Release KEDA v2.20.2 🚀

⚠️⚠️⚠️⚠️ ⚠️ Please read upgrade notes if you are upgrading from version < 2.20.0: https://github.com/kedacore/keda/releases/tag/v2.20.0 ⚠️⚠️⚠️⚠️⚠️

Improvements

General: Introduce a dedicated HPAActive condition on ScaledObject mirroring the HPA's own ScalingActive status, so transient HPA metric gaps no longer flip the Ready condition to False (#7914)

Fixes

General: Fix concurrent map writes panic in the shared root CA CertPool (#7910)

General: Fix nil pointer dereference in AWS Secret Manager TriggerAuthentication when awsSecretManager.credentials is omitted and no awsSecretManager.podIdentity is set (#7927)

General: Fix nil pointer dereference in customScalingStrategy.GetEffectiveMaxScale when customScalingQueueLengthDeduction is omitted; the optional field is now treated as zero deduction instead of panicking (#7798)

General: Fix nil pointer dereference in GetCurrentReplicas when a Deployment/StatefulSet/ReplicaSet is returned from the informer cache with an undefaulted spec.replicas; a nil value is now treated as the Kubernetes default of 1 instead of panicking (#7863)

General: Fix ScaledJob CRD validation to include "default" as a valid value for scalingStrategy.strategy (#7855)

General: Guard GetCurrentReplicas against nil Status.ScaleTargetGVKR to prevent operator panics under the cache race documented in (#4389) / (#4955)

General: Restore core "" API group in events RBAC so that client-go's event broadcaster can write legacy events (#7922)

General: Restore gRPC reconnect backoff in the metrics service client; an unset Backoff in WithConnectParams disabled backoff and caused a zero-delay reconnect loop that flooded logs when keda-operator was unreachable (#7856)

General: Share HTTP transports across scalers to reuse connection pools and avoid re-dial storms at high ScaledObject counts (#7789)

General: Treat negative external metric values as zero to prevent incorrect HPA scaling (#7880)

Azure Blob Storage Scaler: Fix globPattern never matching when written in path-style with a leading /, since blob names never have one (#6492)

MongoDB Scaler: Disconnect the client when the initial Ping fails so the background topology-monitoring connections opened by mongo.Connect are not leaked (#5612)

Full Changelog: v2.20.1...v2.20.2

Release KEDA v2.20.1 🚀

⚠️⚠️⚠️⚠️ ⚠️ Please read upgrade notes if you are upgrading from version < 2.20.0: https://github.com/kedacore/keda/releases/tag/v2.20.0 ⚠️⚠️⚠️⚠️⚠️

Fixes

General: Fix concurrent map read/write data race in fallback updateStatus that caused panics when multiple triggers were scaling simultaneously (#7838)

General: Fix KEDAScalersStarted "Started scalers watch" event not being emitted for ScaledJobs because it shared an events.k8s.io aggregation key with the per-scaler "scaler is built" event (#7820)

New Contributors

@jiyuchen-stripe made their first contribution in #7843

Full Changelog: v2.20.0...v2.20.1

We are happy to release KEDA 2.20.0 🎉

⚠️ Upgrade note: events moved to events.k8s.io (#7781)

With the Kubernetes 0.35 dependency bump, KEDA now records Kubernetes events via the events.k8s.io API group instead of the legacy core events resource. If you deploy KEDA with custom or restricted RBAC, grant the operator create/patch on events.k8s.io/events before upgrading, otherwise event recording will fail. The bundled KEDA manifests and Helm chart already include the updated permissions.

Highlights

Introduce new OpenSearch Scaler

Introduce Elastic Forecast Scaler

Add scalingModifiers fallback behavior

Add support for AWS External ID in TriggerAuthentication podIdentity for all AWS scalers

Add scaler HTTP request metrics for outbound requests made during metric collection

🗓️ The next KEDA release is currently being estimated for 2nd week of September 2026, learn more in our roadmap.

