## Highlights

This release delivers a major end-to-end memory upgrade for UltraRAG, introducing persistent user memory, project memory retrieval, and a dedicated memory-aware RAG demo. It also makes the demo experience significantly more stateful and personalized with SQLite-backed authentication, persistent chat sessions, nickname and model settings management, and knowledge base visibility controls supporting public, private, and shared access.

The frontend is substantially refreshed through a React/Vite-based overhaul, the new Explore section, improved source-detail interactions, and a mobile optimization baseline. We also improve engineering robustness by fixing an async retriever initialization issue, adding compatibility guards for FastMCP 3.x-related builder changes and demo runtime cleanup, introducing CI smoke checks for the SayHello pipeline and frontend build, and adding a structured troubleshooting guide, alongside a broad round of backend and frontend dependency maintenance.
