Argo Workflows v3.7.15 - Controller Reliability and Artifact Retries
Argo Workflows v3.7.15 shipped on June 10, 2026 as a stable patch on the 3.7 line. The release tightens semaphore and mutex handling, stops duplicate onExitNode runs, and classifies bare S3 5xx responses as transient so artifact steps retry instead of failing outright.
