 ## [0.5.0] - 2018-08-27
 - Introduces **support for private chains** by allowing to pass a custom dictionary as the ``chain`` parameter
   in the constructor or the ``setChain()`` method as an alternative to just passing one of the predefined
   ``chain`` ``String`` names (e.g. ``mainnet``, ``ropsten``), PR [#24](https://github.com/ethereumjs/ethereumjs-common/pull/24)
