Argo CD v3.3.7 released on 16-04-2026
Argo CD v3.3.7 is out now. Operators and CI/CD teams should check it for a known application controller refresh issue that can prevent apps from syncing or showing resources as out-of-sync.
See the GitHub release notes and the project documentation for installation commands, verification steps for signed artifacts, and ongoing tracking of issue #27344.
What’s in this release
- Known application controller refresh bug: the controller may fail to refresh applications, causing apps not to sync or to not show resources as out-of-sync (see issue #27344).
- Quick start and installation manifests for v3.3.7 with non‑HA and HA commands (apply install.yaml or ha/install.yaml after creating the argocd namespace).
- Signed release artifacts: all container images are signed with cosign and provenance is produced for images and CLI binaries meeting SLSA Level 3; verification documentation is provided.
Upgrade notes
- There is a potential reconciliation bug affecting application refresh. If you rely on automatic refresh/sync behaviour, consider delaying upgrades until the issue is resolved; monitor issue #27344 for progress.
- If upgrading between minor versions, read the official upgrading documentation before you proceed and follow the supplied installation commands for non‑HA and HA deployments.
Share comments on your experience with v3.3.7 and any impact you observe on application refresh or sync behaviour.
