ProxySQL has released version 3.0.6, introducing a multi-tier strategy with three tiers: Stable, Innovative (3.1.x), and AI/MCP (4.0.x). Version 3.0.6 enhances PostgreSQL support, improves authentication mechanisms, updates Prometheus metrics, and refines macOS support. The Innovative tier features an embedded time-series database and a traffic observer. The AI/MCP tier explores native integrations for proxy-level Retrieval-Augmented Generation (RAG) and autonomous database management.
