Release Notes

This page provides detailed release notes for CRE. It includes information on new features, significant changes, and known limitations.

SDK v1.0.2 - January 16, 2026

TypeScript SDK version 1.0.2 introduces several improvements to developer experience:

New features:

  • Optional main() call: You no longer need to call main() at the end of your workflow files. The SDK now automatically executes the main() function during compilation.
  • Automatic error handling: If you don't provide custom error handling, the SDK automatically adds .catch(sendErrorResponse) to your workflow's main() function. This ensures errors are properly reported instead of silently failing.
  • Direct imports: You can now import SDK components directly (e.g., import { HTTPClient } from "@chainlink/cre-sdk") instead of accessing them through the cre namespace (e.g., cre.capabilities.HTTPClient). Both import styles remain supported for backward compatibility.

Migration notes:

  • Custom error handling: If you need custom error handling, you can still add your own .catch() handler: main().catch(myCustomHandler). The SDK will respect your custom handler and not override it.

Release - November 4, 2025

Chainlink Runtime Environment (CRE) is now live. CRE is the all-in-one orchestration layer unlocking institutional-grade smart contracts—data-connected, compliance-ready, privacy-preserving, and interoperable across blockchains and existing systems.

Available now

  • Build and simulate workflows: Create an account at cre.chain.link, install the CRE CLI, and start building workflows using the Go or TypeScript SDKs. Simulate your workflows locally to test and debug before deployment—simulation makes real calls to live APIs and public EVM blockchains.

Early Access

  • Deploy and run workflows: Deploy your workflows to a Chainlink DON with full lifecycle management (deploy, activate, pause, update, delete). Monitor and debug with detailed logs, events, and performance metrics in the CRE UI. To request Early Access, share details about your project.