New

• General: Add scalingModifiers fallback behavior (#7366)
• General: Introduce Elastic Forecast Scaler (#7494)
• General: Introduce new OpenSearch Scaler (#7456)

Improvements

• General: Add cooldownPeriod and pollingInterval checks for ScaledObject (#7271)
• General: Add CRD-level validation markers (Minimum, MinLength, MinItems, Enum) for ScaledObject, ScaledJob, ScaleTriggers, and TriggerAuthentication API types (#7533)
• General: Add --leader-election-id flag to allow configuring the leader election Lease name (#7564)
• General: Add scaler HTTP request metrics (keda_scaler_http_requests_total, keda_scaler_http_request_duration_seconds) for outbound HTTP requests made during scaler metric collection (#6600)
• General: Allow more control of TLS versions & ciphers via KEDA_HTTP_TLS_CIPHER_LIST, KEDA_SERVICE_TLS_CIPHER_LIST and KEDA_SERVICE_MIN_TLS_VERSION env vars (#7617)
• General: Cap each scalers-cache reader at a per-reader budget derived from globalHTTPTimeout so ScalersCache.Close cannot block indefinitely (#7574)
• General: Make APIService cert injections optional (#7559)
• General: Remove unconditional json.MarshalIndent calls from admission webhook validation hot paths; replace spec-comparison MarshalIndent-and-string-compare in isRemovingFinalizer variants with reflect.DeepEqual. Prevents webhook OOM under sustained admission load at large scale (observed at ~60k ScaledObjects) (#7670)
• AWS Scalers: Add support for AWS External ID in TriggerAuthentication podIdentity for all AWS scalers (SQS, Kinesis, DynamoDB, CloudWatch, etc.) to enable cross-account access scenarios (#6921)
• Elasticsearch Scaler: Add HTTP status check for Elasticsearch errors (#7480)
• Github Runner Scaler: Handle rate limit errors by respecting X-RateLimit-Reset and Retry-After headers and returning cached queue length (#7683)

Deprecate buildId, selectAllActive, and selectUnversioned because those parameters are used for Rules-Based Worker Versioning, which was a short-lived experimental feature that has been deprecated in the Temporal server since December 2024 and will stop being supported soon. Users of Rules-Based Worker Versioning should use Worker Deployments instead. (#7672)

Fixes

• General: Fix ScaledJob emitting wrong CloudEvent type (ScaledObjectReadyType instead of ScaledJobReadyType) when transitioning to ready state (#7792)
• General: Fix ScaledObject admission webhook to return validation error from verifyReplicaCount, preventing invalid ScaledObjects from being created (#5954)
• General: Fix ScaledObject Ready condition not reflecting HPA status (#7649)

• Azure Pipelines Scaler: Exclude already-assigned jobs from queue length (#7747)
• Cron Scaler: Fix metric name generation so cron expressions with comma-separated values no longer produce invalid metric names (#7448)
• External Scaler: gRPC Pool uses TLS context in the key (#7687)
• Forgejo Scaler: Limit HTTP error response logging (#7469)
• Forgejo Scaler: Return correct activity to enable scale-to-zero (#7527)

• Metrics API Scaler: Fix aggregateFromKubeServiceEndpoints using empty label selector that matched all EndpointSlices in the namespace instead of only the target service's (#7641)
• Metrics API Scaler: Fix division by zero in average aggregation when all kube service endpoints fail (#7742)
• Metrics API Scaler: Prevent response value reflection in scaler errors (#7693)
• NATS JetStream Scaler: Return an error from getMaxMsgLag when the configured consumer is missing instead of falling back to the stream's last sequence, preventing incorrect scale-up to maxReplicaCount (#7657)
• NATS JetStream Scaler: URL-encode user input in monitoring URL construction (#7483)
• PostgreSQL Scaler: Quote whitespace-containing connection parameters in generated connection strings (#7784)
• PredictKube Scaler: Bump dysnix/predictkube-libs to v0.1.0 (drops the predictkube path to the archived/EOL go-grpc-prometheus and to the deprecated golang/protobuf) and use a portable Prometheus-API instant query for the health check so the scaler works against VictoriaMetrics, Thanos and other Prometheus-API-compatible backends (#7745)
• Prometheus Scaler: Handle NaN results in the same manner as Inf (#7475)
• Prometheus Scaler: Limit HTTP error response logging (#7469)
• Pulsar Scaler: Drop bearer/basic auth headers on redirects to a different host or on https->http downgrades to prevent credential leakage (#7686)
