 ### State Machine Breaking
 
 - [#1232](https://github.com/crypto-org-chain/cronos/pull/1232) Adjust require gas in relayer precompile to be closed with actual consumed.
+- [#1209](https://github.com/crypto-org-chain/cronos/pull/1209) Support accurate estimate gas in evm tx from relayer.
 
 ### Improvements
 
 - [#1239](https://github.com/crypto-org-chain/cronos/pull/1239) Refactor websocket/subscription system to improve performance and stability.
 - [#1241](https://github.com/crypto-org-chain/cronos/pull/1241) Improve parallelization of memiavl restoration.
