Argo
v3.3.8CI/CD & App DeliveryArgo CD v3.3.8 is a patch release with six bug fixes targeting core mode syncs, AppSet resource limits, CLI diff accuracy, and informer cache staleness.
breakingRefresh behavior changed again — validate your autosync pipelines
The revert of the informer resync fix means refresh behavior is back to pre-3.3.7 state. If you tuned anything around reduced refresh frequency after upgrading to 3.3.7, re-examine those assumptions. Check autosync event logs to confirm expected behavior before promoting to production.
enhancementCore mode users: upgrade immediately to unblock syncs
The missing server.secretkey bug caused silent sync failures in core mode deployments — a serious operational gap that's easy to miss in monitoring. If you run Argo CD in core mode, this patch is not optional. Upgrade, then verify sync status across all applications post-upgrade.
enhancementLarge ApplicationSets now default to 5,000 resource status entries
If you manage ApplicationSets with hundreds of apps, you may have hit the old resource status count ceiling without realizing it. After upgrading, review any ApplicationSets that showed truncated or missing resource statuses and confirm they now report correctly.
