Changelog

New Features

Dash Enterprise administrators can now monitor the token spend for Plotly Studio. A new usage dashboard shows your own request history, and administrators can configure Studio to show usage across all users. Administrators can also set 1-day, 7-day, and 30-day token limits for users to keep token spending in check.

Classic Project Migration

Classic projects are now upgraded to the agentic project format automatically when Studio starts. Migration runs in the background, the project list shows the status of each project, and any project that fails to migrate is retried on the next launch. Your original classic project data is never deleted, and classic projects can’t be opened while their migration is in progress.

Fixes

Apps generated by Studio now do a better job of making their datasets available to Plotly Studio Embedded by default, when deployed to Plotly Cloud. Generated apps register each dataset as it loads, and if Studio Embedded is not installed or is turned off, the app runs normally.

New Features

Improved performance with XLSX files
The AI agent now converts large or complex data files, such as Excel workbooks, into Parquet format by default. Your apps load data faster, the converted files are included automatically when you preview or deploy, and file handling is more reliable across operating systems, including Windows.

Classic Mode Sunset

Classic projects and agent-created projects now appear together in a single list on the home page. The separate “Create a Classic Project” button has been removed. Your existing classic projects still appear in the list and open as before. You may also opt-in to migrating your classic projects to agentic projects until the next release.

Fixes

Fixed an issue where the project list would briefly flicker when you navigated back to it. The page now shows a loading placeholder until all your projects are ready.

Apps can now keep files across restarts, redeploys, and sleep.

A persistent filesystem is durable, team-level storage that you mount into an app at a path you choose, such as /data. Your app reads and writes it like a regular folder.

What's included

• Storage tab in app settings. Attach an existing filesystem or create a new one, set a mount path, and publish. The mount applies on the next publish or restart.

• Filesystems page. See every filesystem on your team, its status, and the apps it's attached to, along with your team's storage usage and cost.

• Share across apps. Mount the same filesystem into as many of your team's apps as you need.

• Regular filesystem behavior. Read, write, rename, append, and delete files and nested directories.

• Usage-based billing. There's no size to choose. Storage is billed on what's stored (in GB/mo). See pricing for details.

Availability: Pro and Enterprise plans.
