The log rotation uses a schedule of seven shards, each covering five days. Existing log entries before the upgrade are truncated automatically. * **Performance Improvement:** In Zurich, it is recommended to upgrade replication sets to V2, which leverages the Hermes Messaging Service for enhanced performance and processing efficiency. ## New Features * **Zurich Release:** * Monitor scheduled replication sets via the IDR Monitoring Dashboard. * Track scheduled replication requests within the Scheduled Replication Requests related list. * **Australia Release:** * Enhanced IDR Diagnostics page with detailed test descriptions and results on a redesigned interface. ## Changes * **Zurich:** Introduction of the Coral theme as the default for new portals, web, and mobile experiences with Next Experience or Core UI enabled. The theme offers a fresh, brand-neutral look and includes a dark theme option to improve readability and reduce eye strain. * **Australia:** No changes reported. ## Deprecations and Removals * **Zurich:** Legacy replication sets were deprecated and are no longer supported. Additionally, the Key Management Service and VAULT Service Status tests were removed from the IDR Diagnostics page. * **Australia:** No new deprecations or removals. ## Activation and Subscription Instance Data Replication is a ServiceNow AI Platform feature that requires activation of the `IDR (com.glide.idr)` plugin, which needs a separate subscription. This applies to both Zurich and Australia releases. Customers should request a subscription to enable IDR functionality. ## Additional Information * No additional requirements, browser specifications, or localization changes were introduced in either release. * Accessibility improvements include the dark theme option introduced in Zurich's Coral theme, aiding readability and reducing eye strain. ## Practical Value for ServiceNow Customers * Monitoring capabilities enable you to track replication progress effectively, ensuring data consistency and operational transparency. * The redesigned diagnostics page in Australia facilitates easier troubleshooting with detailed test feedback. * Automated log rotation management improves system maintenance by managing error logs efficiently without manual intervention. * Upgrading replication sets to V2 enhances replication performance and reliability. * The Coral theme provides an improved user interface experience with accessibility benefits.
