## Unreleased
### Bug Fixes
* (evm) [\#621](https://github.com/cosmos/ethermint/issues/621) EVM `GenesisAccount` fields now share the same format as the auth module `Account`.
* (app) [\#617](https://github.com/cosmos/ethermint/issues/617) Fix genesis export functionality.
## [v0.3.1] - 2020-11-24
### Improvements
* (deps) [\#615](https://github.com/cosmos/ethermint/pull/615) Bump Cosmos SDK version to [v0.39.2](https://github.com/cosmos/cosmos-sdk/tag/v0.39.2)
