Major New Features

RAG Module

• Introduced a native RAG (Retrieval-Augmented Generation) module with full support for distributed, multi-tenant, and multi-session RAG services, significantly enhancing knowledge retrieval capabilities.

Long-Term Memory Middleware

• Added a mem0-backed long-term memory middleware, enabling agents to retain persistent memory across sessions.

Budget Control Middleware

• Introduced BudgetControlMiddleware for enforcing token budget limits, helping teams manage and control API costs effectively.

Tool-Level Onion Middleware

• ToolBase now supports onion-style middleware at the tool level, allowing flexible pre/post-processing logic to be injected around tool execution.
