Attu 3.0 Beta: Multi-Cluster Management, AI Agent, and a Rebuilt Milvus Console

Attu 3.0 Beta introduces multi-cluster management, allowing users to connect to and manage multiple Milvus instances from a single interface with a persistent sidebar and health indicators. It adds persistent local state for connection configurations, agent history, and user preferences via a local database. A built-in AI Agent with over 50 Milvus tools enables natural language operations and diagnostics, including guided diagnostic skills for common troubleshooting scenarios. The data browser is redesigned with a hierarchical database -> collection -> partition structure, and operations like vector search, import/export, and schema management are integrated. The Ops and Monitoring area now includes a visual cluster overview, real-time Prometheus metrics, slow-query analysis, topology view, and GUI-based backup and restore with cloud storage support. It also supports Bring Your Own LLM (BYOL) for AI integration.
