The end of the year is around the corner. Let’s look at what the Kubewarden project achieved in 2023!
Context-Aware graduation The context-aware feature graduated to stable during this year. We did this by performing a massive overhaul of the initial iteration. Context-aware policies can access information about Kubernetes resources defined inside the cluster. At evaluation time, these policies can make decisions based on this information. Such an example is the unique ingress host policy.

Kubewarden 1.9.0 has introduced even more features requested by the community, and we are excited to share them with you!
In this blog post, we will introduce the new Raw policy type.
Kubewarden as a generic policy engine Raw policies allow policy authors to write and execute policies that are not necessarily related to Kubernetes. This means that Kubewarden can be used as a general-purpose policy engine. For instance, you can use Kubewarden to validate any type of artifact: configurations, Terraform plans, test coverage, static analysis or even deploy Kubewarden alongside your web application to validate domain-specific requests.

Not even a month after the 1.8.0 release, today we are happy to announce Kubewarden 1.9.0! 🎉🥳
This release includes two major features that have been requested by our community.
Making Rego policies context-aware Context-aware policies have been introduced with Kubewarden 1.6.0. These policies can obtain information about other Kubernetes resources at evaluation time. This allows them to make decisions based not only on the information provided by the AdmissionReview object they receive.

Kubewarden policies can be written using either a traditional programming language (like Go, Rust, C#, Swift, …) or using a domain-specific language like Rego. It is required that the programming language can generate the necessary WebAssembly module for use by Kubewarden.
When using a traditional programming language, the communication between the host executing the policy and the WebAssembly guest (the actual policy) uses the waPC communication protocol. This protocol provides a bidirectional channel between the host and guest.

Today we are happy to announce the release of Kubewarden 1.8.0! 🎉🥳
This is a small release, focused on OpenTelemetry.
The OpenTelemetry Protocol (OTLP) got its first 1.0.0 version in July 2023; several libraries got their first 1.0.0 release, such as the Go metric SDK or the .NET Automatic Instrumentation.
Still, the OpenTelemetry stack is not yet stable, and unannounced backwards-incompatible changes still happen. You can have a look at the status of each of their libraries and protocols here.

Fresh in the already released Kubewarden v1.7.0 stack, we welcome a new module: the Audit Scanner!
Audit Scanner? Up until the release of Audit Scanner, Kubewarden was strictly a Dynamic Admission Controller, checking requests made against the Kubernetes API server with the deployed policies.
Yet policies evolve over time; new ones are deployed, and existing ones are updated. This can mean that resources that are inside the cluster are no longer compliant.

Recently, we have focused on improving the Kubewarden developer experience. We have been implementing features requested by the community.
Reference policies by their SHA Since kwctl release v1.7.0 we support referencing policies by their SHA.
Container engines such as Docker and Podman allow users to refer to images by their SHA sum.
As Kubewarden policies are distributed as OCI artifacts, we thought it would be a good idea to add the SHA support to kwctl, so that users have a familiar experience.

Today we are delighted to announce the release of Kubewarden 1.7.0! 🎊 🥳 Aside from the bug and stability fixes, this release is packed with new features. This post highlights the main changes, detailed blog entries will come in the next weeks covering each feature in depth.
Audit scanner A new component has been added to the Kubewarden stack. Its name is audit-scanner and it allows administrators to assess the compliance level of the clusters secured by Kubewarden.

We are excited to announce a variety of updates, fixes, and enhancements for Kubewarden components!
This release primarily focuses on improvements to Kubewarden telemetry and dependency updates.
Telemetry Enhancements and Fixes The Kubewarden controller has received several fixes and improvements in the telemetry department. These include a streamlined process for users to deploy a policy server with telemetry enabled, as well as a bug fix related to the controller’s available metrics.
