App Studio Changelog

App Studio Editor

This section documents changes to the App Studio editor. This is the UI where you preview and customize your App Studio app. If you are using App Studio on Dash Enterprise, you’ll have access to additional functionality provided by the App Studio workspace, for example functionality that is directly within notebooks and the IDE. See the “App Studio Workspace” section below for details of the changes from the workspace release that are relevant to App Studio workspaces.

What version of the App Studio editor am I using?

When viewing an app preview, you’ll find the App Studio editor version in the bottom-right corner:
