+## [7.0.1] - 2020-05-15
+
+This patch release downgrades the re-exported `BN.js` version from `v5` to
+`v4` (so a continuation of what has being used within the `v6.x` versions).
+This is due to some unexpected interoperability problems in libraries using
+the older `v4` `BN.js` branch in their some of their respective dependencies.
+
+An upgrade is highly recommended, the `v7.0.0` release will be marked as
+deprecated along this release.
