Release Notes

• Breaking Changes: The configuration database and CSV data from previous versions are not compatible with JEDI v4. The breaking changes were made to prepare JEDI for AI/ML features.

  The new CSV data storage format is now compatible with AI/ML libraries and easier to import into other data workflows. The included data migration tool allows you to import data from earlier versions.

• NEW: Grid Dashboard - A new dashboard builder with drag-and-drop grid layout and a wide selection of chart types including:

  • Donut
  • Events
  • Circular Gauge
  • Dual-Range Gauge
  • Compass
  • Pie
  • X-Y
  • And more
• NEW: Table Dashboard for displaying reports.
• NEW: CSV data storage engine for better compatibility with AI/ML/data science workflows.
• NEW: Data migration tool for importing data from previous JEDI versions.
• NEW: Arduino UNO-Q data collector support with default configuration.
• NEW (Experimental): Built-in MCP server and standalone MCP gateway enables AI agents such as Claude Desktop, Claude Code, OpenAI Codex, and Google Gemini to interact with JEDI for creating dashboards and analyzing data. Stay tuned for more features.
• NEW: Start with ready-to-use profiles (templates).
• NEW: Data Inspector - Provides a view of inbound data captured by JEDI in real-time for diagnosing issues.
• NEW: ARM64 Linux support.
