TypeScript SDK (workflow-js):
Introduced third-party integrations, starting with Anthropic, Resend, and OpenAI. These integrations are automatically offloaded to workflows, ensuring long-running calls do not consume user environment time. See the related documentation here. Added a timeout parameter to context.call. Learn more in the documentation. Improved support for workflows in Express and SvelteKit by adding the useJSONContent option. Resolved loop detection issues on Cloudflare and Render. Full changelog, including all fixes, is available here.
Workflow Server:
Added the WorkflowCreatedAt filter for Dead Letter Queue (DLQ) and Events. Prepared the local development server for public release (coming soon). Enhanced context.SleepUntil to support float values. Increased the event retention period from 10,000 events to up to 14 days. Learn more on the Pricing page.
