Release Notes for Self-Hosted Styra DAS

Self-Hosted Styra DAS 0.16.8 was released on April 30th, 2025.

Self-Hosted Environment Changes​

Agentloader v2 debug logging option​

A debug logging option has been added for Agentloader v2 to help self-hosted customers better identify decision indexing bottlenecks for high decision volumes, which can be enabled with the AGENTLOADER_DEBUG_ENABLED feature flag.

More granular control of compliance jobs​

For customers with uneven load of System vs Stack compliance jobs, new feature flags are available for more granular control over System and Stack compliance job limits and configuration patches. This is particularly useful for customers with Kubernetes Stacks with many matching Systems, especially with large System cluster resource datasources. Contact your account representative to determine if this granular control for compliance jobs is a good match for your use case.

Decision timeseries latency Prometheus metric​

The decisions_timeseries_latency_seconds Prometheus metric has been added, which measures the time between a decision and processing for decision timeseries metrics in DAS. This metric can be monitored to determine if the timeseries service needs to be scaled up to handle increased decision volume.

  • The new UI now supports the same configuration for decision export at the system level as the legacy UI when using Agentloader v2.

  • Users with a System Manager role can create policies in the Policy Builder.
