Argo
v3.3.5CI/CD & App DeliveryArgo CD v3.3.5 is a patch release fixing a stack overflow bug, hook ordering issues, and UI improvements — low risk, high value to upgrade.
breakingCircular ownerRef crash is now fixed — upgrade if you hit mysterious crashes
If your cluster has resources with circular ownership references (common in some operators or misconfigured CRDs), Argo CD could stack overflow and crash during graph processing. This is now fixed. If you've seen unexplained application-controller crashes, this is almost certainly the cause. Patch immediately.
breakingPostSync hooks silently skipped when PreDelete/PostDelete hooks coexist — fixed
Workflows relying on PostSync hooks for notifications, cleanup, or validation were silently broken if the same app also defined PreDelete or PostDelete hooks. Verify your hook-based pipelines after upgrading to confirm they now execute correctly.
enhancementgrpc dependency bumped to 1.79.3
The grpc library was bumped from 1.77.0 to 1.79.3. This picks up several upstream fixes. No action required beyond upgrading, but if you run Argo CD in a security-sensitive environment, review the grpc changelog for any CVEs addressed in that range.
