+## [4.0.3] - 2019-12-19
+
+Supports `MuirGlacier` by updating `ethereumjs-block` to
+[v2.2.2](https://github.com/ethereumjs/ethereumjs-block/releases/tag/v2.2.2)
+and `ethereumjs-common` to
+[v1.5.0](https://github.com/ethereumjs/ethereumjs-common/releases/tag/v1.5.0).

+This release comes also with a completely refactored test suite, see
+PR [#134](https://github.com/ethereumjs/ethereumjs-blockchain/pull/134).
+Tests are now less coupled and it gets easier to modify tests or extend
