+- Removed `stateRoot` check for `Account.isEmpty()` to make emptiness check `EIP-161` compliant, PR [#279](https://github.com/ethereumjs/ethereumjs-util/pull/279)
+- Added type `AddressLike` and helper `bnToHex()`, PR [#279](https://github.com/ethereumjs/ethereumjs-util/pull/279)
+- Added `account.raw()` which returns a Buffer Array of the raw Buffers for the account in order, PR [#279](https://github.com/ethereumjs/ethereumjs-util/pull/279)
