Argo CD v3.3.6 released on 27-03-2026
Argo CD v3.3.6 is out now. Operators and deployers get explicit quick-start commands for both non‑HA and HA installs, signed container images with provenance that meet SLSA Level 3 for images and binaries, and a small set of bug fixes addressing diff detection and a cached installation ID.
Visit the v3.3.6 tag on GitHub for the raw manifests, the documentation for signature and provenance verification, and the full changelog for complete details.
What’s in this release
- Quick Start: exact kubectl commands for non‑HA and HA installs using server-side apply with –force-conflicts and the v3.3.6 manifests (non‑HA: manifests/install.yaml; HA: manifests/ha/install.yaml).
