New Features

Live Reasoning Stream in Chat
Long-running AI responses previously showed only a static "Working…" spinner. Now the agent's reasoning streams into the chat in real time, so you can follow its thought process as it works.

Dash App Self-Correction via Screenshot Review
After a Dash app runs, the AI now reviews a screenshot of the result to catch visual issues like blank pages or broken layouts, and corrects itself if it finds a problem. This gives Dash apps the same quality check that charts already had.

Improvements

Faster Session Start
The agentic session and home page composer are now immediately interactive when you open the app. You no longer have to wait for a background service to finish loading before you can start typing.

Faster Deployment to Plotly Cloud and Dash Enterprise
Deploying a Dash app — packaging it, syncing credentials, and publishing — now runs end-to-end on a faster backend, making deploys quicker.

Faster, More Reliable Session Startup
A set of large, rarely-used Python packages (database connectors, geospatial libraries, document tools, and others) are no longer pre-installed by default, reducing the time it takes to start a new session. The agent can still install them on demand if your project needs them.

More Reliable Recovery After Restarts
When Studio restarts after a crash or update, interrupted sessions and in-progress tasks now recover more quickly and reliably, and active sessions are no longer incorrectly reset.

Fixes

Fixed App Deploy Failures
Deploying or generating apps could fail with a database error. This has been fixed.

Fixed Truncated AI Responses on Dash Enterprise
When using Plotly Studio through a Dash Enterprise AI proxy with certain models, agent sessions could fail immediately with an unsupported-feature error. Sessions now handle this correctly.

Fixed a Potential App Crash
Resolved a crash that could occur in the desktop app related to a recent dependency update.
