Argo CD v3.4.3 released on 28-05-2026
Argo CD v3.4.3 is out now. Operators get signed container images and provenance (SLSA Level 3), straightforward quick‑start manifests for single‑instance and HA installs, and a set of targeted bug and dependency fixes for CLI, controller and UI behaviour.
See the GitHub release and the operator documentation for the install manifests, signature‑verification guidance and the full changelog.
What’s in this release
- Quick‑start installs for Non‑HA and HA: create the argocd namespace and apply manifests/install.yaml (Non‑HA) or manifests/ha/install.yaml (HA) using server‑side apply with –force‑conflicts.
- Signed releases and provenance: all Argo CD container images signed with cosign and provenance metadata produced for images and CLI binaries meeting SLSA Level 3; verification guidance is available in the operator docs.
- Bug fixes and improvements: CLI ‘app wait’ now returns immediately if the app is already in the desired state; UI fixes to avoid prefetch errors and return full source for non‑hydrator apps; controller fixes for repo depth handling, startup race prevention, truncated labels on deletion hooks and nil checks to prevent panics; gitops‑engine nil‑pointer fix.
