CCIP v1.0.0 has been deprecated on testnet. You must use the new router addresses listed in the CCIP Directory before January 31st, 2024. Please note that there is no change to the router interface. The CCIP v1.0.0 testnet routers will continue to function in parallel until January 31st, 2024, but we highly recommend switching to the v1.2.0 routers as soon as possible. If you currently use CCIP v1.0.0, use the @chainlink/contracts-ccip npm package version 0.7.6. To migrate to v1.2.0, use version 1.2.1 of the npm package or later.

• There is no change to the router interface, but you must use the new router addresses listed in the CCIP Directory.USDC transfers are currently supported on several lanes. See the the CCIP Directory page to get a specific lane's token addresses and rate limits.
• We've simplified the message sequencing process in our CCIP message handling by removing the strict sequencing flag from the extraArgs field in CCIP messages.
• The gas limit and maximum message data length for CCIP messages have been adjusted on testnets. These changes are detailed in the Service Limits documentation.
• To interact with CCIP v1.2.0, use the @chainlink/contract-ccip npm package.
