Argo CD v3.3.3 released on 09-03-2026
Argo CD v3.3.3 is out now. It delivers straightforward non‑HA and HA install flows and a set of stability fixes and signed release artefacts that make secure cluster onboarding and verification easier for operators.
See the GitHub release for the install manifests and commands, the operator documentation for signature and provenance verification, the full changelog comparing v3.3.2…v3.3.3, and the release blog post for a deeper breakdown.
What’s in this release
- Quick start install: non‑HA and HA flows using kubectl apply against the published manifests (manifests/install.yaml and ha/install.yaml) on the v3.3.3 release path for fast cluster onboarding.
- Signed release assets and provenance: all container images are signed with cosign and provenance metadata is produced for container images and CLI binaries meeting SLSA Level 3; operator docs explain how to verify signatures and provenance.
- Notable bug fixes and cherry‑picks: fixes include correct CNPG suspend/resume annotation handling, comma‑separated hook annotations for PreDelete/PostDelete hooks, health reporting using note.drySha when present, standard resource icon fixes in the UI, improved kubeversion consistency with Helm 3, and multi‑level cross‑namespace hierarchy traversal corrections.
