IAM roles for S3 and Redshift, notebook locking & custom chart tooltips

Role-based authentication for S3 and Redshift

We've introduced a new, secure way to connect to your S3 buckets and Redshift data warehouse - now available through IAM role authentication! This feature leverages AWS's native role-based access control, providing a robust security enhancement over traditional static keys. By using IAM roles, you can benefit from:

• Automatic credential rotation: temporary credentials that reduce the risk of long-term exposure.
• Simplified permissions management: enables more precise control over S3 resources, adhering to the principle of least privilege.
• Eliminated need for static credentials: decreases the potential for security breaches.

To set up your connection, choose the “IAM role” option in the "Authentication" section, input the Amazon Resource Name (ARN) of the role you wish to use, and update the trust policy as outlined. This process applies similarly for both S3 buckets and Redshift clusters.

For step-by-step instructions and more details, visit our S3 and Redshift docs.

Notebook locking

We’ve all been there - you go to run an app or a notebook, and it doesn’t work because someone accidentally changed something they shouldn’t have. To prevent these frustrating mishaps and ensure your work remains stable, we’re introducing notebook locking.

Simply enable the lock from the notebook’s context menu. While locked, the notebook can still be run, shared, or commented on—just no edits allowed. When updates are necessary, users can unlock it, make their changes, and rest assured that it will automatically lock again afterward.

Custom tooltips on charts

Ever needed to show just a bit more information on a chart without cluttering the entire visualization? Our new custom tooltips feature is here to help. Now you can enrich your charts by selecting additional data points to display from any column in your plotted dataframe—not just those configured on the chart.

It’s perfect for highlighting more information for an unusual data point on a scatterplot or adding context with an extra metric on your bar charts, all without overwhelming your audience.

Simply go to the Display tab and choose the columns you wish to display in the Data selector in the Tooltips section.

Scheduled projects view

Stay on top of your automated workflows with our new scheduled project view! This handy new section, located in the workspace navigation sidebar, provides a clear overview of all projects in your workspace that have automation set up, showing exactly when each project is scheduled to run.
