Release Notes for Self-Hosted Styra DAS

Self-Hosted Styra DAS 0.16.4 was released on December 18th, 2024.

New Features and Changes​

Beta UI Additions​

Added Format button to policy editor. Moved Discard Draft in policy editor beside the Draft button. Added support for on-premise datasource agent configuration for HTTPS datasources.

Rego format API supports v1 syntax re-formatting​

The /v1/rego/fmt API adds the boolean v1 query parameter, which will reformat a rego v0 syntax policy to add the rego.v1 import and use rego v1 syntax.

Activity API performance improvements with buffered activity writer​

Improved the performance of the /v1/activity API when using the buffered activity writer configuration.

Fixed Issues​

System Prometheus metrics resulted in unexpected warnings in the UI​

For some system configurations, the active_opas, opa_missing_active_system_bundle, or opa_not_using_active_system_bundle Prometheus metrics could result in errors or warnings shown in system Deployments tabs. These metrics have been moved to only be reported as Prometheus metrics moving forward.
