User Controlled App Updates
To prevent workflow interruptions, we have modified how application updates are handled. Instead of mandatory updates during startup, a new notification modal allows you to choose between installing the update immediately or scheduling it for the next time you launch the application.
Enhanced Publish Status
The data app publishing process now provides more transparency and control. The Publish button has been updated to include a dropdown menu for clearer navigation. Additionally, the button now displays real-time status updates, including Uploading, Building, and Published, so you can track the progress of your deployment without guesswork.
Fixes
Preview System Stability
Resolved an issue where data view previews would occasionally fail to load after a user had viewed an app preview.
Implemented a cache clearing mechanism to ensure that data previews render correctly and reflect the most recent changes.
Dependency Maintenance
Updated several core backend packages and script libraries, including Numpy and Pandas, to improve general system performance and security.

Improvements
Faster Application Launch: Optimized the startup process to ensure the application opens quickly, even for users with a high volume of saved projects.
Better Error Links: Replaced broken "Learn More" links in error messages with functional "Report Issue" links that direct to our feedback portal.
Data Loading Performance: Improved data caching mechanisms to ensure consistent data loading performance.
Reduced File Handle Usage: Improved database connection management to prevent "too many open files" errors on macOS.
Project List Refresh: Resolved an issue where the project list would timeout or fail to refresh after the application had been idle for an extended period.

Plotly Studio
Improvements
Enhanced app preview system: The preview system has been updated to provide a more responsive user experience and a more reliable workflow when restarting previews.
Project deletion indicator: A spinning indicator has been added to the project deletion process. This ensures users have clear visual confirmation that the removal operation is in progress.
Bug Fixes
Python dependency security updates: The Python requests library has been updated to version 2.33.0 to address a security vulnerability (CVE-2026-25645).
Explore mode performance: Resolved performance degradation when rendering complex visualizations in Explore mode.
Windows reliability: Windows Corrected an issue where certain Windows security configurations prevented the backend service from launching.

Improvements
Reliable AI Generation
Plotly Studio now has automatic retry logic with intelligent back-off timing. This ensures that app generation remains consistent and successful even during periods of high service demand or temporary interruptions.
Build Stability
General improvements have been made to ensure a more stable environment and eliminate unnecessary system warnings.
March 25th, 2026
Improvements
Enhanced Windows Startup Reliability
We have implemented automatic detection and repair protocols for startup failures on Windows. The system now identifies and fixes corrupted environment dependencies and handles Application Control issues automatically, ensuring a more consistent launch experience.
Actionable Error Reporting
Error messages for critical startup failures have been rewritten to provide clear, actionable information, making it easier to resolve local environment issues.
Dependency Recovery
Fixed a bug where corrupted Python dependencies would cause a permanent failure at launch. The application now attempts to recover the environment automatically to prevent persistent crashes.
March 25th, 2026
New Features
Custom Context In Initial Charts
The application now prioritizes custom user context when generating the initial set of six charts for new projects. This ensures that the first visualizations you see are more relevant to your specific data and presentation needs from the moment you start a new app.
Improvements
Improved Cloud Publishing
The timeout for publishing applications to Plotly Cloud has been increased from 60 seconds to 5 minutes. This change ensures that users with slower internet connections can successfully deploy larger apps without encountering timeout errors.
General Performance And Stability
The application now manages database connections more efficiently, particularly on macOS, to prevent system errors. Additionally, backend startup processes have been optimized to reduce wait times and prevent the application from hanging during the initial launch.
Fixes
Login And Authentication
Fixed a race condition that caused the application to become unresponsive after completing browser-based authentication.
App Management
Fixed a bug that resulted in apps being published to Plotly Cloud with blank names.
Resolved an issue where fresh installations could fail to start due to incomplete backend environment setup.
Project Navigation
Fixed inconsistencies in the project card menus to ensure that edit and delete options function correctly.

Plotly Studio
Fixes
Application Preview Reliability
The application preview process has been updated to handle concurrent starts more gracefully. The system will no longer report errors if a preview is already running, resulting in a more reliable restart experience when developing applications.
PDF Loading States
The visual indicators for loading PDF documents have been standardized. Users will now see consistent progress indicators and more descriptive error messages if a PDF fails to load.
Project Navigation
Resolved an issue where selecting a draft project from the project list would incorrectly direct the user to the App tab. Clicking a draft project now correctly navigates to the Data tab.
Team Creation On-boarding
Fixed a bug affecting the creation of new teams in the cloud environment. This ensures that new teams are immediately available and selectable in the team picker.

Plotly Studio
Improvements
Interrupted Generation Recovery
The system now detects when a component generation is interrupted, such as when the application is closed unexpectedly. These components will display an Aborted status along with a prompt to regenerate from the original instructions so you can complete your work.
Enhanced Generation Feedback
The project interface now provides clear notifications if a background generation task encounters an error. This replaces previous instances where a process might fail without providing specific feedback.
Faster Application Previews
Optimization of the startup sequence and loading interface has reduced the time it takes to preview an application by approximately 50%.
Credential Management On Windows
The process for saving large credentials, such as those required for BigQuery, has been updated to bypass Windows Credential Manager size limits. Additionally, if a credential fails to save, the system will now provide a specific error message.

Plotly Studio
New Features
Project Team Management
Users can now move projects between teams using the new Copy to Team option. This feature includes the ability to rename the project during the transfer and provides progress status indicators.
Improvements
App Startup Performance & Fixes: Implemented automated repair processes for Python environments to prevent startup failures and reduced unnecessary log output. The application now launches more quickly due to background processing of analytics initialization.
