+## [6.0.0] - 2018-10-08
+- Support for ``EIP-155`` replay protection by adding an optional ``chainId`` parameter
+  to ``ecsign()``, ``ecrecover()``, ``toRpcSig()`` and ``isValidSignature()``, if present the  
+  new signature format relying on the ``chainId`` is used, see PR [#143](https://github.com/ethereumjs/ethereumjs-util/pull/143)
+- New ``generateAddress2()`` for ``CREATE2`` opcode (``EIP-1014``) address creation
+  (Constantinople HF), see PR [#146](https://github.com/ethereumjs/ethereumjs-util/pull/146)
+- [BREAKING] Fixed signature to comply with Geth and Parity in ``toRpcSig()`` changing 
+  ``v`` from 0/1 to 27/28, this changes the resulting signature buffer, see PR [#139](https://github.com/ethereumjs/ethereumjs-util/pull/139)
+- [BREAKING] Remove deprecated ``sha3``-named constants and methods (see ``v5.2.0`` release),
+  see PR [#154](https://github.com/ethereumjs/ethereumjs-util/pull/154)
