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.
What's Updated

  • Performance & Pagination

    • Improved pagination reliability for streaming endpoints.
    • Refactored the Bun-based paginator to issue a single optimized query, improving performance

  • Kubernetes & Edge

    • Added Kubernetes RBAC resources for the edge-fluentbit service.
    • Improved Fluent Bit configuration.
    • Removed unused Kubernetes port definitions.
    • Autoscale-up is now disabled for generic clusters.
    • Fixed cluster creation flags to correctly align with feature flags.

  • Application & Deployment Reliability

    • Fixed node name validation in workload listing.
    • Improved schema validation by including existing resource parameter values.
    • Fixed deployment of previously stopped workloads in Docker clusters.
    • Improved workload injector performance and validation logic.
    • Improved handling of service accounts during workload updates.

  • Timeseries & ClickHouse Stability

    • Fixed an issue where the timeseries migrator could hang after completion.
    • Ensured table and column names are properly quoted to prevent forbidden character errors.
    • Corrected ClickHouse fill behavior to bypass interpolation when not provided.

  • API Specification

    • Added example to ts/create type in API specification for improved documentation clarity.
What's Deprecated
  • No features were deprecated in this release.
What's Deleted
  • Removed unused Kubernetes port definitions to simplify cluster configuration.
