Added support for dynamically loading ReActAgent system prompts from Nacos, enabling real-time configuration updates without redeployment (#760).
• Tooling Enhancements: Introduced ToolSchemaModule to support parsing of the @ToolParam annotation (#783) and added support for relative paths in built-in file tools (#747).

3. Streaming & Observability

We have optimized the data flow and monitoring capabilities for clearer insights and better user experiences.

• Fanout Streaming: Added full streaming support for FanoutPipeline, enabling real-time feedback in parallel processing scenarios (#664, #700).
• Distributed Tracing: Fixed OpenTelemetry trace context propagation, ensuring complete visibility across subagent calls (#704).

🚀 New Features

• Planning:

  • Human-in-the-Loop (HITL): Added HITL support and changeHook management APIs to the PlanNotebook. Developers can now intervene, review, and modify agent plans during execution for greater control (#687).

• Model & RAG:

  • ID Generation: Auto-generate ChatResponse.id when the underlying LLM does not provide one, ensuring consistency (#721).
  • Dify RAG: Fixed the reranking_model JSON key in Dify RAG retrieval requests (#766).
  • DashScope: Updated to use requiresMultimodalApi for better multimodal support (#670).

• Infrastructure & Storage:

  • MySQL: Added support for hyphens (-) in MySQL database and table names (#706).
  • Elasticsearch: Bumped elasticsearch-java client to version 9.3.0 (#713).

🛠️ Refactoring & Fixes

• Core Stability:

  • Concurrency: Optimized AgentBase lock management to resolve concurrency conflicts (#733) and refactored ToolMethodInvoker to be stateless for better thread safety (#661).
  • Performance: Optimized the response handling of finishSubtask in planning (#673).

• Bug Fixes:

  • Hooks: Fixed the execution order ensuring SkillHook triggers later than StructuredOutputHook (#722).
  • Async Tools: Properly handled ToolSuspendException for synchronous throws within asynchronous tool branches (#791).
  • Generics: Fixed an issue where generic type information was lost in ToolMethodInvoker (#730).
