### Added

- Expose error causes as `cause` property ([#140](https://github.com/MetaMask/rpc-errors/pull/140))

## [2.0.0] - 2019-09-26

### Changed

- **Exports**
  - `errors` renamed `ethErrors`

  - `EthJsonRpcError` renamed `EthereumProviderError`
    - It is still a subclass of `EthereumRpcError`
  - **TypeScript**
    - Renamed affected interfaces
- `ethErrors`
  - Added missing
    [EIP-1474 errors](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-1474.md)
    - Added corresponding codes and messages
  - **Namespacing**
    - EIP-1474 (which includes JSON RPC 2.0) errors now namespaced under `ethErrors.rpc`
      - JSON RPC 2.0 errors were formerly under `errors.jsonRpc`
    - EIP-1193 errors now namespaced under `ethErrors.provider`
      - Formerly under `errors.eth`
  - Most error getters now take a single, _optional_ `opts` argument, which
    is either a string or an object
    - If a string, it becomes the error message
    - If an object, it should have the form: `{ message?: string, data?: any }`
    - **Special Cases**
      - `ethErrors.rpc.server` must receive a single object of the form:
        - `{ code: number, message?: string, data?: any }
      - `ethErrors.provider.custom` must receive a single of the form:
        - `{ code: number, message: string, data?: any }
- **TypeScript**
  - Updated affected interfaces

## [1.1.0] - 2019-09-16

### Changed

  - If the object passed to the function has a `.message` property, it will preferred over the `.message` property of the fallback error when creating the returned serialized error object
