v2.9.4

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.
