According to the company’s changelog, that match-any behavior applies to filters for logs, the dead-letter queue and cancellations.\n\nAt the API level, the label option on client.trigger and context.invoke accepts either a string or an array of strings. Reading labels changes too: workflow run logs expose a labels: string[] field, and context.labels: string[] replaces the now-deprecated context.label. The June entry does not identify a package version or an exact release day.\n\nA separate entry, dated March 2026, addresses notifications that arrive before a workflow is ready to wait for them. Upstash says an optional workflowRunId parameter on notify enables “lookback”: notifications are stored and delivered even if sent before the workflow reaches waitForEvent. The company describes this as preventing race conditions. It is an earlier change, not part of the June labeling update.","content_kind":"author_paraphrase","explanation":{"feature":"The TypeScript SDK accepts multiple labels per run, while context.labels replaces the deprecated singular field.","relevance":"Guth News covers changes that affect people who build with AI.
