Added

• Added length and lessthan tasks (pipeline).
• Added gasUnlimited parameter to ethcall task.
• /keys page in Operator UI now exposes several admin commands, namely:
  • "abandon" to abandon all current txes
  • enable/disable a key for a given chain
  • manually set the nonce for a key See this PR for a screenshot example.

Added

• New GAS_ESTIMATOR_MODE for Arbitrum to support Nitro's multi-dimensional gas model, with dynamic gas pricing and limits.
  • NOTE: It is recommended to remove GAS_ESTIMATOR_MODE as an env var if you have it set in order to use the new default.
  • This new, default estimator for Arbitrum networks uses the suggested gas price (up to ETH_MAX_GAS_PRICE_WEI, with 1000 gwei default) as well as an estimated gas limit (up to ETH_GAS_LIMIT_MAX, with 1,000,000,000 default).
• ETH_GAS_LIMIT_MAX to put a maximum on the gas limit returned by the Arbitrum estimator.

Changed

• EIP1559 is now enabled by default on Goerli network

Added

• Added hexencode and base64encode tasks (pipeline).
• forwardingAllowed per job attribute to allow forwarding txs submitted by the job.
• Keypath now supports paths with any depth, instead of limiting it to 2
• Arbitrum chains are no longer restricted to only FixedPrice GAS_ESTIMATOR_MODE
• Updated Arbitrum Rinkeby & Mainnet & Mainnet configurationss for Nitro
• Add Arbitrum Goerli configuration
• It is now possible to use the same key across multiple chains.
• NODE_SELECTION_MODE (EVM.NodePool.SelectionMode) controls node picking strategy. Supported values: HighestHead (default) and RoundRobin:
  • RoundRobin mode simply iterates among available alive nodes. This was the default behavior prior to this release.
  • HighestHead mode picks a node having the highest reported head number among other alive nodes. When several nodes have the same latest head number, the strategy sticks to the last used node. For chains having NODE_NO_NEW_HEADS_THRESHOLD=0 (such as Arbitrum, Optimism), the implementation will fall back to RoundRobin mode.
• New keys eth chain command
  • This can also be accessed at /v2/keys/evm/chain.
  • Usage examples:
    • Manually (re)set a nonce:
      • chainlink keys eth chain --address "0xEXAMPLE" --evmChainID 99 --setNextNonce 42
    • Enable a key for a particular chain:
      • chainlink keys eth chain --address "0xEXAMPLE" --evmChainID 99 --enable
    • Disable a key for a particular chain:
      • chainlink keys eth chain --address "0xEXAMPLE" --evmChainID 99 --disable
    • Abandon all currently pending transactions (use with caution!):
      • chainlink evm keys chain --address "0xEXAMPLE" --evmChainID 99 --abandon
  • Commands can be combined e.g.
    • Reset nonce and abandon all currently pending transaction:
      • chainlink evm keys chain --address "0xEXAMPLE" --evmChainID 99 --setNextNonce 42 --abandon

Changed

• The setnextnonce local client command has been removed, and replaced by a more general key/chain client command.
• chainlink admin users update command is replaced with chainlink admin users chrole (only the role can be changed for a user)

Added

• Arbitrum Nitro client error support

Added

• p2pv2Bootstrappers has been added as a new optional property of OCR1 job specs; default may still be specified with P2PV2_BOOTSTRAPPERS config param
• Added official support for Sepolia chain
• Added hexdecode and base64decode tasks (pipeline).
• Added support for Besu execution client (note that while Chainlink supports Besu, Besu itself has multiple bugs that make it unreliable).
• Added the functionality to allow the root admin CLI user (and any additional admin users created) to create and assign tiers of role based access to new users. These new API users will be able to log in to the Operator UI independently, and can each have specific roles tied to their account. There are four roles: admin, edit, run, and view.
  • User management can be configured through the use of the new admin CLI command chainlink admin users. Be sure to run chainlink adamin login. For example, a readonly user can be created with: chainlink admin users create --email=operator-ui-read-only@test.com --role=view.
  • Updated documentation repo with a break down of actions to required role level
• Added per job spec and per job type gas limit control. The following rule of precedence is applied:

1. task-specific parameter gasLimit overrides anything else when specified (e.g. ethtx task has such a parameter).
2. job-spec attribute gasLimit has the scope of the current job spec only.
3. job-type limits ETH_GAS_LIMIT_*_JOB_TYPE affect any jobs of the corresponding type:

ETH_GAS_LIMIT_OCR_JOB_TYPE    # EVM.GasEstimator.LimitOCRJobType
ETH_GAS_LIMIT_DR_JOB_TYPE     # EVM.GasEstimator.LimitDRJobType
ETH_GAS_LIMIT_VRF_JOB_TYPE    # EVM.GasEstimator.LimitVRFJobType
ETH_GAS_LIMIT_FM_JOB_TYPE     # EVM.GasEstimator.LimitFMJobType
ETH_GAS_LIMIT_KEEPER_JOB_TYPE # EVM.GasEstimator.LimitKeeperJobType

1. global ETH_GAS_LIMIT_DEFAULT (EVM.GasEstimator.LimitDefault) value is the last resort.

Fixed

• Addressed a very rare bug where using multiple nodes with differently configured RPC tx fee caps could cause missed transaction. Reminder to everyone to ensure that your RPC nodes have no caps (for more information see the performance and tuning guide).
• Improved handling of unknown transaction error types, making Chainlink more robust in certain cases on unsupported chains/RPC clients
