Metabase version 0.30 introduces significant changes aimed at improving user experience by enabling better organization and accessibility of dashboards, questions, pulses, and collections. The update allows dashboards and pulses to be organized within collections, similar to saved questions, with the ability to create sub-collections, enhancing hierarchical organization. A new app-wide search bar has been added for quickly locating items, and the homepage has been redesigned to feature sections like "Start Here," "Our Analytics," and "Our Data," offering a more streamlined navigation experience. During the upgrade, existing dashboards, pulses, and questions not previously organized in collections will be automatically migrated into new collections with admin-only access permissions, ensuring security until permissions are adjusted. Users are advised to back up their Metabase application database before upgrading and are encouraged to provide feedback on the pre-release version.
