It offers a modern, brand-neutral look with a dark theme option to reduce eye strain. * **Australia and Brazil Releases:** No changes reported. ## Deprecations * **Zurich Release:** * Legacy replication sets deprecated and no longer supported. * Removal of the Key Management Service test and VAULT Service Status test from the IDR Diagnostics page. * **Australia and Brazil Releases:** No deprecations reported. ## Activation and Subscription IDR is a ServiceNow AI Platform feature requiring activation of the **IDR (com.glide.idr)** plugin, which needs a separate subscription. This applies consistently across Zurich and Australia releases. No changes for Brazil. ## Accessibility and User Experience * The Coral theme includes a dark mode option for web and mobile, which improves readability and reduces eye strain, supporting accessibility needs. ## Additional Information * No new browser requirements, localization changes, or additional requirements were introduced from Zurich through Brazil. * Highlight improvements include enhanced monitoring and tracking capabilities for scheduled replication sets and requests introduced in Zurich and Australia releases. ## Practical Guidance for ServiceNow Customers To optimize Instance Data Replication when upgrading to Brazil, ensure you: * Upgrade replication sets to V2 to improve replication performance. * Leverage the IDR Monitoring Dashboard and Scheduled Replication Requests list to track replication status effectively. * Use the redesigned IDR Diagnostics page to troubleshoot replication issues. * Enable and understand automated log rotation to manage error logs efficiently. * Activate the necessary plugin with an appropriate subscription prior to upgrade.
