Breaking Changes

HTTPScaledObject CRD must be updated (#1419)

You must update the HTTPScaledObject CRD before upgrading the operator. The .status.conditions field now uses the standard Kubernetes metav1.Condition format.

If you have tooling that parses HTTPScaledObject conditions, update it to expect standard fields (lastTransitionTime, observedGeneration).

This fixes duplicate Ready conditions that caused issues with GitOps tools like ArgoCD and Flux.

Highlights

Wildcard host matching (#1411)

Use wildcard patterns like *.example.com to match any subdomain with a single HTTPScaledObject.

spec:
  hosts:
    - "*.example.com"  # matches foo.example.com, bar.foo.example.com, etc.

HTTP header-based routing (#1289)

Route requests to different backends based on HTTP headers. Multiple HTTPScaledObjects can now match the same host and path with different header requirements.

apiVersion: http.keda.sh/v1alpha1
kind: HTTPScaledObject
spec:
  hosts:
    - api.example.com
  headers:
    - name: X-API-Version
      value: v2
  scaleTargetRef:
    name: api-v2

Performance improvements (#1404)

The interceptor now uses significantly less memory under load, with reduced memory growth over time. Latency is also improved for high-throughput workloads.

Full-duplex HTTP/1.1 support (#1386)

Bidirectional streaming now works correctly - response bodies can start streaming while request bodies are still being sent.

Configurable request logging (#1375)

Request logging in the interceptor is now optional. Disable it to reduce log volume in high-traffic environments.
