v2.4.0Compare Source
Highlights
Flux v2.4.0 is a feature release. Users are encouraged to upgrade for the best experience.
For a comprehensive overview of new features and API changes included in this release, please refer to the Announcing Flux 2.4 GA blog post.
This release marks the General Availability (GA) of Flux Bucket API. The
Bucketv1 API comes with new features including: proxy support, mTLS and custom STS configuration for AWS S3 and MinIO LDAP authentication.The
GitRepositoryv1 API gains support for OIDC authentication. Starting with this version, you can authenticate against Azure DevOps repositories using AKS Workload Identity.The
OCIRepositoryv1beta2 API gains support for proxy configuration thus allowing dedicated HTTP/S Proxy authentication on multi-tenant Kubernetes clusters.The
HelmReleasev2 API gains support for disabling JSON schema validation of the Helm release values during installation and upgrade. And allows adopting existing Kubernetes resources during Helm release installation.The Flux controllers are now built with Go 1.23 and their dependencies have been updated to Kubernetes 1.31, Helm 3.16, SOPS 3.9 Cosign 2.4 and Notation 1.2.
❤️ Big thanks to all the Flux contributors that helped us with this release!

Upgrade Flux from
v2.3.0tov2.4.0either by rerunning bootstrap or by using the Flux GitHub Action.To upgrade the APIs, make sure the new CRDs and controllers are deployed, and then change the manifests in Git:
apiVersion: source.toolkit.fluxcd.io/v1in the YAML files that containBucketdefinitions.Bumping the APIs version in manifests can be done gradually.
It is advised to not delay this procedure as the deprecated versions will be removed after 6 months.

v2.2.0Compare Source
Highlights
Flux v2.2.0 is a feature release. Users are encouraged to upgrade for the best experience.
The Flux CLI and controllers have been updated to Kustomize v5.3.0 and Kubernetes v1.28.4.
Flux helm-controller's reconciliation model underwent a significant overhaul, addressing persistent issues such as the automatic recovery of releases stuck in a pending state. In addition, it improves the observability of the release status, and it introduces the ability to enable drift detection on a per-object basis. For more details on the helm-controller improvements, please see the Announcing Flux 2.2 GA blog post.
The Flux CLI can now be used to force or reset the reconciliation state of a
HelmReleasev2beta2 object usingflux reconcile hr --forceandflux reconcile hr --reset.Flux CLI comes with support for bootstrapping Gitea repositories and adds guardrails to
flux installandflux bootstrapto protect users from destructive operations. Theflux versionandflux checkcommands now print the Flux distribution version deployed on the cluster.The Flux alerting capabilities have been extended with NATS and Bitbucket Server & Data Center support.
Starting with this release, Flux minor versions are benchmark to measure the Mean Time To Production (MTTP). The results for this version can be found at
github.com/fluxcd/flux-benchmark.
❤️ Big thanks to all the Flux contributors that helped us with this release!
Kubernetes compatibility
This release is compatible with the following Kubernetes versions:
v1.26>= 1.26.0v1.27>= 1.27.1v1.28>= 1.28.0Note that Flux may work on older versions of Kubernetes e.g. 1.25, but we don't recommend running end-of-life versions in production nor do we offer support for these versions.
API changes
HelmRelease v2beta2
The HelmRelease kind was promoted from v2beta1 to v2beta2.
The v2beta2 API is backwards compatible with v2beta1, the v2beta1 API is deprecated and will be removed in a future release.
Deprecated fields:
.patchesStrategicMergeand.patchesJson6902Kustomize post-rendering fields have been deprecated in favor of.patches..status.lastAppliedRevisionand.status.lastReleaseRevisionfields have been deprecated in favor of.status.history..status.lastAttemptedValuesChecksumhas been deprecated in favor of.status.lastAttemptedConfigDigest.New fields:
.spec.driftDetection.modefield..spec.driftDetection.ignore.spec.test.filtersfield..status.historyfield. This includes any Helm test results when enabled..status.lastHandledForceAtand.status.lastHandledResetAtfields have been introduced to track the last time a force upgrade or reset was handled.Alert and Provider v1beta3
The Alert and Provider kinds were promoted from v1beta2 to v1beta3.
The v1beta3 API is backwards compatible with v1beta2, the
.statusfield was removed making the resources static objects. Any errors encountered while sending notifications are now recorded as Kubernetes Events associated with the Alert objects.Bucket v1beta2
A new field,
.spec.prefix, has been added to the Bucket API, which enables server-side filtering of files if the object's.spec.provideris set togeneric,awsorgcp.OCIRepository and HelmChart v1beta2
Two new fields,
.spec.verify.matchOIDCIdentity.issuerand.spec.verify.matchOIDCIdentity.subjecthave been added to the HelmChart and OCIRepository APIs. If the image has been keylessly signed via Cosign, these fields can be used to verify the OIDC issuer of the Fulcio certificate and theOIDC identity's subject respectively.
HelmRepository and ImageRepository v1beta2
A new boolean field,
.spec.insecure, has been introduced to theHelmRepository and ImageRepository APIs, which allows connecting to a non-TLS HTTP container registry. For HelmRepositories it is only considered if the object's
.spec.typeis set tooci.From this release onwards, HelmRepository objects of type OCI are treated as static objects, i.e. they have an empty status.
Upgrade procedure
Upgrade Flux from
v2.xtov2.2.0either by rerunning bootstrap or by using the Flux GitHub Action.To upgrade the APIs, make sure the new CRDs and controllers are deployed, and then change the manifests in Git:

Flux v2.1.0 is a feature release. Users are encouraged to upgrade for the best experience.
The Flux APIs were extended with new opt-in features in a backwards-compatible manner.
The Flux Git capabilities have been improved with support for Git push options, Git refspec, Gerrit, HTTP/S and SOCKS5 proxies.
The Flux alerting capabilities have been extended with Datadog support.
The Flux controllers come with performance improvements when reconciling Helm repositories with large indexes (80% memory reduction), and when reconciling Flux Kustomizations with thousands of resources (x4 faster server-side apply). The load distribution has been improved when reconciling Flux objects in parallel to reduce CPU and memory spikes.
