-   **[Hermes Settings page](https://www.servicenow.com/docs/access?context=c-hermes-settings&family=australia&ft:locale=en-US)**

-   **[Encryption at rest for Hermes topics](https://www.servicenow.com/docs/access?context=encryption-at-rest&family=australia&ft:locale=en-US)**

Protect message data stored on broker disks by enabling encryption at rest on individual Hermes topics. Choose between ServiceNow-managed keys or customer-supplied keys using the Bring Your Own Key \(BYOK\) model.


 -   **[Expanded topic limits in Hermes](https://www.servicenow.com/docs/access?context=exploring-hermes-messaging-service&family=australia&ft:locale=en-US)**

Create more topics in Hermes with an increased topic limit. The total number of partitions across all topics can't exceed 960.

View Hermes data usage by source, including the total number of bytes received and bytes sent over time, in the Hermes Usage Dashboard.

-   **[Access restrictions by IP address](https://www.servicenow.com/docs/access?context=restricting-access-hermes-topics&family=australia&ft:locale=en-US)**

</td></tr><tr><td>

Brazil

</td><td>

-   **Configurable topic retention period**

Define custom retention policies for Hermes topics directly within Hermes Topic Manager to enable flexible data lifecycle management aligned with organizational compliance requirements and storage optimization strategies.

-   **Simplified topic options**

Streamline the administrative user interface with renamed and simplified topic options during topic setup and management.

See [Monitoring data usage](https://www.servicenow.com/docs/access?context=monitoring-data-usage-hermes&family=brazil&ft:locale=en-US).

-   **Enhanced Application ID filtering**

Improve usability with full descriptive names in the Application ID drop-down instead of abbreviated codes, and enable concurrent filtering across multiple Application IDs within a single usage query.

-   **Explicit external topic labeling**

Distinguish external topics from internal topics in the Hermes usage dashboard to eliminate confusion during usage analysis and reporting of cross-organization messaging patterns.

-   **Long-term usage data tracking**

Enable comprehensive trend analysis and capacity planning across longer time horizons with expanded usage data collection and retention infrastructure for enterprise messaging operations.

</table>## Changes

Between your current release family and Brazil, some changes were made to existing Hermes Messaging Service features.

Australia

</td><td>

</td></tr><tr><td>

Brazil

</td><td>

-   **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.
