 ## Unreleased
 
+### Features
+
+* (evm) [#414](https://github.com/crypto-org-chain/ethermint/pull/414) Integrate go-block-stm for parallel tx execution.
+
+### State Machine Breaking
+
+* (rpc) [#443](https://github.com/crypto-org-chain/ethermint/pull/443) Keep behavior of random opcode as before.
+* (app) [#451](https://github.com/crypto-org-chain/ethermint/pull/451) Disable block gas meter, it's not compatible with parallel tx execution. It's safe to do as long as we checks total gas-wanted against block gas limit in process proposal, which we do in default handler.

 ### Bug Fixes
 
 - (ante) [#422](https://github.com/crypto-org-chain/ethermint/pull/422) vendor `NewDeductFeeDecorator` to re-use the custom `checkTxFeeWithValidatorMinGasPrices` method, so it'll repsect the `DefaultPriorityReduction` config.
