## New Features

* **Zurich to Australia Releases:** Introduced capabilities include monitoring Hermes data usage by application and topic via the Hermes Usage Dashboard, synchronization of topic partition counts across Hermes clusters, and enhanced security with encryption at rest for Hermes topics using ServiceNow-managed or customer-supplied keys (BYOK).
* Australia added the Hermes Settings page for configuration management, expanded topic limits (up to 960 total partitions), IP address-based access restrictions, and a view-only role for administrators to access Hermes topics and namespaces.
* **Brazil Release:** Introduces configurable topic retention periods allowing custom data lifecycle management within the Hermes Topic Manager. It simplifies topic administration through streamlined UI options, improves Application ID filtering with full descriptive names and multi-ID filtering, explicitly labels external topics to clarify usage reporting, and enhances long-term usage data tracking for better capacity planning and trend analysis.

## Key Changes

* Coral theme became the default UI theme from Zurich, offering a refreshed and brand-neutral user experience with dark theme support for web and mobile.
* Brazil improved data query accuracy, now supporting extended date ranges beyond two months and correctly handling empty Application IDs in usage data filtering.
* Topic namespace parsing was fixed to correctly analyze Hermes topics without requiring explicit namespace definitions, enhancing metrics collection reliability.

## Removed and Deprecated Features

There are no removals or deprecations of Hermes Messaging Service features from Zurich through Brazil releases.

## Activation and Requirements

Hermes Messaging Service activation remains consistent across releases, requiring the ServiceNow Stream Connect Installer plugin (com.glide.hub.streamconnect.installer) or the Log Export Service application installation. No new additional requirements or browser specifications have been introduced.

## Accessibility and Localization

The Coral theme supports an accessible dark mode option for web and mobile to improve readability and reduce eye strain. There are no changes in localization or accessibility compliance across these releases.

## Practical Benefits for ServiceNow Customers

* Enhanced visibility and control over messaging data usage enable better operational insights and capacity planning.
* Improved security through encryption at rest and IP-based access restrictions safeguard message data integrity and access.
* Flexible topic retention policies and simplified management streamline administration and compliance with organizational data policies.
* UI improvements and refined filtering options facilitate efficient monitoring and troubleshooting of messaging workflows.

## Changes

Between your current release family and Brazil, some changes were made to existing Hermes Messaging Service features.  
{#dfrn3-hermesmessagingservice-summary__entry__18}

| Release | Release notes |
|-|-|
| Zurich | Coral theme :   Coral is now the default theme for new portal, web, and mobile experiences with Next Experience or Core UI enabled. This theme provides a fresh look and feel, featuring brand-neutral illustrations to enhance your user experience. A dark theme option is available for web and mobile experiences. |
| Australia | No updates for this release. |
| Brazil | Empty Application ID handling :   Topics created without an explicit Application ID are now correctly filtered and labeled in usage data queries. Previously, these topics would incorrectly appear in results when the "all values" filter selection was applied. Extended date range query processing :   Usage data queries now return accurate results for date ranges exceeding two months. Previously, queries spanning more than two months would display incorrect or corrupted data, limiting historical analysis capabilities. Topic namespace parsing :   Metrics collection now correctly parses Hermes topics without requiring explicit namespace definitions. This resolves parsing failures that previously occurred during topic analysis in the metrics collection pipeline. |
