Whats New In Our Products ?

Kelvin UI

What's New

  • API Access configuration screen: New configuration screen on deployment for apps and connectors, allowing per-deployment * API service account permissions.

  • Asset Page Data Explorer widget: New time range configurations allowing users to select which options are available and set the default time range.
  • Asset relationships:
    • In the Data Explorer, when multi-asset view is enabled, users can quickly select related assets.
    • On the Asset Page, users can visualize asset relationships directly from the page header.
    • In the Asset Table, users can navigate to related assets.

What Changed

  • Improved authentication redirects for faster page loading times.

Bug Fixes

  • CSV publisher now properly recognizes existing asset/datastream pairs as already in use.
  • Data quality configuration errors no longer persist after re-uploading a valid file.
  • Datastream names are now visible when creating data tags.
  • Dropdown lists now display the correct hover styling state.

Kelvin API

What's New

  • Application & Workload Management

    • Dedicated Service Account per Workload Deployment: 
    • Each workload deployment now receives its own dedicated Service Account, improving security isolation and access control.

  • Workload Service Account Management Improvements:

    • Service Accounts are now automatically created when updating workloads that previously did not have one.

  • App Version Inheritance Enhancements:

    • When creating a new app version, default sections can now partially inherit configuration from the previous version — simplifying version management and reducing duplication.

  • Optional Docker Image Validation. You can now:

    • Skip Docker image existence validation when creating an app.
    • Disable Docker image delete checks when validation is disabled. This improves flexibility for private registries and CI/CD workflows.

  • Docker Auth API:

    • Introduced a new Docker Authentication API service for managing registry credentials.

  • API Permissions in App Defaults:

    • Applications can now define API permissions directly within default configurations.

  • Improved Schedule Creation Validation:

    • Schedule creation now validates using all parameters against schema definitions for stronger consistency and reliability.
