Datalore 2026.1: New Data Explorer Cells, Instance-Wide BYOK for AI, Stronger Security via Sidecar Containers in Kubernetes, and More | The Datalore Blog
Blog post from JetBrains
The latest release of Datalore, version 2026.1, introduces several key features aimed at enhancing data exploration and security for users. These updates, available to both Datalore Cloud and On-Premises users, include the introduction of data explorer cells, which allow users to explore and visualize data directly from dataframes without writing additional code. This feature enables quick dataset inspection, filtering, and chart generation, all within a single interactive cell. Additionally, the release supports the Bring Your Own Key (BYOK) for AI, allowing On-Premises administrators to choose between JetBrains AI or other AI providers, aligning with company security and data governance policies. For those deploying Datalore On-Premises on Kubernetes, the update includes the use of sidecar containers for enhanced security, where a privileged sidecar container manages external resource mounting, isolating it from the notebook agent container. These improvements aim to offer more flexibility, control, and security to users working with data.
