CLI v1.2.0 - February 26, 2026

CRE CLI version 1.2.0 is now available.

  • Dynamic template fetching: Templates are now fetched at runtime from GitHub, so cre init always offers the latest available templates without requiring a CLI update. Two new cre templates commands let you manage template sources — run cre templates list to browse available templates, or cre templates add to include custom or third-party repositories. See Template Sources for details.
  • Deploy access management: New cre account access command lets you check your organization's deployment access status and submit an Early Access request directly from the CLI. See Requesting Deploy Access for details.
  • Unit tests for TypeScript templates: TypeScript workflow templates now include a unit test setup out of the box
  • Bug Fix: Fixed an issue where secrets were not correctly injected during workflow simulation in certain configurations.

How to update:

  • Automatic update: When you run any CRE command, the CLI will automatically detect if a newer version is available and prompt you to update. Simply run cre update to install the latest version.
  • Fresh installation: If you're installing the CLI for the first time, follow the CLI Installation guide.

Confidential HTTP Capability - February 25, 2026

CRE now supports the Confidential HTTP capability for production workflows, allowing you to make privacy-preserving API calls with enclave execution. See the Making Confidential Requests guide to learn more.

CLI v1.1.0 - February 18, 2026

CRE CLI version 1.1.0 is now available.

  • Custom WASM builds: New cre workflow custom-build command converts a workflow to use a custom Makefile-based build process. Use this when you need custom compiler flags, build tags, CI/CD artifact promotion, or non-standard toolchains. See the Custom WASM Builds guide for details.
  • Improved CLI interface: The CLI has a refreshed visual output across all commands — styled errors, progress indicators, and spinners during long-running operations make it easier to follow what's happening.

How to update:

  • Automatic update: When you run any CRE command, the CLI will automatically detect if a newer version is available and prompt you to update. Simply run cre update to install the latest version.
  • Fresh installation: If you're installing the CLI for the first time, follow the CLI Installation guide.

TS SDK v1.1.0 - February 18, 2026

TypeScript SDK version 1.1.0 includes improvements to error handling, Confidential HTTP behavior, and developer experience:

  • Improved error messages: Error messages across the runtime, codegen, and utilities are now more descriptive and actionable
  • Confidential HTTP runs in DON mode: The Confidential HTTP capability now executes in DON mode (instead of node mode), aligning with how other DON-level capabilities work
  • Clearer setup errors: The SDK now provides a descriptive error when cre-setup has not been run before attempting to compile a workflow

Go SDK v1.3.0 - February 12, 2026

Go SDK version 1.3.0 updates the Confidential HTTP capability types.

  • Confidential HTTP: The encrypt_output field has moved from ConfidentialHTTPRequest to HTTPRequest. Update any workflows using ConfidentialHTTPRequest.encrypt_output to set this field on the inner HTTPRequest instead.

TS SDK v1.0.3 - January 19, 2026

  • Bug Fixes: Fixed issue where workflows could execute twice during simulation

  • Examples Updated: All workflow examples in the SDK repository now use direct imports (e.g., import { HTTPClient } from "@chainlink/cre-sdk") instead of the namespace pattern (e.g., cre.capabilities.HTTPClient). Both patterns remain fully supported—choose whichever fits your coding style. See Import styles for details.

TS 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. See main() reference for details.
  • 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. See Import styles for details and guidance on when to use each pattern.

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. See main() reference for examples.

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.
