Fides 2.74.0 release notes

• 2.74.0: November 10, 2025

Helios

Detect and classify global data risks with comprehensive visualization for data mapping and reporting for modern Enterprise.

• Detection & Discovery UI Enhancements (Beta): Continued improvements to the Helios v2 UI with several new features and improvements to the Action Center:
  • Added keyboard shortcuts for reviewing fields, enabling faster review of large numbers of database results with quick classification actions accessible via Shift + /.
  • Improved schema tree view now limits the classification button to only display when classifiable resources are selected (Schema, DB, Table, Parent Field).
  • Tree expansion is now limited to 4 levels for better performance, with nested fields beyond 4 levels represented using dot notation in the list view.
  • Fixed an issue where selecting data category filters would clear the asset state filter.
  • Added database model for staged resource errors to better track and display issues during discovery.
  • Enhanced validation to prevent saving invalid data categories to fields.
• Performance Improvements: Significantly improved the performance of the aggregate results endpoint, which could previously degrade and slow down the Action Center when over ~250,000 fields or assets required action.

Lethe

Enterprise grade privacy request management and processing with a single orchestration layer for DSRs across vendors and systems

• New Request Manager (Beta): Continued enhancements to the new request manager UI with major improvements:
  • Improved filters now place filter values as query parameters in the URL, enabling easier saving and sharing of specific filter views.
  • Added support for custom request fields and custom identities in the UI for more comprehensive request management.
  • Cleaned up the design of list elements for a more streamlined experience.
  • Fixed handling of very long values in the request manager display.
• General Lethe Enhancements:
  • Added a memory dump output to the logs when the memory watchdog hits the 90% memory limit to aid in debugging memory issues.
  • Pending (new) requests can now be resubmitted for improved workflow flexibility.
  • PrivacyRequest cache now falls back to the database for identity and custom fields, improving reliability.
  • Added endpoint to bulk cancel requests for more efficient request management.
• Duplicate Request Management: Added duplicate DSR checking to the request runner to help identify and manage duplicate privacy requests.

Janus

High performance consent recording and orchestration for data sharing, built for enterprise data engineering and AI pipelines.

• Privacy Experience Fixes: Fixed issues storing and retrieving privacy preferences related to headless privacy experiences.
• Fides.js Improvements:
  • Fides.js now dispatches a synthetic FidesReady event when Fides.gtm() is called after Fides has already been initialized, improving integration reliability.
  • Fixed race condition causing gdprApplies to flip during TCF initialization.
• v3 Consent APIs: Development of the new v3 Consent API includes several foundational features:
  • Added consolidation on read for privacy preference v3 API.
  • Added new v3 current privacy preferences endpoint /api/v3/privacy-preferences/current.
  • Added identity definition API endpoints for more flexible identity management.

Integrations

• New Integration: Added new connector for BazaarVoice with access DSR support.
• Klaviyo Update: Updated Klaviyo integration to include List and Segment support.
• File Processing Improvement: Added replace mode for decoding context loggers to avoid decode errors with zip files, improving support for compressed file handling in integrations.
• UI Improvements: Fixed a visual issue with the integrations detail page on smaller screens.

Fides core

• Taxonomy: The taxonomy UI now supports configuration of custom taxonomies. This feature enables configuring additional dimensions of the Fides taxonomy that can be used to apply qualifiers such as sensitivity and risk level to other parts of the taxonomy. This will allow accurate labeling of certain data categories as sensitive under different privacy regulations and will be particularly useful for triaging database monitor results.
• Privacy Center: Improved Privacy Center FidesJS performance and reliability by caching bundles in memory and adding stale-while-revalidate and stale-if-error cache headers for improved CDN performance and origin failure resilience.
• Configuration: Dynamic Celery environment variables can now be loaded if they match the FIDES__CELERY__ prefix, providing more flexible configuration options for distributed task processing.
