v2.9.6

Compare Source

Highlights

Flux v2.9.6 is a patch release that stops helm-controller from reapplying chart CRDs on every upgrade when server-side apply is enabled, and recovers HelmReleases left with a drifted Ready=Unknown condition after a failed status patch. source-controller normalizes Azure Blob listing ETags so unchanged containers are no longer re-downloaded on every reconcile, and evicts stale Helm repository index entries from the cache so repositories with frequently changing indexes no longer fail with "Cache is full". kustomize-controller extends SOPS decryption error redaction to spec.postBuild.substituteFrom values, so substituted secrets echoed back in API validation errors are masked out of status conditions and events, and adds the opt-in DisableCommitStatusEvent feature gate. Users are encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Stop reapplying chart CRDs on upgrades when using server-side apply with the default Create policy (helm-controller)
• Recover HelmReleases stranded with a drifted Ready=Unknown condition after a failed status patch (helm-controller)
• Ignore NotFound when deleting the HelmChart (helm-controller)
• Normalize Azure Blob listing ETags so unchanged containers are not re-downloaded on every reconcile (source-controller)
• Evict stale Helm repository index entries from the cache to avoid "Cache is full" errors (source-controller)
• Extend SOPS decryption error redaction to spec.postBuild.substituteFrom values (kustomize-controller)

Improvements:

• Add the opt-in DisableCommitStatusEvent feature gate (kustomize-controller)

v2.9.5

Compare Source

Highlights

Flux v2.9.5 is a patch release that moves helm-controller and source-controller back to upstream Helm, now at v4.2.4, dropping the temporary Flux fork. It hardens the handling of kubeconfig Secrets in helm-controller and kustomize-controller, which now reject kubeconfigs referencing files on the local filesystem and require credentials and certificates to be embedded inline. It also stops kustomize-controller from leaving behind the temporary directories of a previous process that exited without running its cleanup, and fixes a crash in post-build substitution where a substring expression with a negative length, e.g. ${VAR:2:-1}, panicked instead of counting back from the end of the string like Bash does. Across all controllers and the CLI, the fluxcd/pkg dependencies have been updated, bringing Kubernetes to 1.36.4. Users are encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Validate kubeconfigs from .spec.kubeConfig Secrets, rejecting local file references in certificate-authority, tokenFile, client-certificate and client-key; credentials and certificates must be embedded inline (helm-controller, kustomize-controller)
• Purge temporary directories at startup (kustomize-controller)
• Fix panic on negative-length substring expressions in post-build substitution (kustomize-controller, flux CLI)

Improvements:

• Move back to upstream Helm v4.2.4, dropping the Flux fork (helm-controller, source-controller)
• Update fluxcd/pkg dependencies, which bring Kubernetes to 1.36.4 (all controllers, flux CLI)

v2.9.4

Compare Source

Highlights

Flux v2.9.4 is a patch release that ships various fixes to the Flux controllers, covering source-watcher tarball extraction and glob expansion limits, the refspecs accepted by ImageUpdateAutomation, the HTTP request limits of the notification-controller servers, and Helm repository index loading, OCI chart digest pinning, Bucket error handling and GCS static authentication in source-controller. On the CLI side, flux migrate -f now supports migrating repositories to Flux 2.9. Users are encouraged to upgrade for the best experience.

Note that this release contains CRD schema changes for ArtifactGenerator and ImageUpdateAutomation; both CRDs must be updated along with the controllers.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Confine tarball extraction and bound glob expansion (source-watcher)
• Disallow force-update and deletion via refspecs (image-automation-controller)
• Unify HTTP server request limits (notification-controller)
• Align Helm repository index loading with upstream Helm v4 (source-controller)
• Improve error handling in Bucket reconciliation (source-controller)
• Pin OCI chart verification by digest (source-controller)
• Limit GCS static authentication to service account keys (source-controller)
• Restrict the allow-webhooks network policy to the receiver port (flux CLI)

Improvements:

• Add support for migrating repositories to 2.9 in flux migrate -f (flux CLI)
• Update fluxcd/pkg dependencies, which align the ECR host detection with upstream (source-controller, image-reflector-controller, flux CLI)
• Update Bitbucket Cloud receiver guidance (notification-controller)

v2.9.3

Compare Source

Highlights

Flux v2.9.3 is a patch release. It fixes empty lines vanishing from rendered Helm chart manifests, HelmReleases being marked as tested when their Helm test hooks never ran, and spec.images entries that set only some image fields discarding the remaining fields already declared for the same image in the kustomization.yaml. The latter affects both kustomize-controller and the flux build|diff kustomization commands. Users are encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Fix empty lines vanishing from rendered chart manifests (helm-controller)
• Fix HasBeenTested for all corner cases, where a release could be marked as tested although its Helm test hooks never ran (helm-controller)
• Fix a spec.images entry setting only some of the image fields discarding the remaining fields already declared for the same image in the kustomization.yaml at spec.path, e.g. overriding only newName produced an untagged image reference (kustomize-controller, flux CLI)

Improvements:

• Update fluxcd/pkg dependencies
• Include source-watcher in the OCI flux-manifests artifact

v2.9.2

Compare Source

Highlights

Flux v2.9.2 is a patch release. The main fix addresses a regression introduced in
v2.9.1 where a Kustomization with openapi.path pointing to a URL failed to
reconcile with failed to read OpenAPI schema. This release also corrects several
CRD field descriptions that contained inaccurate or leaked content. Users are
encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Fix a regression where a Kustomization with openapi.path pointing to a URL failed to reconcile with failed to read OpenAPI schema (kustomize-controller)
• Fix the HelmChart CRD description for .status.url, which pointed users at BucketStatus.Artifact instead of HelmChartStatus.Artifact (source-controller)
• Fix the ImageRepository CRD description for .status.observedExclusionList, which referred to spec.lastScanResult instead of status.lastScanResult (image-reflector-controller)
• Fix the ImageUpdateAutomation CRD description for .status.observedSourceRevision, which had a stray Go struct declaration leaking into it (image-automation-controller)

v2.9.1

Compare Source

Highlights

Flux v2.9.1 is a patch release. The main fix, applied across all controllers, disables Flux variable substitution on the Flux CRDs by annotating them with kustomize.toolkit.fluxcd.io/substitute: disabled, so that Kustomizations with post-build substitution enabled no longer corrupt the CRD schemas when they contain ${...} sequences. Users are encouraged to upgrade for the best experience.

ℹ️ Please follow the Upgrade Procedure for Flux v2.7+ for a smooth upgrade from Flux v2.6 to the latest version.

Fixes:

• Disable Flux variable substitution on all Flux CRDs, preventing post-build substitution from corrupting CRD schemas that contain ${...} sequences (all controllers)
