Chat2DB Community 5.3.0

Chat2DB Community 5.3.0 is a major new baseline for the Community edition and a fresh start for regular releases and ongoing maintenance.

Highlights

• Unified versioning: Community moves from the separate 0.3.x line to 5.3.0, aligned with the current Chat2DB product family.
• Shared database client core: Community, Pro, and Enterprise now share the same database client foundation, with the public Community repository serving as the upstream for that shared core.
• Local-first experience: No registration or sign-in is required. Data sources, query history, tasks, dashboards, and AI configuration are stored locally on your device.
• Complete database workflow: Connect to data sources, browse metadata, edit and execute SQL, manage database objects and data, import and export data, save SQL and history, and build dashboards and charts.
• Extensible tooling: Use the Chat2DB CLI, MCP integration, and your own configured AI models.
