-    "description": "Chainlink CCIP 1.5 is now available on testnet, introducing several new features and enhancements.\n\n**Risk Management Network Coverage:**\nCertain CCIP integrations may not initially include the Risk Management Network (RMN). Blockchains can be integrated with CCIP in a phased approach, starting with the deployment of the Committing and Executing Decentralized Oracle Networks (DONs), followed by the addition of the Risk Management Network in a subsequent update. During a phased deployment, the relevant Commit Stores are configured in the Risk Management contract to always be considered blessed until the Risk Management Network has been deployed for that blockchain. Please refer to the [Supported Networks](https://docs.chain.link/ccip/supported-networks) documentation to identify which integrations utilize a phased approach, and review the [CCIP Service Responsibility](https://docs.chain.link/ccip/service-responsibility) for more information.\n\n**New Version of `EVMExtraArgs`:**\nChainlink CCIP 1.5 introduces a new version of `EVMExtraArgs`, allowing users to set the `allowOutOfOrderExecution` parameter. This feature enables developers to control the execution order of their messages on the destination blockchain. The `allowOutOfOrderExecution` parameter is part of [`EVMExtraArgsV2`](https://docs.chain.link/ccip/api-reference/client#evmextraargsv2) and is available only on lanes where the **Out of Order Execution** property is set to **Optional** or **Required**. Please consult the [Supported Networks page](https://docs.chain.link/ccip/supported-networks) to determine if your target lane supports this feature.",
