Further detailed information can be found on the corresponding [proposal pull request](https://github.com/compound-finance/comet/pull/903).\n\n\n## Proposal Actions\n\nThe proposal contains only 1 action on Mainnet - send message to arbitrum. There are 7 actions on the Arbitrum side: four first ones are update price feeds and three last actions make comet update to new version.';
