Plotly Newsletter, October 2026
Can you believe that October is almost over, and Halloween is tomorrow 🎃? Before you get ready for trick-or-treaters, catch up on what’s new with Plotly this month: three big product updates, fresh guides, and a live session on turning Figma designs into Dash apps.
What’s new
Dash Enterprise 6.3 is here. Any deployed app can now become an MCP server with one setting, so Claude and Claude Code can connect to it directly. It also runs on ARM64 and supports more Python versions, so more of your existing code runs as is. See what’s new →
Dash 4.5 is out! Callbacks can now stream results as they run, so LLM answers appear word by word instead of behind a spinner. New shared storage lets your app’s workers share cached results without setting up Redis, and pattern-matching callbacks are up to 4x faster. Learn more about Dash 4.5 → pip install -U dash
Plotly Cloud apps can now keep their files. Attach a persistent filesystem, and databases, uploads, and caches survive restarts and redeploys, and can be shared across your team’s apps. Available on Pro and Enterprise plans. Check out persistent filesystems → | See example apps →

From Figma to Dash: Transform Design Mockups into Production Apps
