Dgraph v2.0.0-rc1 release candidate

Is there any hope for a policy to keep the data format constant within one version number so we can update just the container without the permanent data export-import?

With Dgraph adopting calendar versioning starting in v20.03.0, any patch releases for that release series will not contain any breaking changes.

Has the new GraphQL endpoint actually been tested on an HA cluster?

These should be addressed in the latest v20.03.0 release which was released in March.
