CRE CLI version 1.36.0 is now available. This release adds detailed and classified execution statuses to cre execution status, cre execution list, and cre workflow get, so runs that finish with capability errors are labeled SUCCESS (completed with errors) and platform-caused failures are flagged with a hint. It also fixes telemetry for commands that don't require login, such as cre generate-bindings, cre workflow build, and cre workflow hash.

Update your CLI by running cre update when prompted, or follow the CLI Installation guide for fresh installations.

Ethereum is upgrading to Glamsterdam during Q4 2026, which changes the gas model of the chain. No action is required unless your workflow sets a gas limit.

Timelines:

• Ethereum Sepolia — 6 October 2026 at 13:53:36 UTC
• Ethereum Hoodi — Q4 2026 (to be confirmed)
• Ethereum Mainnet — Q4 2026 (to be confirmed)

Onchain writes to each network may fail for roughly 30 minutes before and after its upgrade. If your workflow sets a gas limit, start testing against Ethereum Sepolia from 6 October 2026 (add gas headroom or unset the gas limit), then update your workflows for Ethereum Mainnet once it is upgraded.

See Network Upgrades for details.

Scheduled (cron-based) updates for the Data Feeds listed below are being sunset. These updates were deprecated in August 2025 and will be fully shut down on or shortly after September 30, 2026.

These feeds are not being deprecated. Only the scheduled updates that request a new round at a fixed time are being removed. Each feed continues to update normally based on its heartbeat and deviation thresholds.

Affected feeds:

Ethereum

• ETH / USD
• BTC / USD
• LINK / USD
• UNI / USD
• SUSHI / USD
• AAVE / USD

Avalanche

• AVAX / USD
• BTC / USD
• ETH / USD
• MIM / USD
• LINK / USD
• USDC / USD

Polygon

• Calculated MaticX / USD

Arbitrum

• BTC / USD
• ETH / USD
• ARB / USD
• SOL / USD
• TIA / USD
• DOGE / USD
• PEPE / USD

No action is required if your integration relies on heartbeat and deviation-threshold updates. If your integration depends on updates at a specific time, review your implementation before September 30, 2026.

Chainlink Data Feeds are now available on Stellar. Data Feeds on Stellar use a single proxy contract that serves every feed, and consumers select a feed by its 32-byte data_id rather than a per-feed contract address.

See Using Data Feeds on Stellar to get started, and Price Feed contract addresses for Stellar for feed IDs and onchain parameters.

Chainlink Node v2.66.0 is now available. See the Release Notes for details.

CCIP 2.0 introduces new opt-in features:

• Additive security: Add issuer, third-party, or institution-operated Cross-Chain Verifiers (CCVs) for additional verification and control. The default remains the secure, battle-tested CCIP DON.
• Faster-than-finality (FTF) transfers: Control confirmation parameters for standard or faster-than-finality cross-chain execution, tailored to your needs and risk threshold. The default remains waiting for full finality.
• Modular fee components: Customize fees for your token or your verifier.
• Built-in compliance functions: Native integration with the Chainlink Automated Compliance Engine (ACE) enables policy checks without breaking composability.
• Permissionless execution / No Exec: Customize execution by opting into No Exec (more controlled execution), using a custom executor, or executing permissionlessly. The default remains the Chainlink executor service.

The CCIP Architecture Overview explains the new modular architecture of CCIP 2.0. The Router contract, CCIP's single point of interface, remains unchanged on all networks.

This release ships with a full suite of developer tooling, including the CCIP API, SDK, CLI, and CCV Starter Kit.

CCIP is no longer supported on Superseed Sepolia.

Chainlink Node v2.65.0 is now available. See the Release Notes for details.

CRE CLI version 1.35.0 is now available. This release adds support for Ethereum Hoodi Testnet for local simulation via cre workflow simulate and for production onchain writes. The Go SDK (v1.21.0) and TypeScript SDK (v1.22.0) add the corresponding EthereumHoodiTestnet chain constant.

Update your CLI by running cre update when prompted, or follow the CLI Installation guide for fresh installations.
