@ibrahim can you point me where in the docs is this stated? also, is Dgraph using semver? because an incompatible change like this worth a major version change
Also, the error the throw the logs are outdated, as it included a broken link Please see https://github.com/dgraph-io/badger/blob/master/README.md#i-see-manifest-has-unsupported-version-x-we-support-y-error on how to fix this.
