### What's new {#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new}

Configurable topic retention period{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new-feature-1}
:   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{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new-feature-2}

:   Streamline the administrative user interface with renamed and simplified topic options during topic setup and management.See [Monitoring data usage in Hermes](https://www.servicenow.com/docs/access?context=monitoring-data-usage-hermes&version=brazil&pubname=brazil-servicenow-platform&ft:locale=en-US).

Enhanced Application ID filtering{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new-feature-3}
:   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{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new-feature-4}
:   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{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-new-feature-5}
:   Enable comprehensive trend analysis and capacity planning across longer time horizons with expanded usage data collection and retention infrastructure for enterprise messaging operations.

### What's changed {#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-changed}

Empty Application ID handling{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-changed-feature-1}
:   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{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-changed-feature-2}
:   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{#hermes-messaging-service-rn-2026-09__hermes-messaging-service-rn-2026-09-changed-feature-3}
:   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.
