v3.2.8CI/CD & App Delivery

Mar 26, 2026Copy link

A targeted patch release fixing a gRPC CVE, a false-diff bug in app normalization, and a UI glitch in RollingSync — upgrade promptly for the security fix alone.

• securityPatch CVE-2026-33186 by upgrading to v3.2.8 now

  The grpc-go CVE-2026-33186 fix is the primary reason to move quickly on this release. If you're running any 3.2.x version, upgrade to 3.2.8. Verify your container images using cosign against the published provenance — the Argo CD docs cover the exact verification steps. Don't wait on this one.

• breakingCheck for spurious sync operations before and after upgrade

  The normalization diff bug could have been silently triggering syncs on apps that were actually in-sync. After upgrading, review your sync history for apps that synced frequently without visible config changes — those were likely false positives. The fix should stop them, but any automation or alerts built around sync frequency may need recalibration.

• enhancementRollingSync UI fix improves progressive delivery visibility

  If you use ApplicationSets with RollingSync and have ever wondered why a step appeared blank or unclear in the UI, this fix addresses that. No action needed beyond upgrading, but it's worth re-examining your RollingSync step configurations in the UI post-upgrade to confirm everything displays as expected.
