### Bug Fixes
* (evm) [\#661](https://github.com/cosmos/ethermint/pull/661) Set nonce to the EVM account on genesis initialization.
* (rpc) [\#648](https://github.com/cosmos/ethermint/issues/648) Fix block cumulative gas used value.
* (evm) [\#621](https://github.com/cosmos/ethermint/issues/621) EVM `GenesisAccount` fields now share the same format as the auth module `Account`.
* (evm) [\#618](https://github.com/cosmos/ethermint/issues/618) Add missing EVM `Context` `GetHash` field that retrieves a the header hash from a given block height.
* (app) [\#617](https://github.com/cosmos/ethermint/issues/617) Fix genesis export functionality.
