  ## API-BREAKING

  * [#1146](https://github.com/cosmos/evm/pull/1146) Remove `EndBlocker` based mempool updates, use `PrepareCheckStater` instead.

  ## IMPROVEMENTS

  * [#758](https://github.com/cosmos/evm/pull/758) Cleanup precompiles abi.json.
  * [#810](https://github.com/cosmos/evm/pull/810) Fix integration test suite to resolve lock contention problem from external app injection
  * [#811](https://github.com/cosmos/evm/pull/811) Use sdk's DefaultBondDenom for default evm denom in genesis.
  * [#823](https://github.com/cosmos/evm/pull/823) Remove authz dependency from test suite and EvmApp interface
  * [#829](https://github.com/cosmos/evm/pull/829) Seperate test app interface
  * [#968](https://github.com/cosmos/evm/pull/968) Use normal gas config in ibc transfer to prevent potential DoS attack
  * [#1029](https://github.com/cosmos/evm/pull/1029) Mark EvmCoinInfo.Decimals field as deprecated
  * [#1079](https://github.com/cosmos/evm/pull/1079) Access Control List is now case-insensitive
  * [#1103](https://github.com/cosmos/evm/pull/1103) Align normal gas metering in ibc erc20 callback.
  * [#1108](https://github.com/cosmos/evm/pull/1108) Add json-rpc http server request body limit.
  * [#1118](https://github.com/cosmos/evm/pull/1118) Cache chain denom for evm mempool
  * [#1008](https://github.com/cosmos/evm/pull/1008) Stop enforcing JSON-RPC global filter cap and allow reclaim filters via configurable idle timeout.
  * [#1130](https://github.com/cosmos/evm/pull/1130) Use `sdk.ValidateAuthority` in `x/vm`, `x/erc20`, and `x/feemarket` `MsgServer` handlers so authority can optionally be centralized via the consensus `AuthorityParams` introduced in cosmos-sdk v0.54.
  * [#1164](https://github.com/cosmos/evm/pull/1164) Remove zero gas config from `ics20.transferWithStateDB` so inner KV ops in ICS20 transfer execution are metered, mirroring [#1103](https://github.com/cosmos/evm/pull/1103).

  ## FEATURES

  * New application evm+cosmos mempool ("Krakatoa")
  * [#589](https://github.com/cosmos/evm/pull/589) Remove parallelization blockers via migration from transient to object store, refactoring of gas, indexing, and bloom utilities.
