+### Latest js-ipfs
+This release also brings compatibility with the latest version of js-ipfs (v0.66.0).
+
+### Level v8.0.0
+In addition, we've updated the underlying data storage, [Level](https://github.com/Level), to its latest version v8.0.0. We've dropped the automatic migration from Level < v5.0.0 stores, so if you have databases that use and old version of Level, please see the [Upgrading Guide](https://github.com/Level/level/blob/master/UPGRADING.md) for Level on how to migrate manually.
+
+### Misc
+We've also fixed various bugs across the code base, updated all dependencies to their latest versions and removed the ES5 distribution builds.
+
+Note that there are no API changes to OrbitDB in this release.
