Release Notes for Styra DAS

This page describes the release notes for Styra DAS delivered in November 2021.

Release Summary

Styra is built on the Open Policy Agent (OPA), a popular and widely deployed open source project developed by the founders of Styra. With primary credibility for the underlying technology, the Styra team and technology are both proven in production across verticals. Styra enables enterprises to define, enforce, validate, and continually monitor security, compliance and operational policies across the cloud-native application stack. Styra has reinvented the authorization solutions to mitigate customer risk, and reinforce commitment to trust and transparency in safeguarding customers’ data. Styra’s Declarative Authorization Service (DAS) is a sophisticated management plane that provides context-based guardrails, built from a graphical policy library to mitigate risk, reduce human error and accelerate development. Styra makes it possible for enterprises to implement policy-as-code controls and to prove their effectiveness to both internal and external security and compliance audiences.

This Styra DAS 20211130 release delivers the following new enhancements.

New Features and Enhancements

This section describes the new enhancements in Styra DAS 20211130.


  • Starting with this release, /v1/systems and /v1/systems/instructions APIs add token access events to the activity log in addition to returning the bearer tokens.


  • The Styra DAS documentation is updated with a new look and feel.


  • This release allows you to check the status of your data source for successful state or errors it may have encountered.

  • The User Activity tab is moved from the Access Control tab to its own main section. The User Activity tab displays live or historical logs of user activity. The user activity log can be filtered by Outcome type and a case-sensitive free form text field for specific queries. The user activity log now can also be exported to S3 buckets; the export configuration settings is available in the Settings >> User Activity Export pane.


  • This release sets the default system AuthZ OPA policy for the Kubernetes V2 system type more restrictive by removing access to the root API and static HTML OPA landing page.

New Features and Enhancements

This section describes the new enhancement in Styra DAS 20211123.


  • Starting with this release, you can now disable logins with a username and password entirely and use only SSO for authentication.

Issues Fixed

This section describes the issue fixed in Styra DAS 20211123.

This Styra DAS 20211116 release delivers the following new enhancements.

New Features and Enhancements

This section describes the new enhancements in Styra DAS 20211116.


  • Starting with this release, POST /v1/datasources/$id API supports preview=true query parameter. It also accepts the whole data source configuration to validate the configuration and preview the data in JSON format.

  • styra local plane (SLP) statuses are now available through the GET /v1/agents/slps API endpoint.

  • The minimum OPA agent version (minimum_opa_version) running for a system or all systems matching a stack is now reported in the GET /v1/systems/{id} and GET /v1/stacks/{id} APIs correspondingly.

  • GET /v1/stacks/{id} now also returns the list of system IDs matching the stack (matching_systems) and GET /v1/systems/{id} returns the list of stack IDs matching the system (matching_stacks).

  • The list of errors reported for the system is extended with the latest bundle status. If there are any compilation errors or if it requires more recent OPA version instead of the oldest version the system agent has, then the errors are reported in the systems API and displayed in the DAS UI with system errors and warnings.


  • Starting with this release, bundles which use Rego features that are not available for the system will not be activated automatically, but requires manual activation with force flag.

  • The minimum required OPA version is now reported for each new bundle in the Bundle Registry. It is available through the /v1/systems/{id}/bundles API (minimum_opa_version field).

  • This release updates the Envoy and Istio systems' OPA instances configured in Quick Starts to only listen on localhost. However, diagnostic endpoints like health are still open generally on port 8282.

Data Sources

  • Kubernetes data source configuration now supports a new format in the masks section. A numeric [0] or wildcard [_] index is used to remove the resources in array properties.

    • spec.template.spec.containers[0].env # exclude first item from containers array
    • spec.template.spec.containers.env # exclude environment sub-objects of containers object
    • spec.template.spec.containers[_].env # exclude environment objects from all items in containers array
    • * # whole resource


  • The Data Sources section in the OpenAPI documentation is updated with the list of supported categories and examples for each category.

  • The Operations page is updated with the data source’s common properties.


  • When adding an HTTPS data source, you can now provide both public and private headers which are useful for authentication.

  • Decision export validation now allows usage of _ and . for Google Cloud Storage bucket names.

  • This release allows DAS to display bundle compilation errors when a policy bundle cannot be compiled.


  • The default OPA system Authorization policy is added to all Mesh system types and enables the basic Authorization on their OPA instances. The added policy does not apply by default to the Kong Mesh and Kuma system types as they do not enable OPA Authorization. For more information on OPA Authorization, see the Security page.
