v2.0.0-RC2

Please check the documentation for more details.

Features & Enhancements

• Qwen 3.7 model support — added support for Qwen 3.7 series models (e.g. qwen3.7-plus)
• Direct subagent messaging — send messages directly to a spawned subagent and receive its response without going through the parent agent's reasoning loop
• Subagent event stream forwarding — child agent intermediate events (text deltas, tool calls, etc.) are now forwarded in real time, each carrying a source path identifying the originating agent
• Event source tracking — all agent events now carry a source field to distinguish main vs. subagent events within the same stream, enabling consumer-side demuxing
• Custom model and prompt for Compaction / Memory — compaction and memory extraction now support dedicated lightweight models and custom prompts, independent of the agent's primary model
• Channel integration — new extension module family for IM platform integration (DingTalk, Feishu/Lark, WeCom, GitHub, GitLab), with a built-in ChatUI for an out-of-the-box conversational interface
• Unified distributed backend — new single-point configuration that consolidates all distributed storage components (state store, base store, sandbox snapshot) into one setup call. Built-in implementations for Redis, OSS, and MySQL
• Project-writable mode — when enabled, agent file writes are routed by path: workspace metadata goes to the workspace directory; everything else (code, configs) lands in the project directory. Designed for code-generation agents
• Runtime permission mode switching — dynamically adjust the permission mode per session at runtime
• Plan Mode improvements — improved plan file persistence and recovery, smoother tool-chain interaction, more robust approval flow
• Skill self-evolution enhancements — refined the propose → curate → promote closed loop, improved skill matching accuracy and cross-session reuse
• HTTP client timeout and retry policy adjustments
• Model resolution logic improvements
• Agent state records more running statuses

Breaking Changes

• Agent fully stateless — agents no longer hold mutable per-session state, a single agent instance can safely serve multiple concurrent sessions
• Unified state store — removed legacy session interfaces; unified on a new AgentStateStore abstraction with built-in in-memory, JSON file, Redis, and MySQL implementations, auto-partitioned by user and session
• Base store package renamed — base store interfaces for RemoteFilesystem moved to a new package; update your import paths accordingly
• Extension module coordinates refactored — several extension Maven coordinates have been reorganized by capability (e.g. agentscope-extensions-session-redis → agentscope-extensions-redis). Update <artifactId> in your POM
• Sandbox implementations extracted — concrete sandbox backends (Docker, Kubernetes, E2B, Daytona, AgentRun) moved from harness core into standalone extension modules. Add the corresponding extension explicitly if you need sandbox support

Bugfixes

• Fixed permission state losing context during cross-session restoration
• Fixed agentscope-all missing 4 sandbox extension modules
