It also displays detailed information about each sandbox, including status, data utilization, owner, last access, and allocation timestamps. * **Sandbox Templates and Data Reuse:** Enables delegated developers to reuse data via sandbox templates, streamlining testing by avoiding repetitive manual data entry. * **Data Generation Profiles:** Facilitates statistical sampling and curated data mapping from selected tables to populate sandboxes, supporting more efficient and relevant test data generation independently of sandbox copies. * **Sandbox Allocation and Retirement:** Provides functionality to allocate sandboxes to development teams and retire outdated sandboxes to optimize resource usage. * **Automatic Backup of Update Sets:** For instances with Developer Sandboxes installed after Zurich Patch 5, update sets are automatically backed up during instance upgrades, enhancing upgrade reliability. * **Support for Build Agent in Sandboxes:** Administrators and delegated developers can request, access, and manage isolated development environments on a shared underlying instance, providing developer isolation and parallelism for customer development environments. ## Changes and Deprecations * **Upgrade Enhancements:** Automatic backups during upgrades now function correctly, resolving previous issues related to upgrade reliability. * **Data Generation Plugin Deprecation:** All data generation metadata and non-metadata records are automatically deleted, and the data generation plugin is no longer discoverable. Sandbox initialization now operates independently of data generation logic, and references to data generation have been removed from sandbox templates. ## Upgrade and Activation Guidance * Before upgrading to Zurich, review and complete any required pre- and post-upgrade tasks to ensure a smooth transition. * Developer Sandboxes must be activated through your ServiceNow account manager and are available via the ServiceNow Store. ## Additional Information * No updates or changes were noted for browser requirements, accessibility, localization, or additional platform requirements between Xanadu and Zurich. * There were no removals of Developer Sandboxes features or functionality in this upgrade cycle.
